Hardware Products

The TempScan/1100 and MultiScan/1200 are high-speed, compact, rack-mountable instruments that
measure up to 992 or 744 channels of temperature or voltage, respectively. Because of their unique
architecture, both instruments offer unrivaled low cost per channel. They connect to a computer via
IEEE 488 or RS-232/RS-422 interfaces, or via Hayes-compatible modem, and can be disconnected
from the computer for stand-alone operation.

TempScan/1100

The TempScan/1100 is well-suited for temperature and lower-voltage measurement because its solid­state scanning provides temperature readings at speeds up to 960 channels per second, an important
feature in applications that require monitoring of tens or hundreds of channels.

MultiScan/1200

The MultiScan/1200 is ideal for temperature and voltage measurements that require channel-to-channel
isolation. The unit provides 500 V of channel-to-channel isolation for voltage, and 200 V of channel­to-channel isolation for thermocouples. The MultiScan/1200 uses relays to provide isolation and to
scan thermocouples and volts at up to 147 channels per second. The unit can also digitize waveforms
on a single channel at up to 20 kHz.

TempScan / MultiScan User's Manual Chapter 1: System Overview 1

Exp/10A Expansion Unit

The TempScan/1100 and MultiScan/1200 master units can each control up to fifteen Exp/10A two-slot
expansion units, for a maximum of 30 additional scanning cards. The Exp/10A form factor is identical
to that of either master unit. When attached to the TempScan/1100, the Exp/10A is configurable for 32
or 64 input channels, providing a total expansion capacity of up to 992 channels. When attached to the
MultiScan/1200, the Exp/10A is configurable for 24 or 48 input channels, providing a total expansion
capacity of up to 744 channels.

Exp/11A Expansion Unit

Alternatively, the TempScan/1100 and MultiScan/1200 master units can each control up to three
Exp/11A ten-slot expansion units, for a maximum of 30 additional scanning cards. Like the Exp/10A,
the Exp/11A form factor is identical to that of either master unit. When attached to the
TempScan/1100, the Exp/11A provides up to 320 input channels in a compact enclosure, providing a
total expansion capacity of up to 992 channels. When attached to the MultiScan/1200, the Exp/11A
provides up to 240 input channels, providing a total expansion capacity of up to 744 channels.

For TempScan/1100 systems consisting of more than 96 channels, or for MultiScan/1200 systems
consisting of more than 72 channels, the Exp/11A ten-slot expansion unit provides an economical and
convenient solution.

TempScan/1100 Scanning Cards

The TempScan/1100 master unit and any Exp/10A and Exp/11A expansion units connected to this
master unit, can each accept the following three kinds of optional solid-state scanning cards:

• TempTC/32B thermocouple scanning card

•

TempV/32B voltage scanning card

•

TempRTD/16B RTD scanning card

Each scanning card contains screw-terminal blocks for quick and easy input connections. A padded
hold-down for restraining wires and several tie-down holes for strapping down the wires, are provided
to keep wires from all the channels organized and manageable. To keep noise outside and to maintain
a constant internal temperature, each scanning card fits into a shielded metal enclosure inside the
master or expansion unit.

MultiScan/1200 Scanning Cards

The MultiScan/1200 master unit and any Exp/10A and Exp/11A expansion units connected to this
master unit, can each accept the following two kinds of optional scanning cards:

• MTC/24 thermocouple/volt scanning card

•

MHV/24 high-voltage scanning card

Like the TempScan/1100 scanning cards, each of these scanning card contains screw-terminal blocks
for quick and easy input connections. A padded hold-down for restraining wires and several tie-down
holes for strapping down the wires, are provided to keep wires from all the channels organized and
manageable. To keep noise outside and to maintain a constant internal temperature, each scanning card
fits into a shielded metal enclosure inside the master or expansion unit.

Hardware Configuration

The TempScan/1100 or MultiScan/1200 unit is equipped with a high-speed IEEE 488 interface and an
RS-232/RS-422 interface. Its IEEE 488 interface is useful in laboratory applications and enables real­time transfers of acquired data to the host computer’s hard drive for inexpensive mass storage. Its RS­232/RS-422 interface is ideal in applications that require the placement of instrumentation at remote
distances from the controlling computer, such as process and environmental control.

This unit can be set up with an IEEE 488 or a RS-232/RS-422 interface configuration, as determined
by the DIP switch accessible from the rear panel. This DIP switch via its nine microswitches select
which command set is to be used – IEEE 488 or RS-232/RS-422 – and the operating parameters for
each. The table shows the options for its nine microswitches. Additional DIP switch settings are
shown in the following sections.

The rear panel DIP switch is read only during power-on or reset and should be set before applying
power. To modify any of these defaults, change the microswitch settings using a small screwdriver.
The enclosure does not need to be opened to change these settings.

IEEE 488 Configuration

One way in which the TempScan/1100 or MultiScan/1200 unit can be controlled, is through its
IEEE 488 port connector. Consequently, when configured as an IEEE 488 bus device, the unit must
have an IEEE 488 bus address.

DIP Switch

For IEEE 488 operation, the single microswitch labeled COMM SELECT should be down (0) on the
rear panel DIP switch . This down (0) position is the factory default. The up (1) position is reserved
for RS-232/RS-422 serial communication. When IEEE 488 operation is enabled, the five
microswitches labeled IEEE ADDRESS are used to configure the required IEEE 488 bus address.

The bus address can be set from 0 through 30 and is read only at power-on or reset. The address is
selected by simple binary weighting. The switch labeled 1 is the least significant bit (LSB); 16 is the
most significant bit (MSB). The factory default is bus address 7. Note that if address 31 is selected, it
defaults to address 30 because the IEEE 488 standard has reserved address 31.

The rear panel DIP switch is read only during power-on or reset and should be set before applying
power. To modify any of these defaults, change the microswitch settings using a small screwdriver.
The enclosure does not need to be opened to change these settings.

RS-232/RS-422 Serial Configuration

Alternatively, the TempScan/1100 or MultiScan/1200 unit can be controlled through its serial port
connector. Complete serial port configuration is accomplished by using both internal jumpers and DIP
switch settings. The internal jumpers, located on the main board behind each serial connector, are used
to configure the port with either RS-232 or RS-422 electrical characteristics. The DIP switch, located
on the rear panel, is used to determine handshaking, parity, and baud rate. Furthermore, the selection
of an RS-232 or RS-422 electrical configuration determines the serial port pattern of pin connector
signals, as discussed later.

Internal Jumpers

The jumpers within the unit configure the serial port electrically as either RS-232 or RS-422. To
change the serial port configuration, it is necessary to perform the following steps:

of hardware jumpers located on the main board behind the serial connector. A 12-position jumper
plug must be inserted in one of the two available positions for proper operation (across JP11 and
JP12 for RS-232, across JP12 and JP13 for RS-422). These jumpers are factory set for RS-232 as
shown in the figure. To reconfigure the serial port for RS-422 operation, remove the jumper plug
and reinsert it into the lower 2 rows of jumpers.

