by entering the correct security code. Refer to
“Calibration” on page 58 for more detailed procedures to
unsecure or secure the power supply.
Agilent calibration services
When your power supply is due for calibration, contact your
local Agilent Service Center for a low- cost calibration. The
Agilent E3640A, E3641A, E3642A, E3643A, E3644A, and
E3645A power supplies are supported on calibration
processes which allow Agilent to provide this service at
competitive prices.
Calibration interval
Recommended calibration interval for this power supply is
1 year. This will ensure that your power supply remains
within specification for the next calibration interval. Agilent
does not recommend extending calibration intervals beyond
1 year for any application. This criterion for re- adjustment
provides the best long- term stability.
