Other recommendations for calibration
Specifications are only guaranteed within the specified
period from the last calibration. Agilent recommends that
readjustment should always be performed at whatever
calibration interval you select. This will ensure that the
instrument remains within its specifications until the next
calibration. This calibration criterion provides the best
long- term stability.
During performance verification tests, only the performance
data is collected; these tests do not guarantee that the
instrument will remain within the specified limits. The tests
are only for identifying which functions need adjustment.
Please refer to the “Calibration Count” on page 27 and
verify that all adjustments have been performed.