TempScan / MultiScan User's Manual Chapter 2: TempScan/1100 & MultiScan/1200 19

4. If configured for RS-422, the port’s Receive Data (RxD+) and Clear to Send (CTS+) input lines

may optionally be terminated with a 100-Ohm resistor. Termination resistors are selected by
positioning the two flea clips (labelled JP14 and JP15). These jumpers are factory set to the
unterminated position, as indicated in the previous figures. Note that when using RS-422 in a
single-ended configuration, ports must be unterminated. Termination jumpers have no effect when
the port is configured for RS-232 operation.

5. Once the jumper(s) have been repositioned for your application, make note of the new jumper

settings for later reference.

6. Carefully reassemble the unit.

Note:

For re-assembly, first reconnect the AC power line (with the power OFF), next reconnect the
scanning cards, and then any other cables, prior to reapplying power to the entire system.

DIP Switch

To configure the TempScan/1100 or MultiScan/1200 for RS-232/RS-422 serial operation, the single
microswitch labeled COMM SELECT must be up (1) on the rear panel DIP switch . The down (0)
position is reserved for IEEE 488 communication. When serial operation is enabled, additional DIP
microswitches configure the following required parameters: Handshaking, parity, and baud rate.

Handshaking. When the RS-232 port is used, the type of handshaking must be selected by the two
microswitches labeled H/S. The options available are: No handshaking, XON/XOFF, RTS/CTS or
both XON/XOFF and RTS/CTS handshaking. Note that XON/XOFF handshaking is valid for ASCII
transmissions only, and for RS-422 operation with a Macintosh, RTS/CTS handshaking is not
recommended.

Parity. The parity must be selected using the two microswitches labeled PARITY. The options
provided are: No parity, odd parity or even parity.

Baud rate. The baud rate is selected using the three microswitches labeled SERIAL BAUD RATE. The
available baud rates are 300, 600, 1200, 2400, 4800, and 9600.

Note:

(1) XON/XOFF handshaking is valid for ASCII transmissions only. (2) At 9600 baud,
hardware (RTS/CTS) handshaking and possibly software (XON/XOFF) handshaking may be
required to maintain serial performance. However, for RS-422 operation with a Macintosh,
RTS/CTS handshaking is not recommended.

The rear panel DIP switch is read only during power-on or reset and should be set before applying
power. To modify any of these defaults, change the microswitch settings using a small screwdriver.
The enclosure does not need to be opened to change these settings.

The following text describes the various pin connector signals:

• Transmit Data Negative (TxD-): This output pin transmits serial data to an RS-232 or RS-422

device. The serial data received is sent with the word length, baud rate, stop bits, and parity
configured for the particular port. This signal is low true.

• Transmit Data Positive (TxD+): This output pin transmits serial data to an RS-422 device only.

The pin functions identically to TxD- except that its polarity is inverted. This signal is high true.

• Receive Data Negative (RxD-): This input pin accepts serial data sent by an RS-232 or RS-422

device. The serial data received is expected to match the word length, baud rate, stop bits, and
parity configuration of the particular port. This signal is low true.

• Receive Data Positive (RxD+): This input pin accepts serial data sent by an RS-422 device only.

It functions identically to RxD- except that its polarity is inverted. This signal is high true.

• Request To Send Positive (RTS+): This output pin is used as a hardware handshake line to prevent

an RS-232 or RS-422 device from transmitting serial data to the TempScan/1100 or
MultiScan/1200 unit when it is not able to accept it. When automatic RTS/CTS handshaking is
selected, the unit will assert (high) the RTS+ signal when greater than 4096 memory locations are
available in its internal buffers. If available memory drops below 4096 bytes, the unit unasserts
(low) the RTS+ signal.

• Request To Send Negative (RTS-): This output pin is used as a hardware handshake line with an

RS-422 device only. The pin functions identically to RTS+ except that its polarity is inverted.
This signal is low true.

• Clear To Send Positive (CTS+): This input pin is used as a hardware handshake line to prevent the

TempScan/1100 or MultiScan/1200 unit from transmitting serial data to an RS-232 or RS-422
device when it is not able to accept it. When RTS/CTS handshaking is selected, the unit will not
Transmit Data (TxD+) out while the CTS+ signal is un-asserted (low). When XON/XOFF or no
handshaking is selected, the CTS+ line is ignored.

• Clear To Send Negative (CTS-): This input pin is used as a hardware handshake line with an RS-

422 device only. It functions identically to CTS+ except that its polarity is inverted. This signal is
low true.

• Ground (GND): This signal sets the ground reference point for the other RS-232/RS-422 input

and output signals.

Calibration Protection Configuration

The chassis calibration constants and the calibration password are stored by the TempScan/1100 or
MultiScan/1200 in Non-Volatile RAM (NV-RAM). The password is a safety feature used to prevent
unauthorized personnel from entering calibration mode and altering the calibration constants.

As a safeguard, the calibration password and chassis calibration constants are hardware protected. This
protection is enabled by setting the microswitch 9 to the down (0) position on the rear panel DIP
switch. This is the default factory setting and should remain in this position unless purposely
attempting to change the password or chassis constants.

If it is necessary to change the calibration password (via the
this hardware write protection can be disabled by setting microswitch 9 to the up (1) position. For
details on calibration, see chapter System Calibration.

Do not forget to set back the DIP microswitch 9 to the down (0) position when

calibration is complete. Otherwise, the calibration password and calibration
constants may be corrupted and normal operation may be disrupted.

Digital I/O Configuration

Located on the TempScan/1100 or MultiScan/1200 rear panel, the DB50 digital I/O connector provides
eight (8) digital input lines and thirty-two (32) digital output lines. The figure and table locate and
describe the input, output, and ground lines of this connector.

CAUTIONCAUTION

Do not exceed the levels described. Otherwise, the TempScan/1100 or

MultiScan/1200 unit may be damaged in a way that is not covered by the
warranty.

TTL Output & Trigger Input Configuration

The rear panel of the TempScan/1100 or MultiScan/1200 unit also provides two external BNC
connectors: The TTL output and the trigger input. The BNC TTL scan output is used for
synchronizing equipment with TempScan/1100 or MultiScan/1200 acquisition, while the BNC trigger
input is used for starting and/or stopping acquisition of the TTL output. This trigger input can be
programmed to activate on a rising (positive-going) or falling (negative-going) TTL level edge. Any
TTL level signal (> 2.2V = Hi, < 0.8V = Lo) may be used as a trigger pulse. A trigger pulse may also
be used to generate a Service Request. Note that the TTL Out is a LS-TTL compatible output, 0.4 mA
sourcing, 8 mA sinking. When a scan is logged into the acquisition buffer(after the actual scan), the
TTL output signal is pulsed for 100 ms. Refer to the timing diagram.

Expanded Memory Configuration

Either the TempScan/1100 or MultiScan/1200 can accommodate up to 8 MBytes of memory, which is
ideal for both high-speed and long-term data logging. Measurements can be stored in memory and read
out by a controlling computer as time permits. Readings may be transferred at up to 300 KBytes per
second over the IEEE 488 bus, or up to 9600 baud using the unit’s standard RS-232/RS-422 port.

