User’s Guide

4.4.1 Using the Clamp-on Ferrites

Clamp-on ferrites are provided with this product for the use of improving its electromagnetic (EM) immunity in environments of excessive EM interference. During EMC testing we found that ferrites clamped around the probe cables and power cord reduced the risk that EM interference affects measurements. Therefore, we recommend that the clamp-on ferrites provided (Steward P/N 28A2025-0A2) be used on the cables of probes attached to this product, espe cially if it the product is used near sources of EM interference such as heavy in dustrial equipment.

To attach a ferrite to a probe cable, make a loop in the cable near the connector and clamp the ferrite around half of the loop as shown in Figure 1. The ferrite can be easily snapped open and moved to a new probe when needed.

4.5 Connect the Power Source

The 1529 draws power from either a 15-volt DC power supply (the included AC adapter) connected to the DC input or the internal re-chargeable battery pack. To use the AC adapter, plug it into a wall outlet of the appropriate voltage and insert the DC plug into the DC power input of the 1529 (see Figure 3 on page 16.)

4.6 Switch the Power On

Power is turned on and off with the power switch located on the top right cor ner of the back panel. To switch the power on, toggle the power switch to the ‘ON’ position. To switch power off, toggle the power switch to the ‘OFF’ posi tion. The instrument takes a few seconds to power up, initialize, and begin nor mal operation. A self-test is performed displaying the channel configuration and status of the system, calibration, GPIB, memory, and buttons. If the ther mometer readout calibration has expired, the user is notified and must press the

Page 22

Enter button to continue initialization. If an error message is displayed on power up see Section 11.1, Troubleshooting.

4.7 Measure Temperature

After initialization, the temperature measurements for the configured channels are displayed. The appropriate sensor type must be selected and coefficients en tered for the measurements to be accurate (see Section 7.2.1, Edit Probe). Place the sensors of the probe into the object(s) you want to measure. DO NOT force the probe(s) or otherwise allow them to be bent, stressed, or overheated. Probes can be easily damaged if misused. For further suggestions on handling the probe and using the 1529 and probe to measure temperature accurately, see Section 6, General Operation.

6 General Operation

Display

This section explains basic operation of the 1529 thermometer readout. De tailed operation of the 1529 is explained in Sections 7 and 8. Section 7 explains the menu structure and the functions available in the menu structure and Sec tion 8 explains the communications interface for operating the 1529 remotely.

6.1 Display

The 1529 display consists of two parts. The top portion of the display is used for displaying the measurements from one to four inputs. The bottom portion of the display is reserved for the programmable fields and field display sets. Infor mation about the channels and measurements can be displayed in greater detail such as min, max, spread, standard deviation, and many other functions. When the measure period is 0.1 or 0.2 seconds (fast measurement mode), the pro grammable fields and field display set information are not displayed.

6.2 Changing Units

The 1529 thermometer readout is capable of displaying temperature in Celsius (C), Fahrenheit (F), or Kelvin (K). (Displaying in units of Ω,KΩ,ormVisalso

available through the PROBE menu and is channel specific.) Temperature units are changed on all channels (not individually) by pressing the buttons on the

front panel when not in the menu structure. Press the Unit, LR, buttons to scroll forward and backward through C, F, or K. All channels or fields that are displaying temperature on the upper or lower display are updated to the new units.

Channels that are set to Ω,KΩ, or mV in the PROBE menu are left unchanged when temperature units are modified. Changing the units resets the statistical calculations (displayed in the bottom portion of the display).

6.3 Battery

The 1529 thermometer readout has a built-in nickel-metal-hydride battery pack that can power the instrument for about eight hours before needing to be re charged. The battery discharges more quickly when the display backlight is used. The percent of battery charge remaining is displayed on the bottom por tion of the display when the battery power is being used. The battery percent age is approximate and should only be used as a general guideline when determining the length of charge remaining. The battery is recharged in situ (while in place) using the AC adapter that is provided.

