12.6 Entering Commands
Commands for the calibrator may be entered in upper or lower case. There is at least
one space required between the command and parameter, all other spaces are optional.
Almost all commands for the calibrator are sequential; any overlapped commands will be
indicated as such. This section will briefly explain each of the commands and describe
their general use, which will include any parameters that may be entered with the
command as well as what the output of the command is.
12.6.1 Common Commands
*CLS
Clears the error queue. Also terminates all pending operations. When writing programs,
use before each procedure to avoid buffer overflow.
*IDN?
Returns the manufacturer, model number, and firmware revision of the Calibrator. For
example:
*IDN? will return BETA, 311A/321A, 0, 1.00
12.6.2 Calibrator Commands
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 3.908300E-03 enters 3.908300e-3 as coefficient A.
CPRT_COEFA?
Returns the number that was entered for the first coefficient of the polynomial used in
the custom RTD. Using the example above CPRT_COEFA? Would return:
3.908300E-03