Three memory options are provided for expanding the standard 256 KB memory: 1 MB (TempMEM1
or MultiMEM1), 4 MB (TempMEM4 or MultiMEM4), or 8 MB (TempMEM8 or MultiMEM8). To
install a memory option into the unit, it is necessary to perform the following steps:

Never disassemble the case while it is connected to the AC power line! Internal

voltage potentials exist which could cause bodily injury or death!

Never disconnect the AC power line from the TempScan/1100 or MultiScan/1200

Scanning Card & Channel Expansion

Scanning Card Expansion

Each TempScan/1100 or MultiScan/1200 unit can accept one scanning card to provide signal
conditioning. However, if your application demands more channels then you can expand the master
unit’s capabilities with either or both types of expansion units: Exp/10A and/or Exp/11A. Each
Exp/10A expansion unit allows for the addition of two scanning cards, while each Exp/11A expansion
unit allows for the addition of ten scanning cards. Up to fifteen Exp/10A units can be attached to the
master unit, giving a maximum of 30 additional scanning-card slots. Similarly, up to three Exp/11A
units can be linked to the master unit, also giving a maximum of 30 additional scanning-card slots, as
shown in the following table.

Expansion Capabilities Exp/10A Exp/11A

Number of expansion scanning-card slots per expansion unit 2 10
Number of identical expansion units that can be linked to the master unit 15 3
Maximum number of expansion scanning-card slots 30 30

Note:

If a combination of Exp/10A and Exp/11A expansion units are linked together, then the
maximum number of expansion scanning-card slots is still 30.

Channel Expansion

The TempScan/1100 system can be expanded up to 992 channels, while the MultiScan/1200 system
can be expanded up to 744 channels. This is easily accomplished via a master/slave architecture
wherein a main or master unit can be connected to as many expansion slave units as allowable within
the maximum of 30 scanning cards.

Each Exp/10A or Exp/11A expansion unit has a form factor identical to that of either the
TempScan/1100 or MultiScan/1200 master unit, allowing the expansion unit to accept the same
scanning cards as its master unit. When connected to the TempScan/1100, the Exp/10A or Exp/11A is
configurable for 32 or 64 input channels, providing a total expansion capacity of up to 992 channels.
When connected to the MultiScan/1200, the Exp/10A or Exp/11A is configurable for 24 or 48 input
channels, providing a total expansion capacity of up to 744 channels.

An expansion unit can only be controlled by the TempScan/1100 or MultiScan/1200 master unit, and
no digital I/O or alarms are included. However, expansion channels can be programmed to stimulate
the alarms located on the master unit. From the programmer’s perspective, channels are accessed in the
same way as channels in the master unit. When the master unit detects the presence of expansion units
during its power-on sequence, it makes the additional channels available to the programmer. The
command is available to query the master unit for the total number of channels in the system.

A general description of both types of expansion units, their connections and their configurations, is
discussed in the following chapters.

6. Turn power on to the master unit.

7. Turn power on to the remaining system devices.

30 Chapter 3: Exp/10A Expansion Unit TempScan / MultiScan User's Manual

Slave Configuration

For the master/slave configuration to operate correctly, the master unit must either be a
TempScan/1100 or MultiScan/1200; it cannot be an Exp/10A or Exp/11A expansion unit.

Furthermore, each Exp/10A unit must be assigned a unique slave address. Following simple binary
weighting, this slave address is set by using microswitches 5 through 8 of the rear panel DIP switch. In
the following figure, DIP microswitch 8 is in the up position, indicating the default slave address 1.

With all four microswitches 5, 6, 7 and 8 in the up position, this setting indicates a slave address of 15
(8 + 4 + 2 + 1). A maximum of 15 Exp/10A slave addresses can be set, while the address of 0 is not
allowed. The Exp/10A factory default is address 1.

CAUTION

CAUTION

CAUTIONCAUTION

Avoid linking two or more expansion chassis with the same slave address.

Otherwise, the unspecified addresses may result in operating errors.

Note:

The address of 0 is not allowed because this is reserved for the master unit address.

Channel Assignment

Channels 1 through 32 are always in the TempScan/1100, and channels 1 through 24 are always in the
MultiScan/1200, while the channels in the Exp/10A expansion unit are treated as extended channels.
With the first Exp/10A slave unit, the first channel in the first scanning card is channel 33 in the
TempScan/1100 system, and channel 25 in the MultiScan/1200 system. With the same slave unit, the
first channel in the second scanning card is channel 65 in the TempScan/1100 system, and channel 49
in the MultiScan/1200 system. The order of multiple Exp/10A expansion units are set up using the rear
panel DIP switches, as described earlier.

Even if a scanning card slot is left empty in the master unit and/or slave unit(s), the channel
assignments remain the same, as shown in the table. For a 16-channel TempScan/1100 scanning card,
the system still assigns 32 channels to the card slot with the second 16 channels ignored. Likewise, for
a 12-channel MultiScan/1200 scanning card, the system still assigns 24 channels to the card slot with
the second 12 channels ignored. For example, if a 16-channel TempRTD/16B scanning module is
installed in the first slot of Logical Unit 2 (the first Exp/10A), then channels 33 through 48 will be
assigned and channels 49 through 64 will be ignored.

Hardware Configuration

Master/Slave Connection

Up to three Exp/11A expansion units can be connected to the TempScan/1100 or MultiScan/1200
master unit, giving options of up to 30 expansion scanning cards. Connect the expansion unit as
described in the following steps:

Before connecting an Exp/11A expansion unit to its master unit, or to another
expansion unit, power down all devices that are connected or to be connected.
Failure to do so could damage the equipment.

To Connect the Exp/11A Expansion Unit

1. Turn power off and unplug the master unit and all devices connected to the system.

2. If not already done so, turn power off and unplug the Exp/11A unit(s) which are to be connected.

3. Connect the master/slave cable(s) (CA-35-1) as depicted in the following illustration.

CAUTION

CAUTION

CAUTIONCAUTION

4. Plug in all system devices.

5. Set the slave address on the rear panel DIP switch. See next section Slave Configuration.

6. Turn power on to the master unit.

7. Turn power on to the remaining system devices.

36 Chapter 4: Exp/11A Expansion Unit TempScan / MultiScan User's Manual

Slave Configuration

For the master/slave configuration to operate correctly, the master unit must either be a
TempScan/1100 or MultiScan/1200; it cannot be an Exp/10A or Exp/11A expansion unit.

Furthermore, each Exp/11A unit must be assigned a unique slave address. Following simple binary
weighting, this slave address is set by using microswitches 1 and 2 of the rear panel DIP switch. In the
previous figure, DIP microswitch 1 is in the LOW position while DIP microswitch 2 is in the HI
position, indicating the slave address 1. A maximum of 3 Exp/11A slave addresses can be set – 0, 1,
and 2 – while the address of 3 is not allowed. The Exp/11A factory default is address 0.

CAUTION

CAUTION

CAUTIONCAUTION

Avoid linking two or more expansion chassis with the same slave address.

Otherwise, the unspecified addresses may result in operating errors.

Note:

The address of 3 is invalid. If this address is set, the LED indicator ERROR will light up.

