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 adeq uate 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.
