5.5-2 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. The calibrator returns OFF if CJC is off, and ON if CJC is on.
CPRT_COEFA
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_COEFA 3.908E-03 enters 3.908e-3 as coefficient A.
CPRT_COEFA?
Returns the number which was entered for the first coefficient of the polynomial used in the
custom RTD. Using the example above CPRT_COEFA? Would return:
3.908000E-03
CPRT_COEFB
This command is used for entering a custom RTD into the calibrator. The numeric value
entered after the command will be set as the second coefficient of the polynomial used by the
custom RTD.
For example:
CPRT_COEFB -5.8019E-07 enters -5.8019e-7 as coefficient B.
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
