described in Specifications section. The calibrator also has a Cold Junction Compensation (CJC) function. Normally this function should be ON and the actual temperature of the thermocouple will be measured. With CJC OFF, the calibrator will measure the difference between the thermocouple at the junction and at its TC input terminal. Note: CJC off mode should only be used when calibration is being done using an external ice bath. To use the thermocouple to measure temperature, follow these steps: 1.
The calibrator accepts two, three, and four wire inputs, with four wire input being the most accurate. To use the RTD option, apply the following steps: 1. Switch to lower display [LOWER] from Main Menu. 2. Select RTD from the primary parameters. Select [IN] from input/output control. 3. Choose 2, 3, or 4-wire connection [2W, 3W, 4W]. (4-wire allows for the most precise measurement) 4. Select RTD type from the sensor types. 5. Attach RTD leads as shown in Figure 8. Figure 8.
Caution To avoid mechanically damaging the pressure module, never apply more than 10 ft-lb. of torque between the pressure module fittings, or between the fittings an the body of the module. To avoid damaging the pressure module from overpressure, never apply pressure above the rated maximum printed on the module. To avoid damaging the pressure module from corrosion, use it only with specified materials. Refer to the pressure module documentation for material compatibility.
To adjust the calibrator, follow these steps: 1. Enter the pressure zeroing menu. 2. Select [ZERO ]. [SET REFERENCE ABOVE] will appear. Enter the pressure using the keypad. 3. The calibrator stores the Barometric zero offset in nonvolatile memory. The zero offset is stored for one absolute pressure module at a time. If a new absolute module is connected this process must be repeated. 4.
4.1-1 Stepping the current output To use the 25% function with mA output, follow these steps: 1. Select the lower display from the Main Menu, and choose mA. 2. Use the 25% key to cycle between 4 mA and 20 mA in 25 % intervals. 4.2 Using the Automatic Output Functions There are two automatic output functions, step and ramp. The selected function can be turned on and off using the Output Home Menu. The Automatic Output Function parameters can be set in the Auto Function Menu. Parameters include: 1.
4.3-1 HART™ Resistor Selection The DMC1400 can be set-up so that the 250 ohm resistor required for HART™ configuration devices resides inside the DMC1400. Enabling the DMC1400's internal 250 ohm resistor eliminates the need to manually add a series resistor during a HART™ calibration process. NOTE: When the DMC1400's internal 250 resistor is enabled, maximum load driving capability drops from 1000 ohms @ 20mA to 750 ohms @20mA. Enable/Disable Procedure 1.
2. Choose mA simulation from the primary parameters [mA 2W SIM], and enter the desired current. 3. Connect the 24V loop as shown in Figure 11. Figure 11.

Figure 22. Calibrating a Pressure Transmitter 7. Remote Operation The calibrator can be remotely controlled using a PC terminal, or by a computer program running the calibrator in an automated system. It uses an RS-232 serial port connection for remote operation. With this connection the user can write programs on the PC, with Windows languages like Visual Basic to operate the calibrator, or use a Windows terminal, such as Hyper Terminal, to enter single commands.
7.1 Setting up the RS-232 Port for Remote Control Note: The RS-232 connection cable should not exceed 15m unless the load capacitance measured at connection points is less than 2500pF. Serial parameter values: 9600 baud 8 data bits 1 stop bit no parity Xon/Xoff EOL (End of Line) character or CR (Carriage Return) or both To set up remote operation of the calibrator on the Windows Hyper Terminal, connected to a COM port on the PC as in Figure 23, use the following procedure: 1.
2. To enable Remote with Lockout, type in REMOTE and LOCKOUT in either order. 3. To switch back to local operation enter LOCAL at the terminal. This command also turns off LOCKOUT if it was on. For more information on commands refer to the Remote Commands section. 7.3 Using Commands 7.3-1 Command types Refer to the Section on Remote Commands for all available commands. The calibrator may be controlled using commands and queries. All commands may be entered using upper or lower case.
Overlapped Commands Commands that require more time to execute than normal. The command *WAI can be used after the overlapped command to tell the calibrator to wait until the command finishes before executing the next command. For example: TRIG; *WAI Triggers the pulse train. Once the pulse train has been triggered, the calibrator can proceed to the next command. Sequential Commands Commands that are executed immediately after the are entered. This type includes most of the commands. 7.
Indefinite ASCII (IAD) Any ASCII characters followed by a terminator. For example: *IDN? returns MARTEL, ASC300, 250, 1.00 7.3-4 Calibrator Status Status registers, enable registers, and queues provide status information on the calibrator. Each status register and queue has a summary bit in the Serial Poll Status Byte. Enable registers generate summary bits in the Serial Poll Status Byte. The following is a list of registers and queues along with their function.
Event Status Enable Register (ESE) Enables and disables bits in the ESR. Setting a bit to 1 enables the corresponding bit in the ESR, and setting it to 0 disables the corresponding bit. Cleared at power reset. Bit assignments for the ESR and the ESE respectively are shown below. 15 14 13 12 11 10 9 8 0 0 0 0 0 0 0 0 7 6 5 4 3 2 1 0 PON 0 CME EXE DDE QYE 0 OPC PON Power On. Set to 1 if power was turned on and off before the Event Status Register was read. CME Command Error.
Error Queue If an error occurs due to invalid input or buffer overflow, its error code is sent to the error queue. The error code can be read from the queue with the command FAULT?. The error queue holds 15 error codes. When it is empty, FAULT? returns 0. The error queue is cleared when power is reset or when the clear command *CLS is entered. Input Buffer Calibrator stores all received data in the input buffer. The buffer holds 250 characters. The characters are processed on a first in, first out basis.

