CHAPTER THREE
Maintenance
The Model 9880 requires very little maintenance to
keep it performing well.
Probe Tip
Periodically inspect the probe tip to ensure that it is
clean. Dust and oil deposits on the tip and sensor
decrease the accuracy of the Model 9880.
CAUTION
The meter must be switched OFF for cleaning.
Do not use high-pressure air, strong solvents,
or brushes to clean the sensor tip; damage to
the sensor could result.
To remove dust, blow it off with a gentle stream of
air or rinse it off with a gentle stream of water. To
remove a combination of dust and oil, rinse the
probe tip in isopropyl alcohol and them blow it off
with a gentle stream of air. (Do
not
use isopropyl
alcohol which contains Lanolin.)
Never
use heat to
dry the probe.
Touching the probe with any object is not
recommended. Allow the sensor to dry thoroughly
before use.
