Performing the Calibration Procedure

Verification and Calibration - B

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.

Shift

Cal

Press this key to access the calibration menu.

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:

value = a numeric value
char = a character string parameter
