Calibration

Calibration Description ............................................................... 36

Calibration Procedure ................................................................. 37

This chapter includes calibration procedures for the Keysight E4360
Series Solar Array Simulator. Instructions are given for performing the
procedures from either the front panel or a controller over the remote
interface.

Refer to the “Equipment Required” section in chapter 2 for a list of the
equipment required for calibration. Also refer to “Measurement
Techniques” for information about connecting the voltmeter and current
shunt.

NOTE

Perform the verification tests before calibrating your solar array
simulator. If the solar array simulator passes the verification tests, the
unit is operating within its calibration limits and does not need to be re-
calibrated.

Calibration Interval

The recommended calibration interval for Keysight E4361A/E4362A
output modules is one year. Keysight E4360A SAS mainframes do not
require calibration.