Channel Assignment

Channels 1 through 32 are always in the TempScan/1100, and channels 1 through 24 are always in the
MultiScan/1200, while the channels in the Exp/11A expansion unit are treated as extended channels.
With the first Exp/11A slave unit, the first channel in the first scanning card is channel 33 in the
TempScan/1100 system, and channel 25 in the MultiScan/1200 system. With the same slave unit, the
first channel in the second scanning card is channel 65 in the TempScan/1100 system, and channel 49
in the MultiScan/1200 system. The order of multiple Exp/10A expansion units are set up using the rear
panel DIP switches, as described earlier.

Even if a scanning card slot is left empty in the master unit and/or slave unit(s), the channel
assignments remain the same, as shown in the table. For a 16-channel TempScan/1100 scanning card,
the system still assigns 32 channels to the card slot with the second 16 channels ignored. Likewise, for
a 12-channel MultiScan/1200 scanning card, the system still assigns 24 channels to the card slot with
the second 12 channels ignored. For example, if a 16-channel TempRTD/16B scanning module is
installed in the first slot of Logical Unit 2 (the first Exp/10A), then channels 33 through 48 will be
assigned and channels 49 through 64 will be ignored.

Introduction

The TempScan/1100 master unit and any Exp/10A and Exp/11A expansion units connected to this
master unit, can each accept the following three kinds of optional solid-state scanning cards:

•

TempTC/32B Thermocouple Scanning Card which measures thermocouples

• TempV/32B Voltage Scanning Card which measures voltages

• TempRTD/16B RTD Scanning Card which measures RTDs (resistance temperature devices)

Note:

Each scanning card contains screw-terminal blocks for quick and easy input connections. Connections
are made by inserting the wire into a screw-terminal socket.

Several tie-down holes are provided for tie-wrap strain reliefs to keep wires from all the channels
organized and manageable before they exit the rear panel of the master or expansion unit.

To keep noise outside and to maintain a constant internal temperature, each scanning card fits into a
shielded metal enclosure inside the master or expansion unit. The foam padding on the scanning card
provides an air dam to minimize gradients.

Do not mix TempScan/1100 and MultiScan/1200 scanning cards within the same system.
TempScan/1100 scanning cards are designed for and supported only by the TempScan/1100
master unit. Likewise, MultiScan/1200 scanning cards are designed for and supported only by
the MultiScan/1200 master unit. Otherwise, operating errors or equipment damage may
occur.

TempTC/32B Description

The TempTC/32B thermocouple scanning card contains 32 differential input channels, each of which
may be configured as any thermocouple type or as a millivolt input. Temperature values may be
returned in units of °C, °F, °K, °R, or mV.

There is a 4700-picofarad polypropylene capacitor connected across the input terminals of each
channel. This capacitor acts to filter some of the input noise when measuring thermocouples. When
the circuit card is set to the ±100 millivolt range, this capacitor will react with the user source
impedance to form a low-pass filter. The filter pole frequency will be 1/(2*pi*(RSHI + RSLO)*4700 *

When making differential voltage measurements with the TempTC/32B card, you should insure that
one of the common terminal blocks is connected to the common of the unit being measured.

TempV/32B Description

The TempV/32B voltage scanning module contains 32 differential input channels and is capable of
measuring analog input signals on any of four programmable ranges: ±100 millivolt, ±1 volt, ±5 volt
and ±10 volt.

For differential input configuration, each input must have biasing currents. A certain amount of current
must be flowing into the differential inputs or else capacitance-induced noise will make the inputs
appear as noise.

The low side of each differential input channel is provided with a switchable 10-kΩ resistor to analog
common. This allows a current path when no current is flowing due to no common ground connections
or a high-impedance input source. With no common ground connection, closing the switch connects a
10-kΩ resistor between the (L) input and ground and provides a common mode impedance.

The relationships between the DIP microswitches and specific channels are described in the table.

To change the operating voltage of the TempScan/1100, MultiScan/1200, Exp/10A, and/or Exp/11A
unit, it is necessary to open the enclosure. However, before modifying the voltage, disconnect any
input or output connections from the rear panel of the affected unit and then disconnect the power cord
from the power line terminal.

Line voltage must be set for 105-125 or 210-250 VAC to match the power being supplied to the
TempScan/1100, MultiScan/1200, Exp/10A, and/or Exp/11A unit. If the line voltage is changed, the
fuse must also be changed. Refer to the following text for the line voltage switch and fuse locations.

TempScan / MultiScan User's Manual Chapter 7: Power & Assembly 49

Line Voltage Selection

As already mentioned, the TempScan/1100, MultiScan/1200, Exp/10A and Exp/11A unit can each
operate with 105-125 or 210-250 VAC, 50-60 Hz power, as set by its internal line-voltage switch
(labelled S2 or SW2). Each unit is shipped from the factory with this operating voltage setting marked
on its rear panel. If this is not the appropriate power setting to be supplied to the unit, then the line
voltage and power fuse must be changed to avoid damage to the unit. The locations of switch S2 or
SW2 and the fuse are shown in the figures. The line-voltage selection procedure is outlined in the

Power-Up Activation

At initial power-up or on the Reset Power-On (*R) command, the TempScan/1100 or MultiScan/1200
performs automatic self-tests to ensure that it is fully functional. The front panel LED indicators show
any errors if they occur. Possible error conditions and their corresponding LED indicator patterns are
shown in the following table. Any LED pattern not shown is an internal error that is not field­serviceable; in this case, contact the factory. If ERROR is on by itself, there is a configuration error
due to setup information in NV-RAM. Check the error using the Query Error Status (

E?) command.

LED Indicators

If no problems are found, the POWER LED indicator will remain on while the rest of the indicators will
go out, and the TempScan/1100 or MultiScan/1200 will begin its power-up initialization. This self test
is performed each time the unit is powered up regardless of whether power-on was caused by the power
switch or the Reset Power-On (

*R) command. During initialization, the self test performs the following

steps:

1. Checks for errors at power-up.

2. Checks the flag in the NV-RAM to determine if it should power-up with factory default settings or

a user-defined configuration.

3. Loads appropriate registers with corresponding values in NV-RAM.

4. Checks a flag to see if alarms should be enabled at power-up, and if so, enables them.

5. Loads channel configuration registers.

6. Loads program sequencer with appropriate channel configurations.

7. Resets computations processor to begin acquiring scans.

The self test takes approximately five seconds to complete, after which the TempScan/1100 or
MultiScan/1200 unit is ready for normal operation.

Introduction

ChartView is a graphic Microsoft Windows-based program which can be used for various data
acquisition applications. The program was designed for ease-of-use with no need for programming or
expertise in configuration. ChartView Plus provides enhanced features – including overlapping
channels (up to four overlapping channels per chart), alarm logging, multiple groups, and Auto Re-arm
– which can be activated by the use of a registration ID number. Please consult your service
representative for more detailed information.

ChartView and ChartView Plus provide you with the capability to connect to and control any member
of the TempScan/1100 or MultiScan/1200 family of data acquisition instruments, as well as perform
the following tasks:

• Create and edit chart display setups.

• Set up analog input parameters (selecting Channels, Channel Types, Units) to acquire data.

• Configure alarms (and log alarms with ChartView Plus).

•

• View real-time display of channel data via the Main Window and Meters indicators.

• Save data to disk.

• Transmit data to Microsoft Excel via DDE (Dynamic Data Exchange).

