LIMITED WARRANTY AND LIMITATION OF LIABILITY

Each Fluke product is warranted to be free from defects in material and workmanship under normal use and
service. The warranty period is one year and begins on the date of shipment. Parts, product repairs, and
services are warranted for 90 days. This warranty extends only to the original buyer or end-user customer of
a Fluke authorized reseller, and does not apply to fuses, disposable batteries, or to any product which, in
Fluke's opinion, has been misused, altered, neglected, contaminated, or damaged by accident or abnormal
conditions of operation or handling. Fluke warrants that software will operate substantially in accordance
with its functional specifications for 90 days and that it has been properly recorded on non-defective media.
Fluke does not warrant that software will be error free or operate without interruption.

Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers
only but have no authority to extend a greater or different warranty on behalf of Fluke. Warranty support is
available only if product is purchased through a Fluke authorized sales outlet or Buyer has paid the
applicable international price. Fluke reserves the right to invoice Buyer for importation costs of
repair/replacement parts when product purchased in one country is submitted for repair in another country.

Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair,
or replacement of a defective product which is returned to a Fluke authorized service center within the
warranty period.

To obtain warranty service, contact your nearest Fluke authorized service center to obtain return
authorization information, then send the product to that service center, with a description of the difficulty,
postage and insurance prepaid (FOB Destination). Fluke assumes no risk for damage in transit. Following
warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke
determines that failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal
condition of operation or handling, including overvoltage failures caused by use outside the product’s
specified rating, or normal wear and tear of mechanical components, Fluke will provide an estimate of repair
costs and obtain authorization before commencing the work. Following repair, the product will be returned to
the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges
(FOB Shipping Point).

THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY
OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE
FOR ANY SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OR LOSSES,
INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR THEORY.

Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or
limitation of incidental or consequential damages, the limitations and exclusions of this warranty may not
apply to every buyer. If any provision of this Warranty is held invalid or unenforceable by a court or other
decision-maker of competent jurisdiction, such holding will not affect the validity or enforceability of any other
provision.

Product Overview and Specifications

Introduction 1

Introduction

This chapter supplies information about the Product, the manual set, safety information,
contact information, and specifications.

Product Overview

The Fluke Calibration 1586A SUPER-DAQ Precision Temperature Scanner (the Product
or Instrument) is a 45 analog channel bench-top measurement instrument that measures
and records temperature, resistance, dc volts, and dc current (see Table 1-1). See the
Specifications section for information on the types and ranges of the measurement inputs
the Product can accept.

Features of the Product include:

Temperature Accuracy – Measures temperature with uncertainty as low as 0.01 °C

•

with a PRT, 0.003 °C with a thermistor, or 0.2 °C with a thermocouple. PRT
accuracy is enhanced by 4-wire sensing that cancels out lead-wire resistance,
bidirectional source current that cancels thermoelectric EMF in the PRT, and ITS-90
characterization that accurately relates resistance to temperature.

•

Scan – Sequentially scan up to 45 analog channels per scan sweep. In addition, the

Product also has 20 math channels, one DIO channel, and one TOT channel that can
be included in scan. A scan can be manually controlled from the front panel or
triggered with a variety of triggers such a timer, an alarm, an external source, or a
remote SCPI command.

While a scan is in progress, all channel values can be viewed on the display in a
spreadsheet format along with statistics such as average, standard deviation,
minimum, maximum, peak-to-peak, and rate-of-change. With the Graph feature,
channel measurement data for up to four channels can be plotted and viewed on the
display. Users can toggle the data mode with a softkey to view live data or historical
data.

•

Monitor – View the measurement value or the statistics of a single channel. Monitor

is an independent feature that can be used while a scan is in progress or inactive.
Much like the Scan feature, the statistics of the single measurement can be viewed on
the display or be shown in a graph.

Digital Multimeter Functionality (DMM) – Function that presents the user with

•

familiar DMM features and controls like a standard bench DMM. The DMM can
show 6 ½ digits on the display. To visualize trend data, the DMM provides additional
functionality to graph and see measurement statistics.

Users Manual

• Data Storage - Store up to 20 MB of data and channel setup files directly to the

internal non-volatile memory or an external USB drive. Data can also be transferred
to a PC with a USB drive or LAN TCP/IP interface at the rear of the unit with SCPI
interface command sets.

•

Alarms – Each channel can be assigned two independent alarms to indicate when

either an upper (HI) or lower (LO) range has been exceeded. The alarms can be
configured to output a digital signal from the rear-panel alarm output for control of
external devices.

