Appendix C: Instrument Calibration
Over time, the active components in the FieldFox age and the performance may
degrade or drift. To ensure that the FieldFox is performing to the published
specifications, you should have an instrument calibration performed
periodically.
How Often Should I Get an Instrument Calibrated?
You determine the calibration period which best meets your requirements.
However, a 12 month calibration cycle is appropriate for most users.
There are two things to consider: performance drift and connector wear.
The instrument specifications are set to consider the performance drift that may
occur over a 12 month period. Therefore, getting the instrument calibrated at 12
month intervals ensures that the analyzer maintains performance within the
operating specifications. If you need the analyzer to maintain more consistent
operation, you may want to have the instrument calibrated more often.
Connector wear is a bigger factor and depends on the number of connections
that are made. The test ports become noticeably worn after 500 to 700
connections. This could represent about 12 months with average use. With more
frequent connections, the calibration cycle should be sooner. You can extend the
time between calibrations and thereby save money by using connector savers and
by performing proper Connector Care. Learn more on page 213.
How Do I Get an Instrument Calibrated?
To get your Agilent instrument calibrated, send it to one of the Agilent
Technologies service centers. Please visit this website to learn how:

What Are My Choices of Instrument Calibration?
The following types of instrument calibration are available from Agilent
Technologies service center:
Includes the test data from the calibration and the certificate of
calibration, stating the instrument has been calibrated and is
operating within the published specifications.
Includes the test data from the calibration and the certificate of
calibration, stating the instrument has been calibrated using a
process in compliance with ANSI Z540.1 and is operating within the
published specifications.
Includes the test data from the calibration and the certificate of
calibration, stating the instrument has been calibrated using a
process in compliance with ISO 17025 and is operating within the
published specifications.
