Calibration Commands
Refer to “Calibration” on page 82 for an overview of the calibration features of the
power supply. An example program for calibration is listed in “Calibration
example” on page 123. For more detailed information on the calibration
procedures, refer to the Chapter 8, "Service and Maintenance".
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 5 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.
CALibration:CURRent:LEVel {MINimum|MIDdle|MAXimum}
This command can only be used after calibration is unsecured and the output
state is ON. It sets the power supply to a calibration point that is entered with
CAL:CURR command. During calibration, three points must be entered and the
low-end point (MIN) must be selected and entered first.
When you calibrate the power supply, you should not set the OVP to ON state in
order to prevent OVP from tripping.