• Start PostView, an independent application that allows you to graphically view post-acquisition

Configure and arm an acquisition.

channel data from a file.

•

Use remote RS-232 communications by attaching the acquisition device to a modem configured
for Auto Answer.

An understanding of the following basic concepts will help you master ChartView more quickly, and
should be understood before starting the program.

TempScan / MultiScan User's Manual Chapter 8: ChartView & ChartView Plus 55

Groups, Charts & Channels

When starting the program with no configuration file present (see
Chapter 1 if necessary), a feature called Chart Setup Wizard is
automatically activated to assist you with your display setup. To make
the best use of Chart Setup Wizard you need to understand the
relationship of Groups, Charts, and Channels.

Group. “Group” refers to a group of charts. Note that ChartView
program makes use of one chart group. ChartView Plus allows up to 64
groups, depending on the capabilities of your PC, but can only display
one group at a time.

Chart. “Chart” refers to display area which reflects real-time channel
data values for a selected channel and can be scrolled at various rates.
You can assign up to 16 charts per group. ChartView Plus enables each
chart to display up to four overlapping channels.

Channel. “Channel” refers to a signal channel. Channels will be
displayed in units of °C, °F, °K, °R, mV, V, or in user-defined units,
depending on the configuration and type of signal conditioning card
used. With ChartView Plus you can have up to 4 overlapping channels
assigned to one chart.

Using ChartView

Charting vs. Acquisition To-Disk. ChartView has two distinct operations; displaying real-time data
and saving collected data to disk. These two operations are completely independent of one another. As
such, ChartView can display data in its real-time indicator without arming a "to-disk" acquisition, or it
can arm a "to-disk" acquisition without displaying the data in its real-time indicators.

Regardless of the state of the to-disk acquisition, when enabled, the real-time indicators, including the
charts, always display the current channel values. Regardless of whether the to-disk acquisition is
disarmed, waiting for trigger, or in the post-trigger state, the channel values viewed in the real-time
indicators always reflect the current values of the channels.

Hardware/Software Interaction & Stand-Alone Operation. The intelligent acquisition hardware
handles all aspects of the acquisition, including triggering, scan timing, and data buffering. ChartView
simply provides a method for the user to configure the data collection parameters and download them
to the hardware. Once the hardware is configured, it has the capacity to perform the acquisition
without computer intervention. As the instrument collects the data, it stores it in its internal buffer in
preparation for uploading it to the computer.

56 Chapter 8: ChartView & ChartView Plus TempScan / MultiScan User's Manual

As a default, when a to-disk acquisition is armed, ChartView constantly polls the instrument, uploading
available scans and storing them to disk. This polling operation, however, can be disabled so that the
instrument will operate in a totally stand-alone mode, buffering scans in its internal buffer indefinitely.
As its internal buffer becomes full, it posts a buffer overrun error and continues to store scans,
overwriting the oldest data in the buffer.

If ChartView's polling feature has been turned off, ChartView can be directed at any time to upload the
instrument's current buffer contents and save it to the disk file. If you turn on the polling feature,
ChartView will upload the instrument's current buffer contents, then continue to poll the instrument,
uploading the instrument's newly buffered data periodically.

Some of the data acquisition scenarios that pertain to ChartView are as follows:

Channel Information Region

Channels can return values in units of °C, °F, °K, °R, mV, V,
or user defined units (if the mX + b option is used). With
exception of mX + b user defined units, units depend on the
configuration and type of signal conditioning card used.
Signal conditioning cards are detailed in the user’s manual for
you data acquisition device. The Channel Information Region
is located on the right-hand side of ChartView’s main
window. The values displayed in this region are the real-time
values of the selected channel.

By clicking on the up or down arrows (

σ

, or τ) by the channel
selection box (item 14), you can select one of a maximum of 4
channels that were assigned to that chart. You could then
observe the chart-related information for that specific channel.
You can also select a new channel for the information region
by placing the cursor in (or tabbing over to) the “Center” or
“Units/Div” fields and then pressing PageUp or PageDown. This is particularly useful when your
main window has been re-sized such that the channel selection boxes are not visible.

The following list identifies the various areas of the region.

13 Chart Max. Scale Value

(Grid Limit Line)

14 Channel Selection

(Of chart’s available channels)
15 Multiply (x2) 19 Chart Min. Scale Value (Grid Limit Line)
16 Present Value 20 Divide (÷2)

17 Center

(Value at chart mid-line)

18 Units/Division

(Provides the vertical increment of one grid box.)

Note: The basic ChartView program does not permit overlapping channels or having more than

1 chart group. Multiple group applications (ChartView Plus) can be activated by use of a
special code, allowing up to 4 overlapping channels per chart. Regardless of whether you are
using the basic ChartView program, or ChartView Plus, there is a maximum limit of 16 charts
per group.

Multiply and Divide Buttons -

In addition to reading channel values, you can increase or decrease the
size of the selected channel’s chart. This is accomplished with the Multiply (15) and Divide (20)
push-buttons. The Multiply push-button effectively increases the size of the selected channel’s chart by
a factor of 2, while automatically adjusting the chart’s high and low values (items 13 and 19). Aside
from “clicking” on the Multiply/Divide controls, you can use your keyboard spacebar to control this
feature once the button (15 or 20) is selected. Selection may be with mouse, or by tabbing over to the
control.

Making changes to a channel’s chart parameters does not affect the parameters of the other channels,
with the following exception: Holding the keyboard’s control key down while adjusting either spinner
(

σ/τ

) for center (item 17), or spinner for units/div (item 18) causes the parameter change to apply to all
channels displayed for the chart, not just the currently selected channel display. This feature applies to
the spinners and keyboard up and down arrow keys, but not to the text input.

Center Control - The Center

control (item 17) changes the value of the selected channel’s chart

centerline. Changing the value of center results in an automatic change of the chart’s high and low end
values (items 13 and 19), and possibly an automatic change of the units/div (item 18). Aside from
using the center spinner controls to change center, you can change the center value by placing the
mouse cursor in (or tabbing over to) the field and then either typing in the desired value, or using the
PC keyboard up and down arrow control keys.

Units/div - The units in units/div

(18) can be °C, °F, °K, °R, mV, or V. The division referenced is one
vertical grid. In the example above for Channel 1, each vertical grid increment represents 10.58°C per
division. Changing the units/division spinner controls (

σ/τ

) will result in an automatic adjustment of the
max scale and min scale values (items 13 and 19). Aside from using the units/div triangular controls to
change the value, you can change units/div by placing the mouse cursor in (or tabbing over to) the field
and then either typing in the desired value, or using the PC keyboard arrow control keys.

Group Select

This feature indicates the chart group which is being charted. Clicking on the down arrow (τ) reveals
other chart groups configured by the user. The standard ChartView program allows the use of only one
chart group, while ChartView Plus can be configured to display up to 64 groups (one group at a time).
To select a different chart group, simply pull down the group list and select the desired group. The
group list can be obtained by any of the control options provided in the Main Window table. These are:
a) clicking the down arrow (
arrow key, d) using the page up or page down key. If using a control option other than “a,” you may
need to select the group select box by repeatable pressing the keyboard’s Tab key until the group select
box is selected. When this happens the name of the currently selected group appears in white on a dark
background.