Digital I/O (DIO) – The Product is equipped with a digital 8-bit transistor-transistor

•

logic (TTL) port that can sense and output. When the DIO channel is included in the
scan list, the value of this port is recorded in the scan data record on each scan with a
value range of 0 to 255 based on the port state when it is read.

•

Totalizer – The Product is equipped with a unidirectional, resettable totalizer with an

input count capability of 1,048,575 (20 bits). Counter increment is accomplished
through a change to a digital signal or contact closure to the totalizer input terminals
on the rear of the Instrument.

Remote Operation – Remotely operate the Product with remote SCPI commands

•

from application software over a rear-panel USB or LAN TCP/IP connection.

•

Automated Sensor Test – Automatically sets the temperature of a Fluke

Calibration dry-well calibrator or temperature bath connected to the rear-panel
RS-232 port. Monitors temperature stability, and measures the readings of
temperature sensors and a reference thermometer when the temperature is stable.

DAQ-STAQ Accessory – Multiplexer module provides quick and convenient

•

connection of temperature sensors with Fluke's patented spring-loaded DWF
terminals.

PRT/RTD Resistance Accuracy

Accuracy is given as ± (% of measurement + ohms). Basic accuracy is for 4-wire PRT/RTD using medium or slow sample
rate. When using 3-wire PRT/RTD add 0.013 Ω to the accuracy specification for internal resistance mismatch and voltage
offset if using Channel 1, or add 0.05 Ω if using channels x01 through x20. When using Fast sample rate add the number
given in the table to the accuracy specification. The 4 kΩ range accuracy specification can be decreased by 0.06 Ω if
using Slow sample rate. If the environment temperature is outside the specified range, multiply the temperature coefficient
numbers by the temperature deviation and add to the accuracy specification.

configure the associated channel.

Input Wiring

The 1586-2586 High Capacity Input Module

The 1586-2586 High Capacity Input Module (the Input Module) is used to wire inputs of
various types to the Product (see Figure 3-1). Each Input Module has 20 analog channels
(ChX01 through ChX20) that can be configured to measure temperature, resistance, and
dc volts and two low-burden current channels (ChX21 and ChX22) that measure
dc current without the use of an external shunt resistor.

Note

To expand the functionality of the Product, current sources can also be connected
to channels ChX01 through ChX20 by the use of an accessory shunt resistor. See
Chapter 6 for part number and ordering information.

Wiring Safety and Considerations

Warning

To prevent possible electrical shock, fire, or personal injury:

• Consider all accessible channels to be hazardous live and an

electric shock hazard if any channel is connected to a
hazardous voltage source.

• Do not remove, touch, or change the internal wiring of

hazardous inputs until the input source is turned off.

• Remove inputs from hazardous voltage sources before an

input module is opened.

• Use the correct terminals, function, and range for

measurements.

• Make sure proper insulation is maintained between channel

wiring terminations and that no loose strands are outside of
the terminal block connections.

Caution

To prevent damage to the Product, do not exceed the specified
input voltage levels.

Shielded wires and sensors (such as thermocouples) should be used in environments
where "noisy" voltage sources are present. When shielded wiring is used, the shield is
normally connected to the L (low) input terminals for each channel. Alternate
configurations should be examined for each equipment application.

3-Wire and 4-Wire Sense Input Configuration

For improved resistance measurement accuracy, the Product can connect to 3-wire (PRT
only) and 4-wire instruments with sense connections.

Sense connections cancel out the resistance of the test lead or wire and significantly
improves the accuracy of the measurement. As shown in Table 3-1, many thermistors,
platinum-resistance thermometers (PRTs) and resistors use a 3-wire or 4-wire sense
connection to eliminate lead wire resistance errors.

For 2-wire measurements, the wires can be connected to either the source or sense
channels ChX01 through ChX20. For 3-wire or 4-wire resistance measurements, the
source wires must be connected to channels ChX01 through ChX10 and the sense wires
to the set of terminals directly across from where the source is connected (channels
ChX11 through ChX20).

Note

The Product will not show or let the user select a 3-wire or 4-wire input on
channels ChX11 through ChX20.

Figure 3-3 shows an example of a 4-wire input (PRT) with sense wires connected to the
Input Module, then how it would look in the Channel Setup menu once it is properly
configured.

