Closed-Case Electronic Calibration The power supply features closed- case electronic calibration since no internal mechanical adjustments are required for normal calibration. The power supply calculates correction factors based upon the input reference value you enter. The new correction factors are stored in non-volatile memory until the next calibration adjustment is performed. (Non-volatile memory does not change when power has been off or after a remote interface reset.)

Agilent Technologies Calibration Services

When your power supply is due for calibration, contact your local Agilent Technologies Service Center for a low-cost calibration. The Agilent E3632A power supply is supported on calibration processes which allow Agilent Technologies to provide this service at competitive prices.

Calibration Interval

The power supply should be calibrated on a regular interval determined by the accuracy requirements of your application. A 1-year interval is adequate for most applications. Agilent Technologies does not recommend extending calibration intervals beyond 1 year for any application. Agilent Technologies recommends that complete re-adjustment should always be performed at the calibration interval. This will increase your confidence that the Agilent E3632A will remain within specification for the next calibration interval. This criteria for re-adjustment provides the best long-term stability.
