Chapter 3 Maintenance; Probe Tip - Alnor 9870 Owner's Manual

CHAPTER 3
Maintenance
The Model 9870 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 meter.
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 then blow it off
with a gentle stream of air. Never use heat to dry
the probe.
Allow the sensor to dry thoroughly before use.
