Calibration Commands
See chapter 3 “Calibration Overview”, starting on page 58 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 .
