This command is the CALIBRATION QUERY. The analog to digital (A/D) converters
within the 6810B require periodic calibration to maintain specified accuracy. This
calibration is performed automatically by the internal microprocessor once every ten
minutes. The calibration query can be sent to execute the calibration independent of the
routine ten minute cycle.
When.sent, the 6810B performs the A/D calibration. The query responds with a message
indicating that calibration has been completed successfully.
*
:
0 - Successful calibration
1 - Problem encountered during calibration
Sending the CLEAR STATUS command resets the Standard Event Register (*ESR?),
Status Byte (*STB?) and Error Queue (ERR?) to zero. This command may be used to
clear the status registers before enabling SRQ generation from instrument events.
