Cautiously handle probes to prevent personal injury. Carefully place probes on a heat/cold resistant surface or rack until they reach room temperature.

●

If this equipment is used in a manner not specied by the manufacturer, the protection provided by the equipment may be impaired.

●

Before initial use, or after transport, or after storage in humid or semi-humid environments, or anytime the instrument has not been energized for more than 10 days, the instrument needs to be energized for a “dry-out” period of 2 hours before it can be assumed to meet all of the safety requirements of the IEC 1010-1. If the product is wet or has been in a wet environment, take necessary measures to remove moisture prior to applying power such as storage in a low humidity temperature chamber operating at 50 °C for 4 hours or more.

●

The AC adapter can present safety concerns if misused or damaged. To avoid the risk of electric shock or re, do not use the AC adapter outdoors or in a dusty, dirty, or wet environment. If the cord, case, or plug of the adapter is damaged in any way, discontinue its use immediately and have it replaced. Never disassemble the AC adapter. Use only the AC adapter provided with the instrument or equivalent adapter recommended by the manufacturer of this instrument.

supply, and have it replaced. Do not attempt to open, repair, or continue using a damaged or defective AC adapter.

●

The instrument batteries can present danger if not handled properly. To avoid the risk of exposure to dangerous substances or explosion, immediately remove the batteries and discontinue use if they leak or become damaged. Never allow the batteries to be shorted, heated, punctured, or dropped. If the instrument is physically damaged, immediately remove the batteries to insure that they do not become shorted. While removed from the instrument, store the batteries in a location so that they do not come into contact with metal or uids that might short circuit the batteries and where they are safe from excessive temperatures. Used batteries must be disposed of properly. Check your local regulations for additional information. Never dispose of batteries in re which may result in explosion with the possibility of personal injury or property damage.

●

DO NOT use this instrument in combination with any probe ( PRT, thermistor, or thermocouple) to measure the temperature or resistance of any device where the probe might come in contact with a conductor that is electrically energized. Severe electric shock, personal injury, or death may occur.

1.2.2 Cautions

●

If the instrument is dropped, struck, or handled in a way that causes internal or external physical damage, immediately unplug the AC adapter, remove the batteries, discontinue use, and contact the factory for repair.

The sensor generally limits the actual temperature range. Temperature accuracy speciﬁcations do not

include sensor accuracy. Thermistor temperature accuracy assumes a 10kW sensor. Thermocouple accuracy is with internal reference junction compensation; accuracy is improved with external reference junction compensation. Thermocouple temperature accuracies are given for external reference junction compensation and internal reference junction compensation, respectively.

Measurement accuracy speciﬁcations apply within the operating temperature range and assume 4-sample

averaging and 4 lead wires for PRTs. With 3-wire RTDs add 0.05W to the measurement accuracy plus the maximum possible difference between the resistances of the lead wires.

Actual resolution can be set greater than typical resolution, but the added digits (0.0001 max.) may not be

meaningful to the measurement.

3.2 Use Proper Care

You must understand the safety issues related to the 1529. Be aware that potential hazards exist due to high temperatures and battery chemicals. Carefully read the Warnings and Cautions in Section 1.2, Safety Information on page 3.

The 1529 and any thermometer probes used with it are sensitive instruments that can be easily damaged. Always handle these devices with care. DO NOT allow them to be dropped, struck, stressed, or over-heated.

3.3 Learn About the Features and Components

Familiarize yourself with the features and accessories of the 1529 by reading Section 4, Parts and Controls on page 13.

3.4 Connect the Probe

The PRT/thermistor or thermocouple probe connects on the back panel of the 1529 using patented mini-DWF connectors (PRT/thermistor) or the universal receptacles (thermocouples).

3.4.1 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

Page 20

1529 Chub-E4 Thermometer Readout

Connect the Power Source

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, especially if it the product is used near sources of EM interference such as heavy industrial 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 on this page The ferrite can be easily snapped open and moved to a new probe when needed.

3.5 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 14).

3.6 Switch the Power On

Power is turned on and off with the power switch located on the top right corner 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’ position. The instrument takes a few seconds to power up, initialize, and begin normal operation. A self-test is performed displaying the channel conguration and status of the system, calibration, GPIB, memory, and buttons. If the thermometer readout calibration has expired, the user is notied and must press the Enter button to continue initialization. If an error message is displayed on power up see Section 10, Troubleshooting on page 125.

