Verification and Calibration - B

Performing the Calibration Procedure

NOTE: The calibration procedure can only be performed using the SCPI language commands. Use either the front panel Address key to access the LANG command, or use the SYSTem:LANGuage command to change the programming language to SCPI.

Table B-1 lists the equipment required for calibration. Figure B-1 shows the test setup.

You do not have to do a complete calibration each time. If appropriate, you may calibrate only the voltage or current and proceed to "Saving the Calibration Constants". However, the voltage or current calibration sequence must be performed in its entirety. The following parameters may be calibrated:

♦voltage programming and measurement

♦overvoltage protection (OVP)

♦current programming and measurement

♦negative current programming

♦low range measurement

♦ac current measurement
