The thermometer is a non-contact infrared thermometer.
There are many mathematical modes for the Infrared
function. Please remember to keep away from children and
don’t use it for safety related applications.
(Default Screen)
Simply aim the thermometer at
the measure target with Lens (○7)
and press Meas. key (○9) to
display the surface temperature.
The Distance:Spot is 20:1.
Please make sure the target area is within the field of
view.

After measure high temp, the probe may remain HOT for a while.
** The thermometer will automatically shut off if left idle for more than 60sec, unless in PRB mode. (In PRB mode, it will shut off if
left idle for more than 12 minutes.)

CAUTION
1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEAM–PERMANENT EYE DAMAGE MAY RESULT.
2. USE EXTREME CAUTION WHEN OPERATING THE LASER.
3. NEVER POINT THE DEVICE TOWARDS ANYONE’S EYES.
4. KEEP OUT OF REACH OF ALL CHILDREN.
STORAGE & CLEANING The thermometer should be stored at room temperature between -4~149°F (–20 to +65
o
C).
The sensor lens is the most delicate part of the thermometer. The lens should be kept clean at all times, care should be taken when
cleaning the lens using only a soft cloth or cotton swab with water or medical alcohol. Allowing the lens to fully dry before using the
thermometer. Do not submerge any part of the thermometer.
LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the settings of
HAL and LAL.
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient
temperature. ‘Er3’ is displayed when the ambient temperature exceeds 32°F (0oC) or 122°F
(+50oC). The thermometer should be allowed plenty of time (minimum 30 minutes) to stabilize
to the working/room temperature.
For all other error messages it is necessary to reset the thermometer. To reset it, wait for auto power
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.
BATTERIES
The thermometer incorporates visual low battery indication as follows:
‘Battery OK’: measurements
are possible
‘Battery Low’: battery needs to be
replaced, measurements are still possible
‘Battery Exhausted’: measurements are
not possible
When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced immediately with AAA, 1.5V batteries.
Please note: It is important to turn the instrument off before replacing the battery otherwise the thermometer may malfunction.
Dispose of used battery promptly and keep away from children.

Caution: The measure range is for thermometer only. User should choose proper probe types for different kinds of
application. Please make sure the target to be measured will not exceed the temperature range of the probe to
avoid permanent damage of the thermocouple probe.
EMC/RFI
Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per
meter, but the performance of the instrument will not be permanently affected.
