Maintenance and Performance Checks 5-4
Environmental
Conditions
Tests should be performed under laboratory conditions having an
ambient temperature of 25
o
C
"
5
o
C and at relative humidity of less
than 80%. If the instrument has been subjected to conditions outside
these ranges, allow at least one additional hour for the instrument to
stabilize before beginning the adjustment procedure. Always perform
a self-test sequence before commencing with the performance
checks. The self-test, if executed without any failure, ensures proper
operation of the generator. If self-test failures have been
encountered, the instrument first needs to be serviced and the
source of failure removed. Instructions on how to perform self-test is
given later in this chapter in the Self-Test section.
Warm-Up Period
Most equipment is subject to a small amount of drift when it is first
turned on. To ensure accuracy, turn on the power to the Model
3151/3151A and allow it to warm-up for at least 30 minutes before
beginning the performance test procedure.
Initial Instrument
Setting
To avoid confusion as to which initial setting is to be used for each
test, it is required that the instrument be reset to factory default
values prior to each test. To reset the Model 3151/3151A to factory
defaults, send either of the following commands:
RESet, or *RST.