3.7 Measure Temperature

After initialization, the temperature measurements for the congured channels are displayed. The appropriate sensor type must be selected and coefcients entered for the measurements to be accurate (see Section 6.2.1, Edit Probe on page 30). 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 dam-

General Operation

5 General Operation

This section explains basic operation of the 1529 thermometer readout. Detailed operation of the 1529 is explained in Sections and . Section explains the menu structure and the functions available in the menu structure and Section explains the communications interface for operating the 1529 remotely.

5.1 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 elds and eld display sets. Information 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 programmable elds and eld display set information are not displayed.

5.2 Changing Units

The 1529 thermometer readout is capable of displaying temperature in Celsius (C), Fahrenheit (F), or Kelvin (K). (Displaying in units of W, KW, or mV is also available through the PROBE menu and is channel specic.) 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 elds that are displaying temperature on the upper or lower display are updated to the new units.

Channels that are set to W, KW, or mV in the PROBE menu are left unchanged when temperature units are modied. Changing the units resets the statistical calculations (displayed in the bottom portion of the display).

Battery

5.3 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 recharged. The battery discharges more quickly when the display backlight is used. The percent of battery charge remaining is displayed on the bottom portion of the display when the battery power is being used. The battery percentage 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 instrument is switched on. The power control circuit inside the instrument manages battery charging and stops charging the battery automatically when the battery 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

Page 28

1529 Chub-E4 Thermometer Readout

Probe Input Modules

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 temperature is warm. The battery pack can be used for a minimum of 500 charge-discharge 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 eld 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 battery 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 re 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 affected. If the power is interrupted while the instrument is logging measurements (on demand or automatically), the logged data is preserved and logging resumes when the power is restored.

5.4 Probe Input Modules

The 1529 can be congured 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 congured at the factory and is not eld changeable. Input modules should never be removed for any reason.

All possible congurations are shown in Figure 3 on page 14.

5.4.1 Connecting a PRT or Thermistor Probe

PRT and thermistor probes are attached to the resistance input module via Hart Scientic 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.

Page 29

When using 2- and 3-wire sensors, the accuracy of the 1529 is reduced as stated in

Channel 1 Channel 2

the specications. Compensation is made for 3-wire PRTs, but the difference in lead resistance affects the measurement accuracy. The 1529 thermometer readout is unable to compensate for 2-wire lead resistance.

Attach the lead-wires of the probes as shown in Figure 4 on this page. The top termainals sense current and the bottom terminals sense potential.

5.4.2 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.

Figure 5 Thermocouple Connections

5.5 DC Power Source

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

shipped with the instrument by Hart Scientic. If the AC adapter needs to be replaced, contact an Authorized Service Center (see Section 1.3, Authorized Service Centers on page 4).

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 re if exposed. If the AC adapter is damaged in any way or becomes hot, discontinue use immediately, disconnect the adapter from any AC supply, and replace the adapter. Do not attempt to open, repair, or continue using a damaged or defective AC adapter.

Page 31

5.6 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 10.1, Troubleshooting on page 125 for additional information on error messages.

5.7 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 OPTIONS function. If the display appears faded, dark, or blank, adjust the contrast (off, low, medium, high) using the front panel contrast buttons.

5.8 Taking Measurements

The procedure for conguring the 1529 thermometer readout to take measurements on a particular input channel requires the following: (1) connecting the sensor to the appropriate input channel , (2) enabling the channel, and (3) selecting the conversion type and probe characterization values.

5.8.1 Connecting the Sensor

Connect the sensor to the RTD/Thermistor channel(s) or thermocouple channel(s) that you want to measure. Refer to Section 5.4, Probe Input Modules on page 18, for additional information.

General Operation

Taking Measurements

5.8.2 Enabling the Channel

Channels are set rst 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 Section 6.1.3, Channel Mode on page 26, and Section 6.1.2, Enable Channel on page 26, for more information.

5.8.3 Selecting Conversion Type and Probe Characterization

Before the 1529 can accurately measure temperature, it must be congured 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cients that characterize the sensor. Coefcients are determined when the sensor is calibrated. SPRTs and RTDs often use the ITS-90 algorithms and are provided with ITS-90 characterization coefcients. Thermistors often use the Steinhart-Hart algorithms and coefcients. Thermocouples use standard tables or equations depending on its type. For additional information on conversion types, see Section 6.2, Probe Menu on page 29.

