Calibration Commands

Calibration Commands
Refer to “Calibration” on page 63 for an overview of the
calibration features of the power supply. For more detailed
discussion on the calibration procedures, refer to the Service
Guide.
CALibration:COUNt?
This command queries the power supply to determine the
number of times it has been calibrated. Your power supply
was calibrated before it left the factory. When you receive
your power supply, read the count to determine its initial
value. Since the value increments by one for each calibration
point, a complete calibration will increase the value by five
counts.
CALibration:CURRent[:DATA] <numeric value>
This command can only be used after calibration is
unsecured and the output state is ON. It enters a current
value that you obtained by reading an external meter. You
must first select the minimum calibration level
(CAL:CURR:LEV MIN) for the value being entered. You must
then select the middle and maximum calibration levels
(CAL:CURR:LEV MID and CAL:CURR:LEV MAX) for the value
being entered. Three successive values must be selected and
entered. The power supply then computes new calibration
constants. These constants are then stored in non- volatile
memory.
NOTE
When you calibrate the power supply, you should not set the OVP to the
ON state in order to prevent OVP from tripping.
