Adjustments
Introduction
This chapter contains procedures for adjusting the calibration constants in the
Keysight E1412A multimeter. See the section titled "Calibration Interval" for
recommendations on time intervals.
Closed-Cover Electronic Calibration
The Keysight E1412A Multimeter features closed-cover electronic calibration.
There are no internal mechanical adjustments. The multimeter will measure the
applied input when performing a range calibration, then calculate correction
factors for the range based on this known input reference value. The new
correction factors will be stored in non-volatile memory for use until the next
time a calibration adjustment is performed. (The non-volatile memory does not
change when power is turned off or after a remote interface reset.)

Calibration Interval
The Keysight E1412A Multimeter should be calibrated on a regular interval
determined by the measurement accuracy requirements of your application. A 90
day interval is recommended for the most demanding applications, while a 1 year
Do not perform any of the following adjustments unless