Start, Pause & Stop Charts

As their names imply, these three buttons are used to start, pause, or stop the charts. Pressing “pause”
suspends chart scrolling, but does not stop the “charting” process. While “pause” is pressed, the
channel region of the main window will continue to display real time values. Pressing “pause” a
second time restarts the scrolling action. Pressing “stop” causes the charting process to stop and
instantly freezes the channel region at its present values. This does not affect the acquisition.

Scroll Faster & Scroll Slower

These buttons provide a means of speeding up and slowing down the chart’s scrolling rate, also
referred to as chart speed. These two buttons do not affect the scan rates of the acquisition device. The
chart speed (item 23) is indicated in the lower right-hand corner of the main window as time/div. There
are 14 possible chart speeds, as follows:

0.1 sec/div 1 sec/div 10 sec/div 2 min/div 30 min/div

0.2 sec/div 2 sec/div 30 sec/div 5 min/div 1 hr/div

0.5 sec/div 5 sec/div 1 min/div 10 min/div

Display Configuration Setup

The Display Configuration button accesses a Display Configuration Setup dialog box. This box will
also be displayed if: a) Create Charts Manually is selected during use of the Wizard Chart Setup
program, b) you select Setup from the Chart pull-down menu, c) you right-click on the chart region in
ChartView’s Main Window.

Note: If multiple chart groups are present in the display configuration, the current group will be

selected in the display configuration tree.

When you first click on the Display Configuration button, a Display Configuration Setup box appears.
A display region shows the configured structure of the groups, charts, and channels. From this box you
can select the number of charts to be assigned to a specific group. With the use of the mouse cursor
you can also select a chart or channel for additional editing.

In addition to the text presented in the following sub-sections: Normal Edit and Manually Creating a
Display, you can refer to the following for related information: Chart Setup Wizard on page 93
provides information on the use of Chart Setup Wizard for the set up of groups, charts, and channels.

The method you use to access the Display Configuration Setup window makes a difference. When you
use the toolbar button or the pull-down menu’s Setup selection, the Display Configuration Setup
window appears with the current chart display configuration intact. With this type of access you
would simply edit your existing chart display. Channel and alarm configurations do not change, with
exception that newly displayed channels will be enabled.

When you access the Display Configuration Setup from the Chart Setup Wizard, the Display
Configuration Setup window appears with no existing display. This allows for a “clean slate” approach
to creating a chart display, as opposed to an “editing” approach. Channel and alarm configurations do
not change, with exception that newly displayed channels will be enabled.

TempScan / MultiScan User's Manual Chapter 8: ChartView & ChartView Plus 63

Normal Edit

Display Configuration Setup Dialog Box with an Existing Configuration

To explain editing a configuration, we make use of an example in which assumes you want to edit
Chart 1. In the following figure, Chart 1 was highlighted by clicking on it with the mouse cursor. The
Display Configuration Setup box then changed, allowing you to see specific channel types (such as
volts only) or to “Show all Types,” as in the example. From this setup box you can add or delete charts
and channels. You can:

• hold down the Shift key and use the cursor to select several consecutive channels for addition or deletion

• hold down the Ctrl key and use the cursor to select several non-consecutive channels for addition or deletion

• double-click on an available channel to add it to the selected channels

• double-click on a selected channel to remove it from the selected channels list

Note: When a chart contains overlapping channels and the channels share values such that their

traces reside on top of each other, then the channels that are listed lower in the display list (the
most recently added channels) will obscure the channels higher in the list (those which were
added first).

Adding Channel 2 to Chart 1

64 Chapter 8: ChartView & ChartView Plus TempScan / MultiScan User's Manual

Another variation of the Display Configuration Setup box appears when you highlight a channel. In the
following figure, Channel 1 (of Chart 1, Group 1) was selected, resulting in a new screen image. From
this screen you can edit the channel setup.

Adjusting Channel Setup for Channel 1

ChartView and ChartView Plus data channels can operate in one of two modes: Units Full Scale or,

Units/Div. The mode is selected by radio button.

Units Full Scale. When Units Full Scale is selected, as depicted in the above figure, you can alter
Y Max and Y Min. These are the upper and lower limits of the Channel as they will appear on the
chart when the channel is selected. When you change either parameter, Y Center and Units/Division
are automatically adjusted. You can not directly adjust Y Center or Units/Division while “Units Full
Scale” is selected. You can change Y Max and Y Min by using the up and down arrows, or by
highlighting the existing value, typing in the new value, the pressing “Enter” on your PC keyboard.

Note: If the window size is changed, a chart operating in the Units Full Scale mode will maintain its

full scale setting across the chart.

Units/Div. When Units/Div. is selected you can alter Y Center and Units/Div. Y Center is the
centerline value of the chart when the channel is selected. Units/Div. is the vertical value of on chart
grid increment. When you change Y Center or Units/Div. Y Max and Y Min are automatically
adjusted. You can not directly adjust Y Max or Y Min while “Units/Div.” Is selected. You can change
Y Center and Units/Div. by using the up and down arrows, or by highlighting the existing value, typing
in the new value, the pressing “Enter” on your PC keyboard.

Note: If the window size is changed, a chart operating in the Units/Div. Mode will maintain its

units per division scale setting across the chart.

The channels in the display setup you create will be automatically enabled and will appear in chart
form on ChartView’s Main Window. The Channels will overlap on their assigned Chart (for
ChartView Plus applications), and will be visible when the applicable Group is selected. Note that
only one group of charts can be viewed at a time.

It is important to understand that other channels (those not in the display setup) maintain their existing
configuration status. They are not affected by the edit of the configuration display. You can enable
additional channels from the Channel and Alarm Setup window. Enabling additional channels allows
you to acquire more data; however, it will not change your display on ChartView’s Main Window. In
other words, you can also acquire data from channels which you do not monitor.

TempScan / MultiScan User's Manual Chapter 8: ChartView & ChartView Plus 65

Manually Creating a Display

For ChartView Plus users, if you plan to have a chart setup which is not weighted evenly, i.e., different
numbers of channels per chart and different numbers of charts per group, you may want to manually
setup your chart display from scratch, that is, without beginning from a pre-existing display
configuration. This method is arrived at from the Chart Setup Wizard window by selecting “Manual
Chart Creation.” When this button is clicked, the program exits the Chart Setup Wizard and enters the
manual method of Display Configuration Setup. Although this method is referred to as “manual,” it
still contains some automatic elements, such as Automatically Add Groups to the Setup (available with
ChartView Plus).

Note: Even if an unevenly distributed chart display is desired, you can always edit a pre-existing

chart setup, or create a new setup by one of the Chart Setup Wizard’s automatic methods, and
then edit the setup.

To manually setup your chart display, using the “clean slate” approach as opposed to “editing an
existing display,” perform the following steps.

1. Select Wizard from the Chart pull-down menu of ChartView’s main window. The New Display
Setup dialog box appears.

2. Click OK on the New Display Setup dialog box. The Wizard setup window appears (see following
figure)

3. Click on the Manual Chart Creation button. The Display Configuration Setup box appears. Since
the previous display configuration was reset, no groups or charts are seen in the display area on the
left side of the screen.

