OPERATING INSTRUCTIONS
Power on and off:
1. Pull the trigger to turn on power. The LCD shows read-
ings from last measurement.
2. Auto Power Off (APO) function: Leave the meter with-
out operation for 10 seconds, power turns off automati-
cally.
Manual Single and Continuous Mode:
1. The meter is default to manual mode. Pull the trigger to
turn on power. Aim at the object, and quickly pull the
trigger to measure. When the LCD shows readings and
“HOLD” sign, single measurement is completed. Leave
the meter without operation for 10 seconds, power turns
off automatically.
2. Hold the trigger to measure continuously. Reading
changes every 0.25 second until the trigger is released.
At the mean time, LCD shows last reading and “HOLD”
sign.
Auto Continuous Mode:
The meter is default to manual mode. Press “APO” key.
Auto power off function will be cancelled, and auto con-
tinuous mode is activated. No need to hold the trigger, the
meter measures automatically. LCD will not show
“HOLD” sign and reading changes every 0.25 second
Press “APO” key again returns to manual mode.
Emissivity, Hi/Lo Limit Setting and MAX/MIN:
Power on. Press “SET” key to enter setting mode and use
the same key to go to next step, following as the cycle:
ε

ALM Hi
: High Limit Alarm Function:
Use

or
▼
to adjust.
When reading is higher than
setting, beeper makes brief
beeping sound, and LCD shows “ALM Hi”
sign.
ALM Lo : Low Limit Alarm Function: Use
▲
or
▼
to adjust. When reading is lower than setting,
beeper goes off a long beep, and LCD shows
“ALM Lo” sign.
MAX
: MAX shows the highest reading during
continuous measurement.
MIN
: MIN shows the lowest reading during con-
tinuous measurement.
Measuring mode: After the settings and displays, the meter
returns to measuring mode and ready for use.
※
Setting has to be completed by finishing the whole
process and return to measuring mode. If users need to
exit setting mode in the middle of process, pull the trig-
ger will skip setting and goes to measuring mode. Be
aware that the previous setting is not saved.
※
APO function is off in setting mode.
OPERATION
1. Take the protective cap off and then pull the trigger to
turn on the meter.
2. Point the lens at the object whose temperature is to be
measured.
3. Aim at the object, and quickly pull the trigger to meas-
ure. When the LCD shows readings and “HOLD” sign,
single measurement is completed.
4. Hold the trigger to measure continuously. Reading
changes every 0.25 second until the trigger is released.
At the mean time, LCD shows last reading and “HOLD”
sign.
5. Put the cap back on to extend sensor life and to avoid
damages from inappropriate use of laser pointer.
※
Although the field of measurement (or Field of View)
and the spot almost coincide, actually the field of meas-
urement corresponds to the diameter for 90% optical
response. The object whose temperature is to be meas-
ured needs to be larger than the measurement diameter
(spot of size) by an adequate margin at least 1.5 to 2
times larger.
MEASUREMENT CONSIDERATIONS
1. Theory of Measurement
Every object emits infrared energy in accordance with
its temperature. By measuring the amount of this radiant
energy, it is possible to determine the temperature of the
emitting object.
2. About Infrared
Infrared radiation is a form of light (electromagnetic ra-
diation), and has the property that it passes easily-
through air while it is easily absorbed by solid matter.
With an emission thermometer which operates by de-
tecting infrared radiation accurate measurement is pos-
sible, irrespective of the air temperature or the meas-
urement distance.
3. Emission Thermometer Structure
Infrared radiation which has been emitted from the ob-
ject is focused upon an infrared radiation sensor, via an
optical system. This includes a lens which is transparent
to infrared radiation. And 5.3µm cut off filter. The out-
put signal from the infrared radiation sensor is input to
an electronic circuit along with the output signal from a
standard temperature sensor (Thermopile).
4. Emissivity
All objects emit invisible infrared energy. The amount
of energy emitted is proportional to the object's tem-
perature and its ability to emit IR energy. This ability,
called emissivity, is based upon the material that the
object is made of and its surface finish. Emissivity val-
ues range from 0.10 for a very reflective object to 1.00
for a black body. Factory set emissivity value of 0.95,
which cover 90% of typical applications.
MAINTENANCE
Trouble Shooting
1. If the surface of the object is covered by frost or other
material, clean it to expose the surface.
2. If the surface to be measured is highly reflective, apply
masking tape or matt finish black paint to the surface.
3. If the meter seems to be giving incorrect readings check
the sensing tip. There may be condensation or debris
obstructing the sensor; clean it by following instruction.
Battery Replacement
1. Power is supplied by a 9 volt “transistor” battery.
(NEDA 1604, IEC 6F22).
2. Pull off battery cover “ ”.
3. Remove the battery cover by gently sliding it towards
the bottom of the meter.
4. Remove and disconnect the old battery from the meter
and replace with a new unit. Wind the excess lead
length and put the top of battery toward the lower side
of the battery chamber.
5. Put on the battery cover.
6. When battery is installed, the meter turns on automati-
cally to check the battery conditions. Power will turn off
automatically after 10 seconds without operation.
Cleaning
Periodically wipe the case with a damp cloth and deter-
gent, do not use abrasives or solvents.
