button is for selection and “POWER” button is for confirmation.
A. Trigger mode: Auto/Manual
Short press the “SELECT” button and select Auto/Manual
Select Auto, the automatic trigger mode, when the power value is greater than the selected trigger value,
the measurement is automatically started.
Select Manual, short press the “POWER” button start a measurement and end a measurement.
Short press the “POWER” button to confirm and start another setting. Choose “Auto”, the meter enters the
trigger power value setting interface; Select Manual, the meter enters the smooth setting interface.
Note: For the recording time is only 32 minutes, if the production line is very long and need a long time to
reach the UV Lamp position, the “AUTO” mode must be selected.
B. Trigger power: 5-50mW/cm² can be set
Short press the “SELECT” button to set the trigger power value and you can long press the button for
quick setting.
Short press the “POWER” button to confirm the setting and the meter enters the smooth interface.
C. Smooth processing
If the UV light source uses AC power supply, the frequency of the AC power will affect the accuracy of the
power measurement. Short press the "SELECT" button to select the power frequency of the light source.
OFF: this option can be selected if no smooth processing will be performed and the UV lamp is
powered with direct current
50HZ: this option must be selected if frequency of the alternating current is 50HZ
60HZ: this option must be selected if frequency the alternating current is 60HZ
Short press the “POWER” button to confirm the setting and enter the “Standard Selection” interface.
D. Standard Selection
Short press the “SELECT” button to select the standard
 LS-STD (Enterprise standard): The meter is calibrated according to enterprise standard.
 JJG 879-2015 (Chinese standard): The meter is calibrated according to Chinese standard.
Short press the “POWER” button to confirm the setting and the meter enters the “STOP” interface.
E. Factory default settings:
 Trigger mode: Manual
 Smooth: 50HZ

2. ON/OFF
1) In POWER OFF state, short press “POWER” button to power on the meter. After turning on the meter,
the meter displays the calibration coefficient, version number, manufacturing date, calibration date,
serial number, etc. and then enters the last measurement interface (STOP interface).
In the “STOP” interface, long press the “POWER” button to power off the meter.
2) In the “STOP” interface, the meter will automatically power off in 3 minutes without any operation.
3) In the automatic trigger measurement “Ready” state, the longest waiting time is 50 minutes. If the
measurement cannot be triggered within 50 minutes, it will automatically turn off.
3. Measurement
In the measurement mode, three operation states exist:
READY: Ready state; in the auto trigger mode, this means the meter is waiting for triggering to begin
a measurement.
RUN: Measuring state; this means the meter is collecting data.
STOP: Stop state, this means the data measurement finished.
In measurement mode, 4 kinds of display modes can be selected by using the “SELECT” button:
MAX: Maximum value (including the maximum value of energy, irradiance and temperature)
RT: Real-time value (including time, irradiance and temperature)
Irradiance curve: (Can only view in the “STOP” state)
Temperature curve: (Can only view in the “STOP” state)
1) Manual measurement mode: in the STOP interface. Short press the "POWER" button and then
short press the "SELECT" button to confirm the new measurement, clear the historical data (display
"-----"), automatically enter the measurement interface (RUN state) after 1s. Short press the

7-29-2020 Page 6 of 9
"POWER" button or after 32 minutes, the measurement is over and enter the STOP interface.
2) Automatic mode: After pressing the button to confirm the new measurement, the meter enter the
READY state to clear the historical data and wait for the trigger condition (Trigger power) to be met,
the energy display "----" and flashing. When the power value is greater than the set trigger power, the
trigger condition is met, enter the measurement interface (RUN state). When the recording time
reaches 32 minutes or the power value is less than the set trigger power, the measurement is
automatically ended and enters the STOP interface.
4. The last measurement data view
In the stop status, the interface displays the maximum value of the last measurement.
The maximum value, real-time value, irradiance curve and temperature curve can be viewed by pressing
"SELECT" button.
In the stop status, long press the " SELECT " key to clear the current test data.
5. USB communication
This meter has the function of 32-minutes data recording.

Shenzhen Linshang Technology Co., Ltd.
7-29-2020 Page 7 of 9
Recording period: 32 minutes
Irradiance data storage interval: 32 times /s, up to 61440 irradiance record data.
Temperature data storage interval: 2 times/s, up to 3840 temperature data
In the “STOP” mode, all recording data in the meter can be read, the curves can be displayed, data can
be exported into EXCEL and reports can be printed with the PC software.
VI. PC Software
The meter is equipped with a USB communication port and it can be connected to the computer with
plugging in the USB cable and starting the special PC software, and the data in the meter can be read.
The software has various functions, such as parameter configuration, data reading, UV irradiance curve
and temperature curve display, data irradiance export into EXCEL, temperature data export into EXCEL
and report generation.
The report generation and printing function should be specially explained. For test data, the software can
generate a report automatically and print, and if a PDF printer is installed, the electronic version report
can be printed in PDF format. This is convenient for the recording and archiving of test data.
Record data can be read by connect USB cable with computer directly (when the meter is connected to
the computer with USB port for the first time, you will be prompted to restart the computer so as to PC
load the driver automatically). Currently, the software supports Windows system.
