CAUTION
High internal temperatures may damage the gauge’s
electronic components. To reduce the risk of damage,
DO NOT allow the gauge to sit on hot asphalt for
extended periods.
If the internal temperature of the gauge reaches a level
that is considered excessive, the beeper will sound and
the warning message Internal temp. high will show on
the display.
Allow the gauge to cool will be displayed. The gauge
should be taken to a shady or air-conditioned
environment and allowed to cool before continuing. If
measurements are performed before the gauge is
allowed to cool, the warning symbol is displayed.
NOTE
Before using the gauge, inspect the protective cover of
the bottom surface of the gauge’s sensor. Ensure that the
cover is in good condition, and has no deep scratches or
buildup of material. If necessary, replace the cover as
described on page A–8.
The gauge includes a replaceable protective cover that
protects the bottom surface of the gauge’s sensor
assembly against wear and provides thermal protection
for the gauge’s internal components. To prevent
damage to the gauge, DO NOT operate the gauge
without the protective cover.
