WARNING: Before turning on the in-
strument, ensure that it has been
installed in accordance with the In-
s
tallation Instructions outlined in
Cha
pter 1 of the User's Manual.
This performance procedure is intended for:
— checking the instrument's specification.
— incoming inspection to determine the ac-
ceptability of newly purchased
instruments and recently recalibrated
instruments.
— checking the necessity of recalibration
after the specified recalibration intervals.
NOTE: The procedure does not check every
facet of the instrument's calibration;
rather, it is concerned primarily with
those parts of the instrument which are
essential for determining the function of
the instrument.
It is not necessary to remove the instrument
cover to perform this procedure.
Power up your instrument
at least 30 minutes before
checking to let it reach
normal operating
temperature. Failure to do
so may result in certain test steps not meeting
equipment specifications.
