'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).

displayed when the ambient temperature of the
thermometer EXCEEDS 0
°
C (32
°
F) OR +50
°

BATTERIES
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
J the battery and turn on. If the error message remains
please contact the Service Department for further
assistance.
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.
The thermometer incorporates visual low battery indication (for the lower battery) as
follows:
'Battery OK':
measurements
are possible
'Battery Low': battery needs to
be replaced, measurements
are possible
BATTERY REPLACEMENT
/i I I'
'Battery Exhausted':

not possible
When the 'Low Battery' icon indicates the battery is low, the battery should be replaced
immediately with a CR2032 lithium cell. The battery is located under the twist cover at
the rear of the thermometer. Please note: It is important to turn the instrument off
before replacing the battery otherwise the thermometer may malfunction.
