Adjustment Is Recommended - Agilent Technologies U1251A User Manual

Performance Tests and Calibration 7
warranted beyond the 1- year calibration interval. Agilent
does not recommend extending calibration intervals beyond
2 years for any application.

Adjustment is Recommended

Specifications are only guaranteed within the period stated
from the last adjustment. Whatever calibration interval you
select, Agilent recommends that complete re- adjustment
should always be performed at the calibration interval. This
will assure that the U1251A/U1252A 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 but this does not guarantee that the
instrument will remain within these limits unless the
adjustments are performed.
Refer to the section "To Read the Calibration Count" on
page 153 and verify that all the adjustments have been
performed.
