Agilent Technologies Calibration Services
When your instrument is due for calibration, contact your local
Agilent Service Center for a low-cost recalibration. The 34970A is
supported on automated calibration systems which allow Agilent to
provide this service at competitive prices.
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 does not recommend
extending calibration intervals beyond 2 years for any application.
Adjustment is Recommended
Whatever calibration interval you select, Agilent recommends that
complete re-adjustment should always be performed at the calibration
interval. This will assure that the 34970A 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 feature ( see page 69 ) to verify that all
adjustments have been performed.
