Chapter 4 Calibration Procedures
Calibration Interval

Calibration Interval
The instrument should be calibrated on a regular interval determined by
the measurement accuracy requirements of your application. 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 Technologies does not recommend extending calibration
intervals beyond 2 years for any application.
Adjustment is Recommended
Whatever calibration interval you select, Agilent Technologies
recommends that complete re-adjustment should always be performed
at the calibration interval. This will assure that the Agilent 33250A
will remain within specification for the next calibration interval.
This criteria for re-adjustment provides the best long-term stability.
Performance data measured using this method can be used to extend
future calibration intervals.
Use the Calibration Count (see page 70) to verify that all adjustments
have been performed.
