Calibration Commands
Refer to “Calibration” on page 61 for an overview of the
calibration features of the power supply. An example
program for calibration is listed in
“Calibration example” on
page 104. For more detailed discussion on the calibration
procedures, refer to the “Service and Maintenance” on
page 177.
CALibration:COUNt?
Query 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 six 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, 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.
When you calibrate the power supply, you should not set the OVP to the
ON state in order to prevent OVP from tripping.
