For Model with thermocouple socket
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 (
8
) and press Meas. key (
6
) to
display the surface temperature. The Distance:Spot is 50:1. The two laser points are the reference for the target spot
size.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 press Up key (
4
) or Down key (
2
) to
set the emissivity
, then press Mode key
(
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. During the measurement, the special modes reading will be displayed 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 (
6
) to confirm it. For example: When the reading 26.9
o
C < LAL 27
o
C, the Low icon will flash and you will hear
a beep sound.
Connect the thermocouple with Thermocouple socket (
11
) and put the probe in/on the target, the thermometer will
display the temperature automatically without pressing any 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.ADD VALUE
Press Up key (
4
) for
LOCK mode
ON/OFF.
The lock mode is particularly useful for continuous
monitoring of temperatures for up to 60 minutes.
In MAX, MIN, DIF, AVG
mode:
Press Down key (
2
) for
o
C
or
o
F transferred.
and press Up key (
4
) for
backlight function
ON/OFF.
In all modes: First
hold on the Meas. key
(
6
)
and press Down key (
2
) for
laser function
ON/OFF.
(With flash light be turned on in the same time as laser )
CAUTION
1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE TWO LASER BEAMS–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 –20 to +65
o
C (-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 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 0
o
C (32°F) or +50
o
C (122°F). The thermometer
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 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.
‘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.