Page 32

1529 Chub-E4 Thermometer Readout

Fast Measurement Mode

The conversion type and characterization coefcients for a sensor are specied using the PROBE menu EDIT PROBE function (see Section 6.2.1, Edit Probe on page 30).

5.9 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 measurement 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 accuracy 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 measurement circuit then resume fast measuring (without automatic self-calibration).

See Section 6.1.1, Measure Period and Fast Measurement Mode on page 24 for detailed information on using the Fast Measurement Mode.

5.10 Data Logging

Data can be logged either on demand or automatically at a user-selected interval. When data is logged, readings are stored to the instrument’s memory and assigned a label for easy recall and organization of data. Up to 100-demand log and 8,160 auto log readings can be stored. When data is being logged, the left bottom corner of the main display shows a strip-recorder indicator.

6.2.1.1 ITS-90 Conversion

The ITS-90 conversion is for PRTs calibrated and characterized using the Internation- al 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 certicate for the PRT. The parameter RTPW takes the triple point of water resistance from the certicate. The parameters A, B, C, and D take the an, bn, cn, and d coefcients from the certicate, where n is a number from 6 to 11. Parameters A4 and B4 take the a4 and b4 coefcients on the certicate.

Any ITS-90 parameter of the 1529 that does not have a corresponding coefcient on the PRT certicate must be set to 0.

When the ITS-90 conversion type is selected, the RANGE, WIRES, and coefcients are displayed on the right portion of the bottom of the display. The UD buttons are used to scroll through the coefcients. Use the Enter button to edit and to save the new settings. Use the LR buttons to change each digit of the settings. Press and hold the Exit button to cancel to the main display or press the EXIT button to cancel and to move to the next parameter. On the last parameter, press the Exit button to exit the menu.

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 sensor. This parameter can be set to 2-, 3-, or 4-wires. See Figure on page for the wiring conguration.

The following table shows which parameter to set for each of the coefcients that may appear on the certicate. Note: If the certicate has two sets of coefcients, one set for “zero-power” calibration and one set for 1 mA calibration, use the coefcients for the 1 mA calibration.)

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

6.2.1.10 Standard Thermocouple Conversions

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

ples is available at www.hartscientic.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 on page .) With internal RJC, the temperature 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 xed temperature is used and the value of this xed 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.

6.2.1.11 Thermocouple Polynomial Conversion

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

ples is available at www.hartscientic.com.

The thermocouple polynomial conversion allows calculation of temperature by polynomial conversion.

When the Thermocouple Polynomial conversion type is selected, the coefcients are displayed on the right portion of the bottom of the display. Use the UD buttons to scroll through the coefcients. Use the Enter button to edit and save the new setting. Press and hold the Exit button to cancel to the main display or press the EXIT button to cancel and to move to the next parameter. On the last parameter, press the Exit button to exit to the menu.

The following equation is used for the thermocouple polynomial conversion:

The user-dened parameters for the thermocouple polynomial conversion are the coefcients c0 (C0) through c6 (C6). The user can specify internal or external reference junction compensation (RJC; see Table on page ). If external RJC is selected, the user enters the temperature of the RJC reference in the reference junction temperature (RJT) parameter.

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

6.5.1 Comm Setup

The COMM SETUP function (Figure 43 on this page) is used to setup the communication parameters for the installed ports. Communications ports are used for communicating with a computer, printer, or other equipment. When this function is selected, the bottom portion of the display prompts the user to select the communication port to setup. The 1529 thermometer readout is shipped standard with one serial (RS-232) port. A GPIB port may optionally be installed. The GPIB port selection only appears if it is installed. ERRORS may also be selected for the port. This port selection allows the user to view any error messages stored in the error queue on the display. Once an error has been viewed, it is removed from the error queue.

Figure 43

Press the LR buttons to select the port to setup. Press the Enter button to display the port parameters.

6.5.1.1 Serial

When the SERIAL option is selected, the parameters for the serial port are displayed on the bottom portion of the display. These parameters are: BAUD, SER PER, LF, PRINT, and ECHO.

The BAUD parameter allows the user to select the baud rate for communications on this port. The user may choose between 1200, 2400, 4800, 9600, and 19200. The default baud rate is 9600.

The SER PER parameter allows the user to select the interval at which measurements are transmitted over the serial port. The user may choose between 0.1, 0.2, 0.5, 1, 2, 5, 10, and 30 seconds, 1, 2, 5, 10, and 30 minutes, and 1 hour.

