Performance Tests and Calibration 6
Agilent U1251B/U1252B User’s and Service Guide 109
Adjustment is Recommended
Specifications are only guaranteed within the period stated
from the last adjustment. Agilent recommends that
readjustment should be performed during the calibration
process for best performance. This will assure that the
U1251B/U1252B 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 139 and verify that all the adjustments have been
performed.
