5. Operation Instructions
5.1 Manual Measurement
To measure temperature, point the temperature sensor
right toward the object, and then pull the trigger to start it.
Please do pay attention to the optical resolution(D:S)
and the observation view. The laser is used only for the
aiming purpose.
Gently touch the MODE key on the panel to switch the
flashing symbol at the lower-left corner of the panel
cyclically in the shown order.
5.2 Degree Celsius/ Fahrenheit Toggling
Gently touch the °C/°F key on the panel to conveniently
toggle between degree Celsius and degree Fahrenheit.
5.3 View Max/Min/ Ave/Diff Temperature
5.4.1 When using K-type probe for measuring
temperature, please do properly insert the K-type
probe into the K-type standard temperature base
at the lower part of the sensor.
5.4.2 Pull the trigger on the sensor, wait for the sensor to
be switched into the measuring mode, and then
gently touch “SEL” key on the sensor for a short
moment. The sensor will then be switched into the
mode of K-type temperature measurement (as
shown in the figure).
Please do not connect the attached probe to a
circuit with power on.
There might be a difference between the measured
values for the same object under the infrared mode
and the probe measurement mode. The reason is
due to the emissivity of the object being tested.
For details, please refer to the emissivity
comparison table.

5.4 Connect the Temperature Probe
5.5.1 Emissivity is a measure of the radiation energy of
the corresponding material. Most organic material
and painted surfaces or oxidized surfaces have an
emissivity of 0.95. The preset emissivity of the
temperature sensor is 0.95. The readings might
not be accurate when measuring shining metal
surfaces. To correct the readings, you can use
opaque photo paper or black paint to cover the test
surface (< 148°C /300°F). Wait until the
temperature of the photo paper or paint is the
same as that of the covered surface. Then,
measure the temperature of the photo paper or the
surface of the paint.