Note: If you have ChartView Plus, you will be allowed to have more than one group, as well as

overlapping channels (up to four per chart). If you have the basic ChartView program you
will be limited to one group, and only 1 channel per chart.

Display Configuration Setup, The “Clean Slate” Approach

66 Chapter 8: ChartView & ChartView Plus TempScan / MultiScan User's Manual

4. As seen in the previous figure for the “Clean Slate” approach, you have two options at this point.
Perform (4a) or (4b) as appropriate. With ChartView Plus, option (4a) is typically used.

(4a) Automatically add groups to the setup. Enter the number of groups and charts desired by using the cursor
and typing in the value, or by using the pull-down arrows (τ) and making the appropriate selections; then click
on the Create Groups button.

(4b) Manually add groups to the setup. Type in the name of the chart group; then click on the Add Display
Group button.

The Display Configuration Setup screen changes to show chart groups, and the number of charts

for the selected (black highlighted) chart group. From this screen you can change the number of
charts in a group, as well as change the group name.

Adding a Chart to Group 1

5. Change the number of charts per group if desired.

6. Change the group name if desired.

7. Click on a group to see the chart(s) assigned to the group. In the above example there is one group
with one chart.

8. Click on a chart to assign channels to the chart. A screen similar to the following will appear.

Assigning Channels to Chart 1 of Group 1

TempScan / MultiScan User's Manual Chapter 8: ChartView & ChartView Plus 67

9. Choose channels for the selected chart. With ChartView Plus you can select up to 4 overlapping
channels per chart. With the basic ChartView program you are limited to one channel per chart.
There are four methods of adding channels. These are as follows:

• Highlight an available channel using the cursor and left-hand mouse button; then click the Add button.

Repeat for each channel to be added.

• Double-click on the channel (in the available channels list to add; in the selected channels list to remove)

• Hold down the keyboard’s Shift Key and use the left-hand mouse button to select a block of consecutive

available channels (up to 4); then click the Add button. Example: CH3, CH4, CH5,CH6.

• Hold down the keyboard’s Ctrl button and use the left-hand mouse button to select up to 4 available

channels (these can be non-consecutive); then click the Add button.

• Example: CH1, CH3, CH5, CH7, as in the previous figure.

Note: You can also remove channels in a similar manner by highlighting a channel(s) in the

Select Channels box, and then clicking on the Remove button. In the previous figure,
CH7 (in the select box) is highlighted. Clicking the Remove button would delete that
channel from Chart1.

Note: When a chart contains overlapping channels and the channels share values such that their

traces reside on top of each other, then the channels that are listed lower in the display list
(the most recently added channels) will obscure the channels higher in the list (those
which were added first).

10. In the display area (on the left-hand side of the screen) click on a channel to check the channel’s
configuration and to re-configure the channel, if desired. The Display Configuration Setup
Window will appear similar to that in the following figure.

Note: Changing the display configuration does not change the existing channel and alarm

configuration. It only changes how the chart groups, charts, and channels will be
displayed.

This screen contains two “radio buttons” for selecting the method of adjusting the display mode
and channel setup. It is the same screen that was discussed in the sub-section, Editing an Existing
Display Configuration. From this screen you need to choose Units Full Scale or Units/Div. Each
method was previously discussed in the section Normal Edit on page 64.

Adjusting Channel Setup for Channel 1

68 Chapter 8: ChartView & ChartView Plus TempScan / MultiScan User's Manual

Remember, you can enable additional channels from the Channel and Alarm Setup window. Enabling
additional channels allows you to acquire more data; however, it will not change your display on
ChartView’s Main Window. In other words, you can acquire data from channels which you do not
monitor.

Channel Configuration

The “Channel Configuration” button brings up the Setup Window with one of three “tabbed” dialog
boxes displayed: Acquisition Setup (page 88), Channel & Alarm Setup (page 85), or Data Destination
(page 91). The information entered in the Acquisition Setup dialog box is used by the Arm Acquisition
command to set up the acquisition of data to disk. When the trigger is satisfied, the scans are collected
at the selected scan frequency and stored to disk in the designated file. The Channels & Alarms dialog
box is used to configure channels and alarms; the Data Destination dialog box is used to assign a
filename and folder location for data, select an Excel or binary format (
and to select optional Time/Date and/or Alarm Stamps (to be included in the data) if desired. You can
tab back and forth from each one of these dialog boxes to the other.

When ChartView is started for the very first time there is no default channel configuration file. In this
case a ChartView Startup dialog box appears, providing you with the following four choices: Retry,
Select Device, Load File, and Exit Program. After choosing Select Device a Select Interface dialog
box appears, allowing you to choose IEEE 488, RS-232, or Simulated Instrument.

After the selection has been made, when ChartView is shutdown, the selected interface device and all
channel configuration settings will be automatically saved in a default configuration file. Upon the
next start of ChartView, the default configuration is automatically loaded.

If the default configuration becomes corrupt, or if you would like to bypass the default configuration
when starting ChartView, you can hold down the Shift Key when starting ChartView. This causes the
program to ignore the default channel configuration settings and causes the ChartView Startup dialog
box to appear. This allows you to select Load File to make use of a specified channel configuration
file from a previously saved configuration.

of three options in regard to positioning data in Excel on subsequent scans. Options
are as follows:
Row 1 Column 1. This selection starts the next scan at the designated row and
column on the Excel spreadsheet. Changing the values in the “Row” and “Column”
boxes (above figure) will automatically enter the new values in the corresponding
fields of the “Row # Column #” placement assignment. For example, If you entered
a 3 in the row box and a 5 in the column box you would see Row 3 Column 5, instead
of Row 1 Column 1, in the above figure; and the next scan would start at row 3
column 5 in Excel.
Row after last scan. When “Row after last scan” is selected the next scan will begin
at the point in Excel where the previous acquisition left off.
Prompt each time. When “Prompt each time” is selected, after each acquisition is
completed a dialog box will ask if you want to return to origin. If you select “Yes”, you
will have an overwrite on the Excel spreadsheet, starting with the existing column and
row designation. If you select “No,” the next scan will begin on the spreadsheet’s
next row (from where the previous acquisition left off).

Increment the Row on each new scan. With this selected (9), the Excel
spreadsheet will use multiple rows, one row for each new data scan. With no
check-mark, the spreadsheet will make use of one row only and will continue to
display the latest scan information in that row.

This field allows you to enter a DDE link timeout value from 5 to 3276 seconds. The
value is how long the data import to Excel can be suspended while you perform a
second Excel activity, such as displaying graphs. A screen message informs you
when the DDE link is timed out, terminating the DDE link to Excel.

Brings up the Alarm Status box. The Alarm Status box shows the current state of each
alarm. The alarm state appears as either a “1” or “0”, the “1” being digital High, and the
“0” being digital Low (0). A one-for-one correlation between the alarm number and
channel can only occur if each channel of a 32 channel [or less] system is assigned to a
dedicated alarm number.

Alarm logging is a feature of ChartView Plus only. Alarm Logging allows you to
monitor the Alarm states of the instrument, and save selected information to a file
whenever any of the states change. Alarm logging is implemented by periodically
polling the instrument; the time interval between polls is about one second. With this in
mind you should note that any event that could trigger an alarm, that is one second or
less in duration, could be missed and not logged.