Plug the AC adapter into the wall outlet and connect the DC plug of the adapter into the 1529. The battery is charged as necessary whether or not the instru ment is switched on. The power control circuit inside the instrument manages battery charging and stops charging the battery automatically when the battery

Page 27

1529 Chub-E4 Thermometer Readout

User’s Guide

is fully charged. Only charge the battery when ambient temperature is between 16°C and 30°C (61°F and 86°F) It normally takes about three hours to fully charge the battery. The instrument can be operated while the battery is being charged. The charging indicator on the back panel is green when the battery is fully charged and amber when being charged using the AC adapter.

The battery may self-discharge over several months, especially if the tempera ture is warm. The battery pack can be used for a minimum of 500 charge-dis charge cycles before needing to be replaced. Replacement battery packs are available from the manufacturer. The battery pack can be easily removed and replaced in the field by following this procedure:

1. Power the 1529 off and unplug the AC adapter from the unit.

2. Turn the 1529 over to expose the battery compartment. Remove the bat tery cover hex screw. Place the screw in a safe place so it won’t get lost. Flip open the battery cover to reach the battery pack.

3. Remove the battery pack. Gently disconnect the battery plug connector.

4. Attach the polarized plug of the new battery pack onto the connector. Note: The battery plug is polarized and can only be plugged in one direction. DO NOT force it. Place the battery pack in the battery compartment.

5. Close the battery cover and replace the screw. Avoid pinching the battery wires.

6. Plug in the AC adapter and charge for a minimum of four hours for the initial charge. Used batteries must be disposed of properly. Check your local regulations for additional information. You may return used batteries to the manufacturer. Never dispose of batteries in fire as this may result in an explosion with the possibility of personal injury or property damage.

When the battery charge is not at 100%, the measurement accuracy is not af fected. If the power is interrupted while the instrument is logging measure ments (on demand or automatically), the logged data is preserved and logging resumes when the power is restored.

6.4 Probe Input Modules

The 1529 can be configured in three ways:

•

Two RTD/thermistor input modules.

•

Two thermocouple input modules.

•

One RTD/thermistor and one thermocouple input module.

Each input module supports two channels. Your 1529 thermometer readout is configured at the factory and is not field changeable. Input modules should never be removed for any reason.

Page 28

All possible configurations are shown in Figure 3 on page 16.

6.4.1 Connecting a PRT or Thermistor Probe

PRT and thermistor probes are attached to the resistance input module via Hart Scientific mini-DWF connectors. These patented connectors accept bare wire, spade, or mini banana plug terminations. The connectors are color coded for ease in connecting lead-wires.

When using 2- and 3-wire sensors, the accuracy of the 1529 is reduced as stated in the specifications. Compensation is made for 3-wire PRTs, but the dif ference in lead resistance affects the measurement accuracy. The 1529 ther mometer readout is unable to compensate for 2-wire lead resistance.

Attach the lead-wires of the probes as shown in Figure 5 on page 22. The top termainals sense current and the bottom terminals sense potential.

6.4.2 Connecting a Thermocouple

The 1529 thermocouple input module accepts both standard and sub-miniature size thermocouple connectors. The connection is made with the positive terminal on the right and the negative terminal on the left. You must use a connector that matches the thermocouple type for the internal RJC to be accurate. For example, if you are using a type K thermocouple you must also use a type K connector, which is made from the same type of metal. For best results, wait two minutes before measuring after inserting the thermocouple connector into the input module.

6.5 DC Power Source

Caution: For CE compliance and for performance, use only the AC

adapter shipped with the instrument by Hart Scientific. If the AC adapter needs to be replaced, contact an Authorized Service Center (see Section

1.3).

The DC power source provides power to charge the battery. It can also be used to power the 1529 while the battery is being charged. The AC adapter provided with the 1529 is intended for these purposes. The DC power source plugs into the DC power input on the back panel of the instrument. The AC adapter has circuits with high voltages inside that could present danger of electric shock or fire if exposed. If the AC adapter is damaged in any way or becomes hot, dis continue use immediately, disconnect the adapter from any AC supply, and re place the adapter. Do not attempt to open, repair, or continue using a damaged or defective AC adapter.

6.6 Power On Self-Test

When power is turned on, the 1529 performs a self-test checking the system, all channels, calibration, GPIB, memory, and buttons. If an error occurs, an error message is displayed. See Section 11.1, Troubleshooting for additional information on error messages.

