3.5.3 Remote Calibration
Calibration can be controlled by remote commands. The procedure and prompts are
similar to those used for local calibration. Proceed as follows:
SYSTem LOCKout ON Place unit in local lockout
*SRE 16 Enable the MAV STB bit (IEEE-488 only)
CAL FULL or GCONly Select desired cal type
CAL DATE mmddyy or yyyy Enter the cal date
The calibration will proceed automatically, with the sequence interrupted by requests for
user input. When using the RS-232 interface, the prompt is sent without any action by
the user, with IEEE-488 the unit sets SRQ to request permission to send the prompt (In
multidrop environments, poll SRQ for the configured bus address until the MAV bit is
set, then send a query to retrieve the prompt).
FETCh? When SRQ line asserted (IEEE-488 only)
Read the prompt (returned automatically for RS-232). If the prompt requests a numerical
value, the min and max acceptable value will be displayed. Make the requested
connections and report the value in the form:
CAL f Where f is a floating point number
If the prompt requests the user to “Press Start to Continue” the remote start is issued by
the command:
CAL MEASure Loops back for next FETCh command
The STOP command will work at any time to abort calibration. The final prompt will
read CAL COMPLETE or CAL FAILED.