To use the sense connections, the channel connected to the source wires must be
configured as a 3-wire or 4-wire input as described in “Channel Configuration
Procedures” on page 3-10. When a channel is configured as a 3-wire or 4-wire input, the
Product automatically reserves the sense channel across from the source that prevents the
channel from being independently configured, as shown in Figure 3-3.

Channel Configuration

This section contains instructions on how to configure the channels after the inputs are
connected to the Input Module.

About Channel Numbers

A channel number (Ch) is a numerical identification associated with a set of terminals on
the Input Module. The channel number of the input is determined by the slot number the
Input Module is in (1 or 2) followed by the number of the terminal the input is connected
to (1 to 22) as illustrated in Figure 3-5. The front-panel inputs are permanently assigned
to channel Ch001. Here are some examples on how to determine the channel number of
an input:

• A voltage source is connected to input terminal 4 (04) in the Input Module and then

slid into slot 1. The channel is Ch104.

• A thermistor source is connected to input terminal 8 (08) in the Input Module and then

slid into slot 2. The channel is Ch208.

• A voltage source is connected to the front-panel terminals. The channel is Ch001.

Table 3-2 shows channel types and channel numbers.

Users Manual

The display opens a channel configuration sequence that prompts the user to select key
parameters for the specific channel type. These sequences are shown and described in the
analog channel configuration section that starts on page 3-18.

Note

If the configuration sequence is skipped or stopped before the sequence is
complete, the default channel settings are used for the skipped steps. Some
channel settings are not able to be configured or changed outside of the
setup sequence.

Use the  or  to select the settings and input values with the numeric keypad. Once a
parameter is set, push  to save the setting.

Verify a Channel

After a channel is set to ON and configured, a direct measurement can be made to verify
that the channel is configured properly.

To verify a channel:

1. Turn on the input source that is connected to the Product.

2. Push .

3. Push  or  to highlight a channel.

4. Set the channel to

5. Push  to edit the channel.

6. Push  to open the Verify Channel menu.

7. Evaluate the measurement and zero the channel if necessary. See “Zero a Channel”.

Zero a Channel

In certain applications, it may be necessary to zero the channel in order to make
measurements without unwanted offsets or noise levels. The zero channel function is
located in the Verify Channel menu that is accessed by a softkey in the Channel Setup
menu. The Product uses the Mx+B offset value to zero a channel. To do this, the Product
calculates the offset required to convert the measurement to a zero value, sets Mx+B to
ON, and loads the calculated offset value into the Mx+B settings. To clear the zero, the
offset value can be manually set back to the original value (usually “0”) or Mx+B can be
set to OFF if it was off before the channel was zeroed. Zero offset values can be viewed
in the setup file associated with the scan data file (see Chapter 4).

When a zero is performed, the Product will overwrite any custom offset
values in the Mx+B settings. If a channel has a custom Mx+B offset, make
note of the offset value before the channel is zeroed so it can be referred to
later if necessary.

To zero a channel:

Digital I/O (DIO) Channel Configuration (Ch401)

The Product can sense and output a digital, 8-bit transistor-transistor logic (TTL) value
that can be displayed as the 8-bit TTL value and be recorded as the decimal equivalent.
This is accomplished with the rear-panel digital I/O connectors (DIO) that are shown in
Figure 3-8.

When a DIO input is sensed, the Product displays the status of the digital I/O as 8-bit
TTL value and records the decimal equivalent. The 8-bit TTL value can also be seen
when a channel is monitored. The default value is a high state that shows as “11111111”
until the Product senses a low state or is used as an output. A few examples of some 8-bit
TTL values and their decimal equivalents are shown below:

• 11111111 is represented by decimal 255

• 00001111 is represented by decimal 15

• 00010001 is represented by decimal 17

• 10000101 is represented by decimal 133

Notes

For input and output specifications such as input and output voltages, see
“Digital I/O” in Chapter 1.

The DIO channel will be read-only when it is set to ON (active).

With a remote command, the Product can output an 8-bit TTL value. See the
1586A Remote Programmers Guide for more information.

Totalizer Channel Configuration (Ch402)

The Product is equipped with a unidirectional, resettable totalizer with an input count
capability of 0 to 1048575 (20 bits). When a digital input is connected to the TOT input
on the rear panel and Ch402 is set to on, the Product counts each time the dc voltage of
the signal transitions from high to low or a contact closes to the ground (GND). When a
scan is started, the TOT counter is reset to 0. The totalizer count can be manually reset at
any time with  in the Scan menu.

Read Mode

The totalizer function has two read modes: read and read/reset. The mode can be set in
Channel Setup or by remote command. The default totalizer mode is read.