6.7 Display Backlight and Contrast

The display backlight is adjustable for use in varying lighting conditions. The four backlight modes are accessible in the CHANNEL menu DISPLAY OP TIONS function. If the display appears faded, dark, or blank, adjust the con trast (off, low, medium, high) using the front panel contrast buttons.

6.8 Taking Measurements

The procedure for configuring the 1529 thermometer readout to take measure ments on a particular input channel requires the following: (1) connecting the sensor to the appropriate input channel , (2) enabling the channel, and (3) se lecting the conversion type and probe characterization values.

6.8.1 Connecting the Sensor

Connect the sensor to the RTD/Thermistor channel(s) or thermocouple chan nel(s) that you want to measure. Refer to Section 7.4, Probe Input Modules, for additional information.

Page 31

1529 Chub-E4 Thermometer Readout

User’s Guide

6.8.2 Enabling the Channel

Channels are set first by selecting either simultaneous or scan mode in the CHANNEL menu CHANNEL MODE function. Simultaneous mode shows one to four channels in the upper display simultaneously. Scan mode shows one channel at a time (in large digit format) scanning through one to four channels depending on the channels that are enabled. After the mode has been selected, use the CHANNEL menu ENABLE CHANNEL function, to select the channel to be displayed. Any channel set to ‘Off’ is not displayed. See Sections 7.1.3, Channel Mode, and 7.1.2, Enable Channel, for more information.

6.8.3 Selecting Conversion Type and Probe Characterization

Before the 1529 can accurately measure temperature, it must be configured to calculate temperature from the resistance or voltage of the sensor. There are many temperature conversion algorithms available and the one to use depends on the type of sensor and its calibration. Many conversion algorithms use coef ficients that characterize the sensor. Coefficients are determined when the sen sor is calibrated. SPRTs and RTDs often use the ITS-90 algorithms and are provided with ITS-90 characterization coefficients. Thermistors often use the Steinhart-Hart algorithms and coefficients. Thermocouples use standard tables or equations depending on its type. For additional information on conversion types, see Section 7.2, Probe Menu.

The conversion type and characterization coefficients for a sensor are specified using the PROBE menu EDIT PROBE function (see Section 7.2.1).

6.9 Fast Measurement Mode

Fast Measurement Mode applies to measure periods of 0.1, 0.2, or 0.5 seconds. This mode allows measurements to be displayed or logged quickly.

Normally, when each measurement is made a self-calibration of the measure ment circuit is performed simultaneously during the measurement process to offset errors from component drift and spurious EMFs. For measure periods of

0.1, 0.2, and 0.5 seconds, the fast measurement rate is achieved by foregoing

the self-calibration. The drawback to this Fast Measurement Mode is the accu racy of the measurement may be poor and subject to drift. Accuracy can be temporarily improved using the AUTO-CAL function that appears in the CHANNEL menu when in this Fast Measurement Mode. The AUTO-CAL function causes the instrument to perform a single self-calibration of the mea surement circuit then resume fast measuring (without automatic self-calibration).

See Section 8.1.1 for detailed information on using the Fast Measurement Mode.

ITS-90 Conversion

The ITS-90 conversion is for PRTs calibrated and characterized using the Inter national Temperature Scale of 1990 equations. The parameters that appear

when ITS-90 is selected are RTPW, A4, B4, A, B, C, and D. These should be set with the corresponding values that appear on the calibration certificate for the PRT. The parameter RTPW takes the triple point of water resistance from the certificate. The parameters A, B, C, and D take the an,bn, cn,anddcoeffi cients from the certificate, where n is a number from 6 to 11. Parameters A4 and B4 take the a4 and b4 coefficients on the certificate. Any ITS-90 parameter

of the 1529 that does not have a corresponding coefficient on the PRT certifi

cate must be set to 0.

When the ITS-90 conversion type is selected, the RANGE, WIRES, and coeffi cients are displayed on the right portion of the bottom of the display. The UD

buttons are used to scroll through the coefficients. Use the Enter buttontoedit and to save the new settings. Use the LR buttons to change each digit of the

The RANGE parameter is used to select the appropriate resistance range. For 25 ohm and 100 ohm PRTs select 100 ohms and for 1000 ohm PRTs select 10K ohms.

