The ERR? and AUXERR? commands return the decimal sum of all set bits in the
error register and the auxiliary error register, respectively. Refer to these
commands in
Calibration
The multimeter has two forms of calibration: external calibration and
autocalibration. The external calibration involves a procedure using external
reference sources. Refer to the 3458A Calibration Manual for more information on
the external calibration.
The CALNUM? query command returns a number indicating the number of times
the multimeter has been externally calibrated. By routinely checking this number,
you can monitor the calibrations performed on the multimeter. The following
program reads and returns the present calibration number.
10 OUTPUT 722;"CALNUM?"
20 ENTER 722;A
30 PRINT A