From the Alarm configuration dialog box you can define the information that will be saved
in the log file. Options include the Time and Date when the state change occurred, the
Alarm number, the Channel(s) that tripped the alarm along with the current reading, and
the state of the alarm itself or all alarms, either 1 or 0. Additionally you can define the
character that is used to separate the information in the file. This is useful if you want to
read the file into a program that presents the information in a tabular format, such as
Microsoft Excel.

By using combinations of option settings you can define how the alarm log file is filled. If
you choose not to save Alarm ID's (Alarm numbers) in combination with saving All Alarm
States, your Alarm file will be saved with one line of text each time an Alarm state change
is detected during polling. The line will contain the optional Time and Date and 32 digits,
one for each alarm, set to either 0 or 1. The left most digit being Alarm one, the
rightmost Alarm 32. Note that you can not choose to save Channel information if you
have selected not to save Alarm ID's. The following example shows what the Alarm log
entries look like if this configuration is selected:

If you choose to log Alarm ID's and multiple Alarm state changes are detected during a
single poll, multiple lines of text will be saved in the log file; one for each alarm that had a
state change. By examining the optional Time and Date information you can identify
which lines in the Alarm log are associated with Alarms that were detected during a

Setup Window

The Setup Window is used to configure channels, setup acquisition parameters, and assign data
destinations, and configure the auto re-arm feature. The Setup Window contains three tabs: Channel
and Alarm Setup, Acquisition Setup, and Data Destination. Once in the Setup window you can access
an inactive dialog box by clicking on its related tab. The three tabs remain visible, regardless of which
dialog box is currently active.

Access the Setup window using one of the following methods:

•

Use the Setup pull-down menu (on ChartView’s main window) and select the desired dialog box
(Channel and Alarm Setup, Acquisition Setup, or Data Destination)

• Double-click the Channel Configuration button (item 8, main window figure), then click on the

appropriate dialog box tab

Channel & Alarm Setup Dialog Box

The Channel and Alarm Setup dialog box consists primarily of a configuration spread-sheet. The
dialog box allows you to configure the input channels, and displays them. Each row shows a single
channel and its configuration. The number of rows may vary (depending on the number of channels
present in your acquisition system). Four of the columns (On, Type, Label, and Units) allow blocks of
cells to be selected and altered at the same time. Clicking on one of these column headers selects the
entire column.

When a cell is selected the message box reveals a note, and often a related pull-down list. In the
following figure, the cell for channel “Type” has been selected. This caused the “CHOOSE TYPE->”
message to appear, along with the type pull-down menu. Depending on the column, you can make
changes to the information contained in the cell by either of the following methods:

TempScan / MultiScan User's Manual Chapter 8: ChartView & ChartView Plus 85

• Double clicking the cell with the mouse

• Highlighting the cell and typing in the new value or label

• Selecting from a list

• Using copy (Ctrl+C) and paste (Ctrl+V) functions

Channel Configuration Columns

Channel (CH)

1.

 This column serves only as a channel number indicator. The channel number

cannot be changed from this column.

On

2.

 The On column allows you to enable a channel for data collection. When a cell or block of
cells in this column is selected, a selection box will appear that allows “On” to enable or “Off” to
disable the channel. Double-clicking a cell in this column toggles the channel’s enable status.
Clicking the Make All Channels Active button enables (turns all channels “on”). Clicking on the
Make All Channels Inactive button disables all channels (turns them “off”), with the exception
that channels assigned to charts can only be turned off from the display configuration setup.

3.

Readings

 The reading column displays the scanning device input readings. The column is
activated when you select the Enable SpreadSheet Reading button. The column’s values are real-
time channel values from the instrument and cannot be altered by the user. This column will
update the readings as fast as the computer will allow.

Note: Other areas of the SpreadSheet cannot be altered while the channel Readings column is

enabled.

4.

Type

 A block of cells in this column can be selected for convenience of single type selection.

Double-clicking a cell will select the next available type.

Label

5.

 The Label column identifies the input channel by descriptive name. The label is used
when selecting a channel in the trigger and chart selection lists. The label column automatically
uses the channel number as a default. You can change the label to any alpha-numeric designation
not exceeding eight characters. Each label used must be unique (specific) to its designated
channel.

6.

Units

 Cells in the Units column are dependent on the Type selected and automatically change
when the type is changed, for example temperature units will be replaced by volts units when
changing from a thermocouple type to a volts type.

If the channel is configured for Temperature the units automatically change to °C (default); at
this point, you have the option of selecting a different engineering temperature unit (°F, °K, °R).

Note that the mX+b equation, discussed in the following text, is typically not used for
temperature readings, since temperature data will be linear. However, you can use the

equation in temperature applications, for example: setting b to -32 in order to watch deviations
from freezing point when temperature is in °F.

In addition, with ChartView Plus you can subtract a reference channel from the mX+b equation to
obtain a temperature differential, as indicated in the following example.

Example:

A heated room has 2 thermocouples (T1 for CH1 and T2 for CH2); with T1 being in the center of
the room and T2 positioned at an outer wall. If the outer wall is monitored to ensure a temperature
within ±2°F (of the temperature indicated by thermocouple T1), then CH1 can be used as a
reference channel such that its value will be subtracted from the actual value for channel 2.
Assume the central thermocouple is reading 90.5°F and the outer thermocouple (for CH2) is
reading 89.0°F. In this case we can use the equation so channel 2’s charted reading will not be of
the actual temperature, but will be the differential between CH1 and CH2, e.g.:

y = (mX + b) - ref. chan

y

= Channel 2’s charted value (a temperature

differential)

m

= 1

b

= 0

X

= CH2

ref. Chan.

Channel 2’s charted value = (1 x CH2 + 0) - CH1
Channel 2’s charted value = (1 x 89.0°F + 0) - 90.5°F

Channel 2’s charted value = -1.5°F

= CH1

; where:

Note: The reference channel feature is only available with ChartView Plus.

TempScan / MultiScan User's Manual Chapter 8: ChartView & ChartView Plus 87

Note: When using a channel as a reference channel, remember that lower numbered channels

are calculated ahead of higher numbered channels, e.g., CH1 is calculated ahead of CH2.
This makes a difference when subtracting a reference channel in regard to the time aspect
of the reference value.

If the channel is configured for Volts, the units automatically change to V; at this point you have
the option of selecting the millivolt unit (mV). The user can also change each channel to apply a
linear equation (mX+b) to the data. When the mX+b option is selected the Configure Engineering
Units dialog box is displayed. You are prompted to define “m” and “b” and the engineering units
label; as well as which standard units the mX+b equation should be applied to. The engineering
units chosen will be displayed in the “Units” column, and the “mX+b” equation will be applied to
the reading from the device before the reading is displayed or written to disk.

The mX+b option is convenient for obtaining a value which has a linear relation to a channel
reading.

X is the scanned voltage value read back from the acquisition device
m is [but not limited to] a proportionality constant or gain factor, but not zero.
b is the offset value (the value of the calculated reading when the scanned value is “zero”).