The WIRES parameter sets the appropriate number of lead wires from the sen

sor. This parameter can be set to 2-, 3-, or 4-wires. See Figure 5 on page 22 for the wiring configuration.

The following table shows which parameter to set for each of the coefficients that may appear on the certificate. Note: If the certificate has two sets of coeffi

cients, one set for “zero-power” calibration and one set for 1 mA calibration, use the coefficients for the 1 mA calibration.)

The user-defined parameters for the thermistor T(R) conversion are A0 (A0) through A3 (A port. If A

) as shown on a typical Hart Scientific thermistor calibration re

is not used, as is the case with some calibrations, A2 should be set to

0.0.

Note: Thermistor coefficients stated on the thermistor calibration report may be labeled differently. The best way to identify the coefficients to use with this type is to match the equation above with the equation given on the calibration report. Also, recognize that the coefficients for this equation generally have negative exponents, e.g. A3: 1.39456E-07.

7.2.1.10 Standard Thermocouple Conversions

Note: An Application Note for use of Tungsten-Rhenium and other

thermocouples is available at www.hartscientific.com.

Standard thermocouple conversions include types B, E, J, K, N, R, S, T, and Au-Pt. Voltage is converted to temperature using standard reference functions. (For additional information consult the publication NIST Monograph 175.)

You can specify internal or external reference junction compensation (RJC) with the RJC parameter. (See Table 9 on page 125.) With internal RJC, the tem perature of the thermocouple cold junction is measured automatically and used to calculate the absolute temperature of the thermocouple. With external RJC, a reference junction at a known fixed temperature is used and the value of this fixed temperature reference must be entered in the RJT parameter and is used to calculate the absolute temperature of the thermocouple.

Conversions for each of the thermocouple types accept functional calibration data. This can be used to improve the measurement accuracy. The parameter, Tn, is the temperature of the point in degrees Celsius. The parameter, ADJn, is the temperature deviation from the reference function at the point in degrees Celsius. The temperature measurement is adjusted by this amount when measuring at this temperature. A polynomial interpolation function is used for measurements between calibration points. If calibration data is not available or is not to be used, the ADJn parameters should all be set to 0.0. This causes the temperature to be calculated according to the standard reference functions.

User’s Guide

The user-defined parameters for the thermocouple polynomial conversion are the coefficients c

(C0) through c6(C6). The user can specify internal or exter

nal reference junction compensation (RJC; see Table 9 on page 125). If external RJC is selected, the user enters the temperature of the RJC reference in the ref erence junction temperature (RJT) parameter.

The output of the thermocouple, in millivolts, at 25°C with the reference junc tion at 0°C, is mV (25°C). For example, for a type K thermocouple, mV(25°C) is 1.0002.

7.2.2 Copy Probe

The COPY PROBE function allows you to copy a set of probe parameters from one channel or memory location to another. The parameters are copied from the user selected source channel or memory location into the current channel. The COPY PROBE function can be password protected to restrict access. See Sec tion 7.5.3, Password, for more information. If this function is password pro tected, the user is prompted to enter the password to gain access. If an incorrect password is entered, the display shows the message PASSWORD INCOR RECT and access is denied. If the correct password is entered or if this function is not password protected, the bottom portion of the display appears showing the source channel or memory location, the probe serial number, and the conversion type.

8 Digital Communications Interface

8.1 Overview

The communication feature allows an external device, such as a computer, to communicate with the 1529 to obtain measurement data and control operating conditions. Communication is accomplished by issuing commands to the 1529 through RS-232 or IEEE-488 communication ports.

8.2 Communications

Overview

The thermometer readout is equipped with an RS-232 serial interface, and op tionally a GPIB port. The serial interface allows communications up to dis tances of approximately 50 feet. The serial interface and GPIB port allow the user to access the functions, parameters, and settings discussed in Section 7, Menu Functions.

