Performing the Calibration Procedure
Table B-1 lists the equipment required for calibration. Figure B-1 shows the test setup.
NOTE: You do not have to do a complete calibration each time. You may calibrate only the
voltage or current and proceed to "Saving the Calibration Constants." However, before
you calibrate OVP, you must first calibrate the output voltage.
The following parameters may be calibrated:
♦ ac output voltage
♦ output voltage measurement
♦ overvoltage protection (OVP)
♦ ac output current
♦ output current measurement
♦ output impedance
Before calibrating the output impedance, you must first calibrate the output voltage and the output curent.
Front Panel Calibration Menu
The Entry keypad is used for calibration functions.

Display Command Function
CAL ON <value> Turns calibration mode on when the correct password
value is entered.
CAL OFF Turns calibration mode off
CAL:LEV <char> Advance to next step in sequence (P1, P2, P3, or P4).
CAL:DATA <value> Input a calibration measurement.
CAL:VOLT:OFFSET Begin voltage offset calibration
CAL:VOLT:DC Begin dc voltage calibration sequence
CAL:VOLT:AC Begin ac voltage calibration sequence
CAL:VOLT:PROT Begin voltage protection calibration
CAL:CURR:AC Begin ac current calibration sequence
CAL:CURR:MEAS Begin current measurement calibration sequence
CAL:IMP Begin output impedance calibration sequence
CAL:SAVE Saves the calibration constants in non-volatile memory.
CAL:PASS <value> Set new calibration password.
Notes:
