Appendix B
Verification and Calibration
Verification	94
Calibration	113

	The verification procedures described in this appendix verify that the
	power supply is operating normally and is within published
	specifications.
	This appendix also includes calibration procedures for the Agilent
	N5700 power supplies. Instructions are given for performing the
	procedures from a controller over the GPIB.
	Perform the verification tests before calibrating your power supply. If the power
NOTE
	supply passes the verification tests, the unit is operating within its calibration
	limits and does not need to be re-calibrated.

	The recommended calibration interval for Agilent N5700 power
	supplies is one year.