8.2.1 Serial Wiring

The serial communications cable attaches to the thermometer readout through the DB-9 connector at the back of the instrument. Figure 49 shows the pin-out of this connector and suggested cable wiring. This type of cable is typically referred to as a “null modem” cable. To eliminate noise, the serial cable should be shielded with low resistance be tween the connector (DB9) and the shield.

The serial period, baud rate, linefeed, and echo are programmable. Refer to Section 7.5.1.1, Serial Port, for instructions on accessing and setting these parameters.

All commands sent to the 1529 through the serial in

Figure 49 Serial Cable Wiring

Page 84

1529 Chub-E4 Thermometer Readout

User’s Guide

terface must be terminated with a carriage return or linefeed character.

8.2.2 GPIB Communications

The GPIB interface allows the Model 1529 to be connected to an IEEE-488 bus along with other instruments. A system controller can remotely control the op eration of the Model 1529 and read measurements.

8.2.2.1 Capability

The Model 1529 GPIB interface conforms to standard IEEE-488.2, 1992. Its capabilities are identified as SH1, AH1, T6, L4, SR1, DC1, and E2. The inter face has the capabilities of talk, listen, serial poll, and device clear. There is no capability for talk-only, listen-only, extended talk or listen, parallel poll, re mote-local control, or trigger nor can it act as a controller. The IEEE-488 com mands GET, GTL, LLO, and REN are accepted without error but ignored.

8.2.2.2 Connection

The IEEE-488 port is located on the back of the 1529. Use a standard IEEE-488 cable to connect to your GPIB controller. A shielded cable should be used to prevent EM emission.

8.2.2.3 Device Setup

The Model 1529 system must be set up to respond to the controller address. Refer to Section 7.5.1.2, GPIB, for setting address and other parameters for the IEEE-488 port.

8.3 Interface Commands

8.3.1 Command Summary

An alphabetical listing of the commands implemented by the 1529 are shown in Table 3 starting on page 79. These commands can be used with either serial or IEEE-488 communications ports.

8.3.2 Command Syntax

The 1529 accepts commands that set parameters, execute functions or respond with requested data. These commands are in the form of strings of ASCII-en coded characters. As far as possible, the 1529 conforms to IEEE-488.2, 1992 and SCPI-1994. One notable exception is that compound commands are not al lowed as explained below.

Commands consist of a command header and, if necessary, parameter data. All commands must be terminated with either a carriage return (ASCII 0D hex or 13 decimal) or new line character (ASCII 0A hex or 10 decimal).

Command headers consist of one or more mnemonics separated by colons (:). Mnemonics may use letter characters, the underscore character (_), and possi bly numeric digits as well. Commands are not case sensitive. Mnemonics often have alternate forms. Most mnemonics have a long form that is more readable and a short form consisting of three or four characters that is more efficient.

Page 90

1529 Chub-E4 Thermometer Readout

User’s Guide

A mnemonic may end with a numeric suffix that specifies one of a set of inde pendent function blocks such as input channel data paths. If a numeric suffix is omitted when a particular block must be specified, an error is generated (“Header suffix out of range”).

Query commands are commands that request data in response. Query com mands have a question mark (?) immediately following the command header. Responses to query commands are generated immediately and placed in the output buffer. Responses are then transmitted automatically over the RS-232 port. When using the IEEE-488 interface, responses remain in the output buffer until read or until another command is received or the power is turned off. Re sponses are lost if not read before the next command is received. Each input buffer holds 128 characters and each output buffer holds 256 characters.

Some commands require parameter data to specify values for one or more pa rameters. The command header is separated from the parameter data by a space (ASCII 20 hex or 32 decimal). Multiple parameters are separated by a comma (,).

The 1529 does not allow compound commands (multiple commands per line separated with semicolons). All commands are sequential. The execution of each command is completed before subsequent commands are processed.

8.4 Commands

Table 3, Alphabetical List of Commands in Section 8.3.1, lists the commands in alphabetical order. In this section the commands are arranged into the following groups:

Measurement Commands – commands for reading measurement data.

Measurement Control Commands – commands for the timing and action of

the measurement process.

Channel Commands – commands for selecting channels.

