Tro u b l e s h o o t i n g
No display or erratic display: check the battery for proper voltage and
tight contact at the battery clip. Ensure the unit is at the specified
operating temperature.
Constant or spurious over-load (OL) display: check battery voltage.
Check for electromagnetic interference (EMI). To check for EMI, move
the unit to an open area, away from high voltage and radio or radar
transmitting sources.
Errornous temperature readings: inspect the infrared lens for blockage
or contamination. Follow cleaning instructions. Check battery for proper
voltage and tight fit in the battery clip.
