Handhold infrared thermometer with
thermocouple socket
The thermo meter is a non-cont act
infrared thermo meter. 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.
FUNCTION
Press Emissivity key (○
1) for setting the emissivity.
Press Emissivity key (○
1), then p ress Up key ( ○
4) or Down key ( ○
2) to set the emissivity, then press Mode ke
y
(○
5) to confirm it. The emissivity can be changed from 0.10 (10E) to 1 (100E).
Press Mode key (○
5) for scrolling more display function as follows.
Here will show the emissivity data. (The default emissivity is 0.95.)
Press Mode key ( ○
5) for the Maximum (MAX), Minimum (MIN), Different between MAX and MIN (DIF) and
Average (AVG) modes. Durin
g
the measurement, the special modes readin
g
will be displa
y
ed beside the
mode icon.
Press Up key (○
4) or Down key (○
2) key to change the High Alarm (HAL) or Lo Alarm (LAL), then press Meas.
key (○
9) to confirm it. For example: When the reading 26.9oC < LAL 27 oC, the Low icon will flash and you will hear
a beep sound.
(Only for TN40ALC). Connect the thermocouple with Thermocouple socket (○
10 ) and put the
probe in/on the tar
g
et,
the thermometer will disp lay the temperature automatically
without pressin
g
an
y
button. To see the minimum or
maximum data during the probe measurement, please hold down the Up key (○
4) or Down key (○
2).
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.)
ADD VALUE
Press Up key ( ○
4) for LOCK mode ON/OF F. The lock mode is particularl
y
useful for continuous
monitoring of temperatures for up to 60 minutes.
In MAX, MIN, DIF, AVG
mode: Press Down key (○
2) for oC or oF transferred.
and press Up key (○
4) for backlight function ON/OFF.
In all modes: First
hold on the Meas. key
(○
9) and press Down key (○
2) for laser function ON/OFF.
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 ALLCHILDREN.
STORAGE & CLEANING The thermometer should be stored at room temperature between –20 to +65oC (-4~149°F).
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 us ing only a soft c loth or c otton swab wit h wat er or m edical alcohol. A llowing the le ns to f ully dry before us ing t he th ermometer. 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 dis played whe n the am bient te mperature ex ceeds 0oC (32°F) or +50 oC (122°F). Th e therm ometer
should be allowed plenty of time (minimum 30 minutes) to stabilize to the working/room temperature.
「 」
Error 5~9,,for all other error messages it is necessary to reset the thermometer. To reset it, wait f or auto power
off, r emove th e b attery a nd w ait f or a mini mum of o ne min ute, rei nsert the ba ttery a nd turn on. If the er ror
message remains please contact the Service Department for further assistance.
「 」「 」 ‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the measurement range.
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.

Note: Under the electromagnetic field of 3V/m from 200 to 600 MHz, the maximum error is 10 oC (18 oF).
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.
Caution: To avoid electric shock and thermometer damage, do not measure live circuit where voltage exceeding 24V AC RMS or
60V DC with 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.