Probe Commands – commands for temperature conversion and probe

characterization.

Calibration Coefficient Commands – commands for channel calibration coefficients.

Display Commands – commands for display options and settings.

Logging Commands – commands for automatic and demand logging.

System Commands – commands for general system configuration parameters.

Communication Interface Commands – commands for controlling the inter

face configuration(serial port and IEEE).

Date and Time Commands – commands for setting the date, time and the date and time formats.

Page 91

8 Digital Communications Interface

Commands

Password Commands – commands for enabling and disabling the password, for setting the password, and for checking the state of the password.

Status Commands – commands to report the status and condition of the instrument.

Each section provides the command structure (long and short format), a de

scription of the command purpose, a command example, an example of what the command returns (as applicable to query commands), and notes specific to the command. The following apply to each group of commands.

Numeric data, specified by the mnemonic, <num>, uses ASCII characters

•

to represent numbers. Numbers may contain a plus or minus (‘+’ or ‘-’) sign, decimal point (‘.’), and exponent (‘E’ or ‘e’) with its sign. If a frac

tional component is received when only an integer is required, the number is rounded to the nearest integer without any resulting error message. The mnemonics DEF, MIN, and MAX are often acceptable for the default, minimum, and maximum value respectively. Unit suffixes, such as V or OHM, can be appended to numeric parameters and are accepted without error but ignored.

• Unrecognized commands or commands with incorrect syntax or invalid

parameters generate error messages in the error queue.

• Upper case letters designate syntax that is required when issuing the com-

mand. Lower case letters are optional and may be omitted.

• <> indicates a required parameter.

• [] indicates optional parameters.

• () indicates a group of parameters that must be used together.

• For query commands, specifying the MIN, MAX, or DEF parameter

causes the instrument to respond with the minimum, maximum, or default setting respectively.

•

For set commands, specifying the MIN, MAX, or DEF parameters causes the instrument to use the minimum, maximum, or default setting respec

tively.

•

‘|’ indicates alternate parameter values.

•

<chn> indicates a channel number is required.

•

<dest chn> indicates a destination channel is required.

•

<n> indicates a number is required.

CALC:AVER:CLE

The *RST command clears the statistical functions.

8.4.1.2 CALCulate<chn>:AVERage<n>:DATA?

Returns the value of a statistical calculation for a given channel.

CALC3:AVER1:DATA?

0.017

The CALCulate suffix, <chn>, specifies the channel (1 to 4). The AVERage suffix, <n>, specifies the calculation type. See Table 4 on page 122 for the Sta tistical Calculation Types.

8.4.1.3 CALCulate:AVERage<n>:TYPE?

Returns the keyword for the specified field type number.

CALC:AVER2:TYPE

STD

Page 93

The AVERage suffix, <n>, specifies the calculation type number. See Table 4 on page 122 for the Statistical Calculation Types.

8.4.1.4 FETCh? [<chn>]

Returns the most recent measurement for the specified channel.

FETC? 1

0.0000011

1,2,0.0011,mV,14,5,35,2000,9,5

The <chn> parameter specifies the channel (1 to 4). If the <chn> parameter is omitted, the most recent measurement is returned regardless of the channel. If simultaneous sampling is on, the measurement from the lowest enabled channel number is returned. This command does not affect the measurement action.

If the extended format setting is OFF (see Section 9.4.1.5, FORMat:STAMp <bool>) the response is only the measurement value in units of temperature, volts, or ohms depending on the selected probe type or temperature unit. With this format kohms and millivolts are converted to ohms and volts respectively.

If the extended format setting is ON the measurement is returned in a comma-delimited format as follows.

Measure status (0 if the measurement has been read previously or 1 if this is a new measurement,

channel number,

measurement value,

scale,

hour,

minute,

seconds,

year,

month,

day the measurement was made

With this format kohms and millivolts are not converted to ohms and volts.

This command may return the same reading if a new reading has not yet been obtained. If only new readings are desired, the FORMat:STAMp command can be used to enable the extended format option and any readings in which the value of the first field is 0 can be ignored or else the STATus:MEASure? com mand can be used to determine if a new reading is available for a desired channel.
