*SAV { 0| 2 | ……|9 }
This command stores the present state of the power supply, which can store 10 sets of operating states from 0 to 9. The state
storage features in saving the states or values of INST[:SEL], VOLT[:IMM], CURR[:IMM], OUTP[:STAT], OUTP:TRAC,
TRIG:SOUR and TRIG: DEL.
*RCL { 0| 2 | ……|9 }
This command recalls a previously stored state. To recall a state, you must store it in advance. When recalling a stored state,
you must use the same memory location used previously to store the state.
4.31 Calibration Commands
CALibration:COUNt?
This command queries the power supply to determine the number of times it has been calibrated.
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, which are then stored in internal memory.
CALibration:CURRent:LEVel {MINimum | MAXimum}
Before using this command, you must select the output which is to be calibrated by 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 calibration 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 with the old security
code. Then, enter the new one.
CALibration:SECure:STATe {OFF | ON>}, <code>
This command secures or unsecures the power supply for calibration.
CALibration:SECure:STATe?
This command queries and returns the current secured state for calibration of the power supply. The returned parameter is
“0” (unsecured) or “1” (secured).
CALibration:STRing <quoted string>
This command records calibration information about your power supply.
For example, you can store such information as the calibrator and the calibration date.
CALibration:STRing?
This command queries the calibration message and returns a quoted string.
CALibration:VOLTage[:DATA] <numeric value>
This command can only be used after calibration is unsecured. It enters a voltage value of a selected output that you
obtained by reading an external meter. You must first select a calibration level (CAL:VOLT: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 voltage calibration constants, which are then stored in internal memory.
CALibration:VOLTage:LEVel {MINimum | MAXimum}
Before using this command, you must select the output which is to be calibrated by 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:VOLTage[:DATA] command. During calibration, two calibration points must be entered and the low-end point
(MIN) must be selected first.
