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 E3631A 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 E3631A will remain within
specification for the next calibration interval. This criteria for re-adjustment provides
the best long-term stability.
