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. 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.