In read mode, the count is not effected when read during the scan sweep or read by
remote command.

In read/reset mode, the totalizer count is automatically reset to 0 when it is read during a
scan sweep or read by remote command. It is not effected by pause scan. The totalizer
count is not reset when it is viewed with the Monitor function.

Debounce

In some applications, contacts can “bounce” when they close that results in multiple
signals on one line. Without a filter the Product detects multiple closures that can cause
duplicate counts for one closure. To filter the signal, the Product has a debounce feature
that can detect bounce on the signal and ignore it. Debounce (600 Hz) can be turned on
with the Edit channel function of the Totalizer channel (Ch402). If the debounce feature
is disabled, 10 kHz is the maximum frequency the Totalizer input can support.

Channel Configuration 3

Math Channel Configuration (Ch501 to Ch520)

The Product has 20 math channels that lets the user apply a math conversion to a single
channel or to a range of channels through the use of preset math functions. Table 3-10
lists the math functions available for use.

Math channels are commonly used to combine the measurement values then display them
as one number without the need to manually calculate the values. Like all other channels,
math channels can be scanned and recorded.

Another use of the math channels is to apply a math conversion to a single channel that is
more advanced than Mx+B scaling. For example, a more accurate conversion of an
output of a transducer to a physical parameter.

More complicated expressions can be made with a math channel that uses the
calculations from two other math channels. For example, a math channel could be
configured to calculate the exponential function of another math channel that is
configured to calculate a polynomial function of an input channel.

value to a positive number if it happens to be negative.
The absolute value function can be useful to ensure that
the argument to another math channel is always positive.

Mx+B, Alarms, and Channel Options

The subsequent sections supply information and procedures on how to apply Mx+B
scaling, set up channel alarms, and configure additional channel options.

Mx+B Scaling

Mx+B is a calculation that can be applied to a channel to scale a measurement value. This
feature is useful in applications where an input measurement needs to be converted to a
different unit or value to simulate an output. Common scaling conversions are:

• Scaling of a milliamp output of a pressure transducer to the equivalent kPa or psi
value.

• Scaling of a temperature reading from degrees Celsius to kelvins.

• Conversion of shunt resistor voltage to current in amperes.

To calculate Mx+B, the "M" value is referred to as the “gain” and is used as a multiplier
of the actual reading. After the gain is calculated, the "B" value or the “offset” is added to
the resultant.

For example, if a channel measures a voltage of 3 volts and the gain was set to 3.3, the
measurement on the display would read 9.9 volts (3 V * 3.3 gain = 9.9 V). Now the offset
is added to the gain. If the offset was set to 11.0, it would be added to the 9.9 volts and
the display would read 20.9 volts (9.9 V + 11.0 offset = 20.9 V).

More examples:

(6.9 gain * 20 mA) + 16.0 offset = 154 kPa
(1.0 gain * 25.0 °C) + 273.15 offset = 298.15 K
(10.0 gain * 0.32 V) + 0.0 offset = 3.2 A

If necessary, the Mx+B menu lets the user designate a new unit to accurately represent
the scaled measurement. This unit shows on the display and in the recorded scan data as
long as Mx+B is set to ON. If the Mx+B is set to OFF, the unit reverts back to the
original unit. When a channel has Mx+B scaling applied, a [Mx+B] icon is shown above
the unit next to the measurement value.

Note

If the scaled value is too large, "OL" (overload) is displayed. Adjust the
gain or the offset and try again.

Input and Channel Configuration

Mx+B, Alarms, and Channel Options 3

The Product uses the offset to zero a channel. To do this, the Product calculates the offset
required to convert the measurement to a zero value, sets Mx+B to ON, and loads the
calculated offset value into the Mx+B settings. To clear the zero, the offset value can be
manually set back to the original value (usually “0”) or Mx+B can be set to OFF if it was
off before the channel was zeroed. See “Zero a Channel” on page 3-14 for instructions on
how to zero a channel.

To apply an Mx+B scaling to a channel:

1. Push .

2. Push  or  to highlight a channel.

3. Set the channel to

ON if necessary.

4. Push  to edit the channel.

5. Select Mx+B and push .

6. Input the Gain and Offset values and set the unit as desired. When complete, push
 to return to the previous menu.

7. Verify the channel. If the scaled channel gives unexpected results (like zero or
“OL”):

• Verify that the correct gain and offset values are set.

• Manually calculate the result with the entered gain and offset values. See the

examples in this section.