The LF parameter allows the user to specify whether a linefeed character (ASCII 0A hex or 10 decimal) is appended to the end of each line transmitted over the serial port. Selecting ON sends both a carriage return (ASCII 00 hex or 13 decimal) and a linefeed. Selecting OFF sends only a carriage return.

The PRINT parameter allows the user to enable printing measurements over the serial port. Selecting ON enables printing and selecting OFF disables printing. With slower MEA PER (see Section ) and SER PER rates of 1 second or more, measurements are printed with the channel number, measured value, unit, time, and date, all separated with spaces. With faster rates, less than 1 second, only the measured value is printed.

The ECHO parameter allows the user to set the echo (duplex) mode. Selecting ON enables echoing so that all characters received on the serial port are echoed back over the serial port. This mode is useful when using terminal emulation software on a computer to communicate with the instrument. Selecting OFF disables echoing. This mode is commonly used when using control software on the computer.

Press the LR buttons to select the parameter setting. Use the UD buttons to scroll between the parameters. Press the Enter button to save the new setting. Press and hold the Exit button to cancel to the main display or press the EXIT button to cancel and to move to the next parameter.

7 Digital Communications Interface

7.1 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.

7.2 Communications

The thermometer readout is equipped with an RS-232 serial interface, and optionally a GPIB port. The serial interface allows communications up to distances of approximately 50 feet. The serial interface and GPIB port allow the user to access the functions, parameters, and settings discussed in Section 6, Menu Functions on page 23.

7.2.1 Serial Wiring

The serial communications cable attaches to the thermometer readout through the DB-9 connector at the back of the instrument. Figure 48 on next page 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 between the connector (DB9) and the shield.

Digital Communications Interface

1529 Chub-E4 Thermometer Readout

Communications

Figure 48 Serial Cable Wiring

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

All commands sent to the 1529 through the serial interface must be terminated with a carriage return or linefeed character.

7.2.2 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 operation of the Model 1529 and read measurements.

7.2.2.1 Capability

The Model 1529 GPIB interface conforms to standard IEEE-488.2, 1992. Its capabilities are identied as SH1, AH1, T6, L4, SR1, DC1, and E2. The interface has the capabilities of talk, listen, serial poll, and device clear. There is no capability for talk-

Page 79

only, listen-only, extended talk or listen, parallel poll, remote-local control, or trigger nor can it act as a controller. The IEEE-488 commands GET, GTL, LLO, and REN are accepted without error but ignored.

7.2.2.2 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.

7.2.2.3 Device Setup

The Model 1529 system must be set up to respond to the controller address. Refer to Section 6.5.1.2, GPIB (Optional) on page 61, for setting address and other parameters for the IEEE-488 port.

7.3 Interface Commands

7.3.1 Command Summary

An alphabetical listing of the commands implemented by the 1529 are shown in Table 7 on this page. These commands can be used with either serial or IEEE-488 communications ports.

7.3.2 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-encoded 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 allowed 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 possibly 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 efcient.

A mnemonic may end with a numeric sufx that species one of a set of independent function blocks such as input channel data paths. If a numeric sufx is omitted when a particular block must be specied, an error is generated (“Header sufx out of range”).

Query commands are commands that request data in response. Query commands 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. Responses 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 parameters. 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.

7.4 Commands

Table 7 on page 69, Alphabetical List of Commands, 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 Coefcient Commands – commands for channel calibration coefcients.

Display Commands – commands for display options and settings.

Logging Commands – commands for automatic and demand logging.

System Commands – commands for general system conguration parameters.

Communication Interface Commands – commands for controlling the interface

conguration(serial port and IEEE).

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

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

●

Numeric data, specied 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 fractional 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 sufxes, 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 command. 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 PRT/Thermistor channels, specifying the MIN parameter returns a value of -9 when the offset sufx <n> is 1 (for PRTs) and -9000 when the offset sufx <n> is 2 (for Thermistors). For Thermocouple channels, specifying the MIN parameter returns a value of -9. For PRT/Thermistor channels, specifying the MAX parameter returns a value of 9 when the offset sufx <n> is 1 (for PRTs) and 9000 when the offset sufx <n> is 2 (for Thermistors). For Thermocouple channels, specifying the MAX parameter returns a value of 9. Specifying the DEF parameter returns a value of 0.
