GENERAL.
2-5
a.
If possible operate the pyrometer and thermocouple tester in a sheltered area where there are no extremes of
temperature, moisture, or dust-laden wind. Under these moderate conditions the inspection and service intervals can be
reduced.
b.
When moving the tester from one normal ambient temperature to another in preparation for a test, allow it to
stabilize at the new temperature for 15 minutes before commencing the tests. Protect the pyrometer and thermocouple
tester when not in operation by keeping it in a sheltered area.
c.
After the completion of a test use a soft cloth to wipe the accumulated dust and finger prints off of the instrument
panel and viewing glass on the voltmeter. With the tester resting on a bench top and the instrument panel approximately
level adjust the voltmeter's zero adjust so that the pointer is coincident with the zero mark.
