LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
BATTERIES
The thermometer has two separate batteries. The battery closer to the
side of the laser beam output is for laser operation only. The other
battery is designated for temperature measurements. The
thermometer can still measure temperature properly, even without the
laser battery.
'Hi' or 'Lo' is displayed when the temperature being
measured is outside of the range of the instrument,
'Hi' when higher than +250°C (482°F) and 'Lo'
when lower than –55°C (-67°F).
'Er2' is displayed when the thermometer is
exposed to rapid changes in the ambient
temperature. 'Er3' is displayed when the ambient
temperature of the thermometer EXCEEDS 0°C
(32°F) OR +50°C (122°F). In both cases you should
allow plenty of time (minimum 30 minutes) for the
thermometer to stabilize to the working/room
temperature.
For all other error messages it is necessary to reset
the thermometer. To reset it, turn the instrument
off, remove the battery and wait for a minimum of
one minute, reinsert the battery and turn on. If the
error message remains please contact the Service
Department for further assistance.
