11.2. Balance Shaft Check
Perform the following:
•
Clean the heat chamber before performing this check (See section
). This keeps debris from falling into the balance shaft.
•
Turn the instrument off.
•
Use the supplied tweezers to remove the pan support; place the tweezers’ tips under
the pan support and pry the pan support straight up and out of the balance stem.
Be
careful; excess force on the balance can result in costly repairs.
•
Remove the balance cover.
•
Look down the balance shaft to the balance and make sure that the area is free of
debris.
•
Reinstall the balance cover.
•
Gently but firmly install the pan support into the balance stem.
11.3. Heater Cleaning
Perform a heater cleaning only if a Temperature Calibration Kit is
available. If not, contact AZI Customer Service to arrange for the
instrument’s return to the factory for cleaning and calibration.
An oven cleaner such as “Easy-Off” should not be used on the
aluminum shroud as it is corrosive and will remove the coating and
pit the aluminum.
Cleaning frequency will vary depending on the application and frequency of use. We
recommend that you establish a periodic cleaning schedule to ensure
instrument-to-instrument correlation and performance. Call AZI Customer Service if you
have any questions.
Testing of some materials may cause a brown discoloration behind the heater and on the
inside of the heater shroud. This darkening affects results as heat is absorbed rather than
reflected from the heater shroud onto the sample. However, the “browned” condition may
be allowed to remain on the heater shroud and heater box if test results can be
maintained within an acceptable range.
Cleaning procedure:
•
The following cleaning materials are needed:
o
Cleaning solution, such as Formula 409
®
, in a spray bottle.
o
Cloth and/or paper towels
o
Small stiff bristle brush, such as a toothbrush or acid brush
o
Cotton swabs or cotton tipped applicators
o
Water for cleaning and wiping shroud and heater after cleaning
o
Small Phillips head screwdriver (if you elect to remove the shroud)
•
Turn the instrument off
•
Remove the power cord.
•
Wait for the instrument to cool down to room temperature.
