Calibration Commands

See chapter 3 "Calibration Overview", starting on page 60 for an overview of the
calibration features of the power supply. For more detailed discussion of the
calibration procedures, see 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 for three outputs
will increase the value by six counts.
CALibration:CURRent[:DATA]
<numeric value>
This command can only be used after calibration is unsecured. It enters a current
value of a selected output that you obtained by reading an external meter. You must

first select a calibration level (CAL:CURR:LEV) for the value being entered. Two
successive values (one for each end of the calibration range) 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 | MAXimum}
Before using this command, you must select the output which is to be calibrated by
using INSTrument command. This command can only be used after calibration is
unsecured. It sets the power supply to a calibration point that is entered with
CALibration:CURRent[:DATA] command. During calibration, two points
must be entered and the low-end point (MIN) must be selected and entered first.
CALibration:SECure:CODE
<new code>
This command enters a new security code. To change the security code, first unsecure
the power supply using the old security code. Then, enter the new code. The
calibration code may contain up to 12 characters over the remote interface but the first
character must always be a letter.