• Temporarily set the gain to 1 and the offset to 0 to verify that the measurements

are in the expected range. Unexpected measurements could result from a wiring
error or the wrong range or function selected.

HI and LO Channel Alarms

Each channel has two channel alarms that can have custom values assigned to trip when a
channel measurement exceeds the assigned high (HI) or low (LO) limit. If an alarm trips,
the measurement value on the display changes to red and will stay red until the
measurement is back in the normal range.

In addition to the visual indication, the channel alarm can be tied to one of the six alarm
outputs on the rear panel (see Figure 3-10 and Figure 3-11). An alarm output can have
multiple channels assigned to it. If an alarm trips, the alarm outputs a low condition
signal (<0.7 V dc). A common use of this feature is to connect to an external audio alarm
that will sound if the channel alarm is tripped.

Channel Delay

A channel delay is a measurement time delay that can be individually assigned to each
channel to delay the measurement. Channel delays can be used for various applications,
but they are most useful in applications where the source impedance or circuit
capacitance is high. Use of a channel delay in these applications allow the input signal to
settle before a measurement is made. This provides better measurement accuracy.

When a channel delay is set, the Product inserts the delay after the channel relays switch
and waits until the channel delay time runs out before it measures the channel. Channel
delays are set in seconds and the default setting is 0 seconds.

To set a channel delay:

1. Push

2. Push  or  to highlight a channel then push .

3. Push  to open the Channel Options menu.

4. Select

5. Set the custom channel delay. The delay can be manually set in 1 millisecond
increments from 1 millisecond to 600 seconds.

Rate of Change

Rate of Change is a statistical calculation that shows the user how much a measurement
value has changed over a period of time. The Rate of Change is viewed in the
statistics/graphing area in the Scan Menu. The Rate of Change setting in the Channel
Options menu sets the scaling to per second (/s) or per minute (/min).

Per minute (/min) is the default scaling selection unless otherwise changed.

To determine the rate of change, the Product compares two readings of a channel
sampled at different times. First, the product computes the difference between the two
readings and then divides it by the time difference between the samples in seconds. The
result is then multiplied by the time base in seconds (60 for per minute) to determine the
Rate of Change.

If a channel is sampled more frequently than once every 10 seconds, two
readings about 10 seconds apart are selected. If the interval between
readings is 10 seconds or longer, the latest two readings are used.

Scan/Monitor, Record, and Data

Introduction 4

Introduction

This chapter supplies information on the Scan, Monitor, and Record functions along with
procedures and instructions.

Scan

Scan is a function of the Product that sequentially measures each channel and either
temporarily shows the data on the display or records it to file if the recording feature is
enabled (see “Record” on page 4-16). Scans are started manually by the user or by an
internal or external trigger. To scan a channel, the Product sequentially cycles through the
channels that are active and makes measurements as directed by the Test Setup file (see
“Configure a Scan” on page 4-6).

Note

Monitor is a function to see the measurement data from a single channel
while a scan is in progress (see “Monitor” on page 4-15). Use of the
monitor function does not interrupt the active scan and only shows the
measurement data from the last scan cycle completed.

In order for the Product to scan, the applicable channels need to be active and the unit
under test (UUT) must be connected and ready. After these steps are complete, a scan can
be started from the Scan/Monitor menu. If “Auto Recording” in the Test Setup menu is
set to ON, the Product automatically records the scan data when the scan is started. If set
to OFF, the user must manually push the Record key () to record the measurement
data to file. The scan data is stored to memory where it can be transferred to a PC to be
viewed with Microsoft Excel (see “Open and View Measurement Data on a PC” on
page 4-20).

While a scan is in progress, the measurements and statistics for all channels can be
viewed in a chart or in a graph without interruption to the scan (see Figure 4-4). After a
scan is stopped, this scan data stays in temporary memory and remains available until a
new scan is started.

 Start or stop a scan. See “Start a Scan” on page 4-11.

About Scan Timing and Sampling

When a scan is started, the Product sequentially scans and measures (samples) each
active channel in ascending channel order. How long it takes to sample a channel
depends on the measurement function, the user-programmed channel delay, and the
sample rate of the scan. Collectively, the sum of channel sample times determine how
long it takes to complete a full scan cycle and is referred to as the sweep time. See
Figure 4-2 for an illustration of how the scan process works.