parameters that may be entered with the command as well as what the output of the command is. 7.5-1 Common Commands *CLS Clears the ESR, the error queue and the RQS bit. Also terminates all pending operations. When writing programs, use before each procedure to avoid buffer overflow. *ESE Loads a byte into the Event Status Enable register. The command is entered with a decimal number that, when converted to binary, enables the right bits in the Event Status Register.
*OPC? Returns 1 when all operations are complete, and causes program execution to pause until all the operations are complete. For example: TRIG ; *OPC? will return a 1 when the pulse train initiated by TRIG is complete. *RST Resets the state of calibrator to the power-up state. All subsequent commands are held off until the execution of the command is complete. *SRE Loads a byte into the Service Request Enable register.
7.5-2 Calibrator Commands CAL_START Puts the calibrator in calibration mode. The main display will say CALIBRATION MODE and a calibration menu will be displayed on the terminal. CJC_STATE Turns Cold Junction Compensation (CJC) on or off, when the calibrator is in thermocouple (TC) mode. The command is used by adding ON or OFF after it. For example: CJC_ STATE OFF turns CJC off. CJC_STATE? Tells whether the Cold Junction Compensation in thermocouple mode is turned on or turned off.
CPRT_COEFB? Returns the number, which was entered for the first coefficient of the polynomial used in the custom RTD. Using the example above, CPRT_COEFB? Would return: -5.801900E-07 CPRT_COEFC This command is used for entering a custom RTD into the calibrator. The numeric value entered after the command will be set as the first coefficient of the polynomial used by the custom RTD. For example: CPRT_COEFC -5.8019E-12 enters -5.8019e-12 as coefficient A.
CPRT_MIN_T? Returns the value entered for minimum temperature in the range for a custom RTD. The above example would return: 0.000000E+00, CEL CPRT_R0 Sets the 0° resistance, R0, in the custom RTD. The value must be entered with a units label. Refer to the Parameter Units table for assistance. For example: CPRT_R0 100 OHM sets R0 to 100 ohms. CPRT_R0? Returns the value for the resistance in custom RTD. The above example would return: 1.
FREQ_TYPE When in frequency mode, sets the calibrator to output a continuous wave (Frequency Out), or a pulse train. To set the calibrator to continuous wave enter CONT after the command. To set the calibrator to pulse enter PULSE after the command. For example: FREQ_TYPE CONT will set the calibrator to FREQ OUT. Note: This command does not put the calibrator in frequency mode. Use the OUT command to put the calibrator in frequency mode.
LOCAL Restores the calibrator to local operation if it was in remote mode. Also clears LOCKOUT if the unit was in lockout mode. LOWER_MEAS Sets the lower display to measure mode. The command is followed by any of the parameters except for pulse and mA sim, which are source only. Enter DCI for mA, DCV for volts, TC for thermocouple, RTD for RTD, FREQUENCY for frequency, and PRESSURE for pressure.
PRES_UNIT? Returns the pressure units of both the upper and the lower display. For example if the unit on the upper display is bars, and on the lower it is psi, the command will return: BAR, PSI PULSE_CNT Sets the number of pulses the calibrator will produce when it is triggered while in pulse mode. For example; PULSE_CNT 3000 will set the number of pulses to 3000. PULSE_CNT? Returns the number of pulses in the pulse train.
wire. For example: RTD_WIRE 4W sets the connection to 4-wire RTD_WIRE? Returns the number of wires used in the RTD connection. SET_CLOCK yyyy mm dd hh nn ss Sets the calibrator date and time, where yyyy is the four digit year (2006 to 2100), mm is the two digit month (1 to 12), dd is the two digit day (1 to the number of days in the specified month), hh is the two digit hour in 24 hour format (0 to 23), nn is the two digit minute (0 to 59), and ss is the two digit second (0 to 59).

TAG_UPLD See the separate Tag Download and Upload Procedures manual for detailed instructions on using this command to upload tag calibration test results to a PC from the calibrator. TAGS? Sends a list of all tag ID's in the calibrator to a PC.
TRIG Starts and stops the pulse train when the calibrator is in pulse mode. The parameters of the pulse train are set by commands PULSE_CNT, and FREQ_LEVEL. Entering TRIG initializes the train. Entering the command while the pulse train is running stops it. TRIG? Returns TRIGGERED if the pulse train is running, and returns UNTRIGGERED when the pulse train is not running. Returns NONE when the calibrator is not in pulse mode.
ZERO_MEAS Zeroes the attached pressure module. Enter the zeroing value in PSI after the command when zeroing an absolute pressure module. ZERO_MEAS? Returns the zero offset or the reference value for absolute pressure modules.
8. Document Mode 8.1 Introduction Document mode allows an instrumentation technician to create repeatable calibration tests for up to 50 tags while in the field, to download predefined calibration tests from a PC database for up to 50 tags before going to the field, or some combination of both types up to a maximum of 50 tags. Each test may consist of 1 to 21 user selectable test points, and may be repeated as many times as necessary to complete adjustment and calibration of the tag.
Once the last point has been tested, the As Found test automatically ends, the real time clock time stamp is saved, and the technician is prompted for changes to the tag identification data (any field but tag number which can not be changed). If test validation was selected, the technician has the option of displaying the As Found test results.
