in accordance to our
published specifications and
with standards traceable to
the National Institute of
Standards & Technology
(NIST
).
DID YOU KNOW?
CALIBRATION
You will find in this manual a copy of the
"Certificate of Calibration". It is recommended that
you have this instrument recertified at least once
per year. Associated Research, Inc. recommends
you use "Calibration Standards" that are NIST
traceable or traceable to agencies recognized by
NIST to keep this instrument within published
specifications. Unless necessary, do not
recalibrate the instrument within the first 12
months.
End user metrology standards or practices may
vary. These metrology standards determine the
measurement uncertainty ratio of the calibration standards being used. Calibration
adjustments can only be made in the Calibration mode and calibration checks or
verifications can only be made while operating in Test mode.
NOTE:
Verification should be performed before and after calibration.
Calibration effects will only be noticeable after exiting calibration mode.
10.1 Warranty Requirements
Associated Research, Inc. offers a standard three-
year manufacturer’s warranty. This
warranty can be extended an additional two years provided that the instrument is
returned each year to Associated Research, Inc. for its annual recertification. In order
to be eligible for the extended warranty instruments must be returned to Associated
Research, Inc. for certification service at least once every twelve months.
A return material authorization number (RMA) must be obtained from Associated
Research, Inc. before returning this instrument for calibration. To obtain an RMA
number or for information regarding our warranty, please contact our customer
support representatives at 1-800-858-TEST (8378) or setup an RMA online at