The channel sample times and scan sweep times vary based on the channel and test
settings. The items below provide information on how these times can be impacted:

• The minimum channel sample time depends on the sample rate setting and the

• The total channel sample time is the minimum sample time plus the user-

programmed channel delay. The longer the channel delay, the longer it takes to
sample the channel.

• The total scan sweep time is sum of the channel sample times of all the channels

scanned. A scan sweep will start when the selected trigger source is asserted if a
previous scan sweep is not still in progress (see "Trigger Type" on page 4-7).

• The interval at which scan sweeps occur can be fixed by programming the trigger

type to Timer and setting an interval time.

Data Security

Data security is used to secure data files that are traceable back to the user that performed
the test (commonly referred to as test traceability). This is necessary for test
environments and applications that require a method to guarantee that the test data has
not been forged, changed, or tampered with, and was produced by trained, authorized
personnel.

If the data security setting in the Test Setup menu is set to ON, the user must select a user
profile and enter the associated password in order to start and record a scan. The user
information is recorded into the scan data file that contains the user profile number and
test information. For more information on the scan data files, see “Record” on page 4-16.
For instructions on how to change the Admin or User profile passwords, see “Change the
Admin and User Passwords” in Chapter 2.

When Data Security is on, Setup files are also protected. A setup file created with Data
Security on cannot be changed or deleted except by an authorized user.

Note

If the guest option is used to start a scan, the user is recorded as "Guest"
and the data file is not considered authorized and traceable.

Temperature Unit

This is an overall Product setting that sets the temperature units to be shown in either
Celsius or Fahrenheit.

Notes

• The ability to change this setting to Fahrenheit is not available in

some regions.

• Mx+B and Alarm settings of temperature channels are reset when the

temperature unit is changed.

Align Channels

The Align Channels function lets the user designate a reference channel to align other
channels to so that measured offsets between sensors can be set to zero relative to one
another and the reference channel. This is accomplished with an Mx+B offset that is
automatically applied to the selected channels to make them match the reference channel.

An application where this is commonly used is for temperature measurements. For
example, a reference probe that is fully calibrated is put into a chamber with other probes
that reads 250.52 °C. With the align function, the user sets the calibrated reference probe
channel to be the reference channel. The user then sets four probes channels to be aligned
with that reference that currently read 250.52 °C, 250.68 °C, 250.71 °C, 250.33 °C. When
the user aligns the probes, the Product calculates and applies an Mx+B offset to the
probes so that the displayed measurement value is the same as the reference probe. The
result is that all four probes now measure 250.52 °C.

Automated Test

Overview

The Product has an automated test feature that works directly with an external
temperature source (the source) to calibrate and verify the performance of temperature
probes (UUT) against a calibrated reference probe.

To fully automate the test, the user can connect to and control a temperature source such
as dry-wells, microbaths, or fluid baths from Fluke Calibration. In this configuration, the
Product communicates the setpoint to the source via the RS-232 connection on the rear
panel (see Figure 4-7). The source is then activated and sets the temperature to the
setpoint. When the measurement from the reference temperature probe that is wired to the
Product meets all the parameters of the setpoint (tolerance, stability, and soak time), the
Product automatically communicates the next setpoint. This sequence repeats until all
setpoints are complete.

Note

The Automated Test has a Control Source setting that can be toggled to On
or Off. When Off, the operator must manually set the temperature on the
source.

Record 4

Record

The Record function saves the scan or DMM measurement results to a file that can be
transferred to a PC for further evaluation. When the Product is recording data, the

Record key is illuminated and “RECORDING” shows on the top of the display. Data is

recorded for as long as the key is illuminated and “RECORDING” shows on the display.

Note

Scans can be completed without recording the results. In this scenario, the
data is saved to temporary memory and will be overwritten the next time a
scan is started or if the temporary memory becomes full (approximately
60,000 readings).

Record Measurement Data

For the Scan function, the behavior of the Record key is dependent on the Auto
Recording setting in the Test Setup menu. If set to ON, the Product automatically records
the scan data when the scan is started. If set to OFF, the user must manually push
to record scan data to file after the scan is started.

Note

Auto Recording is associated only with the Scan/Monitor function and does
not work with the Measure/DMM function. To record a measurement, push
 to start recording DMM or Measure data regardless of the Auto
Recording setting in the Test Setup menu.



Each time data is recorded, a new data folder is made with a unique timestamp so that it
can be easily found and managed (see “Open a Data File on a PC”). Data files made from
a scan are saved in the “scan” folder, DMM data files are saved in the “dmm” folder and,
Measure data files are saved in the “meas” folder.
