Calibration interval
A 1- year interval is adequate for most applications. Accuracy
specifications are warranted only if adjustment is made at
regular calibration intervals. Accuracy specifications are not
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. Agilent recommends that
re- adjustment should be performed during the calibration
process for best performance. This will ensure that the
instrument 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 “Calibration Count” on page 49 and verify that
all the adjustments have been performed.
