I. Product Introduction
Spectrum transmission meter uses an ultraviolet light source, an infrared light source and a visible light
source to illuminate the transparent material under test. The sensor detects the incident light intensity of
the three light sources and the light intensity after passing through the transparent material under test. The
ratio of the transmitted light intensity to the incident light intensity is the transmission, expressed as a
percentage.
Professionally used for optical transmission testing of various materials such as lenses, glass, coating
materials, organic materials, paints, etc.

III. Operation
1. Power on self-test
 Power on
Plug in the power supply and ensure there is no test sample under testing. Short press the " " button to
turn on the meter. The boot interface displays the version number and serial number of the meter and then
enters into the measurement interface.
 Power off
Short press the “ ” button to turn off the meter in the measurement interface; Long press the “ ” button
for 3s to turn off the meter in the setting interface.

in the measurement interface.
(1) In the Setup interface, the " " button is used to confirm the setting; the "Operation" button is used for
selection.
(2) Short press the "Operation" button to select the setting item:
A. Select "Language", short press " " button to enter the setting item you selected
a) Short press the "Operation" button to select Chinese/English:
b) Select "Chinese": the measurement interface is switched to Chinese;
c) Select "English": the measurement interface is switched to English;
d) Press the " " button to confirm the setting and return to select the setting item.
B. Select "Exit", short press the " " button to exit the setting mode and enters into the measurement
mode.
3. Measurement and operation
After powering on, the meter enters into the measurement interface, all transmission data is displayed as
100%. The test sample is placed on the test hole, the LCD screen displays the visible light of 380nm-
760nm, infrared light of 940nm and UV transmission of 365nm of the test sample;
As shown in the figure below: the visible light transmittance of the test sample is 95.7%, the infrared
transmission is 93.3% and the UV transmission is 81.8%.

4. Abnormal voltage prompt
Voltage> 5.7V or <4.7V, the meter enters into the abnormal voltage interface. The meter automatically
turns off after 2s; when the interface prompt appears, please follow the prompts to replace the appropriate
power supply.
IV. Features
1. UV transmission meter, infrared transmission meter, visible light transmittance meter, three functions
in one device.
2. Obtain the visible light transmittance of 380nm-760nm, 940nm infrared and 365nm UV transmission
by aligning the test hole just once.
3. Suitable for transmission test of lens, paint, glass, mobile phone lens, organic material, etc.
4. The meter has a real-time dynamic self-calibration function, which automatically calibrates to 100%
transmittance after powering on.
5. The minimum test sample size is ￠1mm.
6. Large LCD display, Chinese and English display interfaces can be selected.
V. Notes
1. The meter is self-testing and self-calibrating when it is turned on, please don’t place any test sample
in the test position, otherwise the self-calibration cannot be completed.
2. Avoid contact with corrosive materials and keep away from high temperature and high humidity

environment.
3. When there is no test sample, the display data occasionally cannot return to "100%". Just shut down
and restart the meter immediately for normal use，it does not affect the measurement accuracy.
4. When the meter is not in use, please turn it off.
5. When the interface displays abnormal voltage, please replace the power supply.
