Calibration Procedures 1
Keysight U1281A/U1282A Service Guide 19
Recommended adjustment
Specifications are only guaranteed within the period stated from the last
adjustment. Keysight recommends that re-adjustment should be performed
during the calibration process for best performance. This will ensure that the
multimeter will remain within the specifications for the next calibration interval.
This criterion for the re-adjustment provides the best long-term stability.
Performance data are measured during the “Performance Verification Tests” on
page 27, but the multimeter is not guaranteed to remain within these limits unless
the adjustments are performed.
See “Calibration Count” on page 55, and verify that all the adjustments have been
performed.
