V. Operation
1. Parameter setting
In OFF mode, long press the “POWER” button for 3 s and enter into the setting mode:

A. Trigger mode: (the measurement mode of Auto and Manual)
Short press “▲” or “▼”to choose Auto/Manual
Choose “Auto”-the auto trigger mode, the meter will start and stop automatically.
Choose “Manual”-the measurement will start and stop manually.
Short press the “ENTER” key and enter into the next setting interface. If Auto mode is selected, next
setting interface is trigger threshold value. If manual mode is selected, next setting interface is the smooth
process.
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 threshold (Trigger power: 1-50mW/cm² can be set)
Short press “▲” or “▼” to set the trigger threshold.
Short press the “ENTER” button and enter into the smooth process.
C. Smooth Processing (Smooth: OFF/50HZ/60HZ)
If the UV lamp is powered with alternating current, the frequency of alternating current will influence the
accuracy of the irradiance measurement. Short press “▲” or “▼”to select the power supply 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 of the alternating current is 60HZ
Short press the “ENTER” button to confirm the setting and the meter enters the “Standard Selection”
interface.
D. Standard Selection
Short press the “ ” button or “ ” 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 “ENTER” button to confirm the setting and the meter enters the “STOP” interface.

E. Factory default settings:
 Trigger mode: Manual
 Smooth: 50HZ
 Standard Selection: LS-STD (Enterprise standard)
2. ON/OFF
 In POWER OFF state, short press “POWER” button to power on the meter. Information such as
calibration date, production date, version number, serial number will be showed on the meter after
powering on and enter into the last measurement interface -STOP Interface. In the STOP interface,
long press the “POWER “button to power off the meter.
 In the STOP interface, the meter will power off without any operation in 3 minutes.
 In the state of “READY”, the longest waiting time is 50 minutes .If the measurement cannot be
triggered after 50 minutes, the meter will shut down automatically.
3. Measurement
In the measurement mode, three operation states exist:
READY: In the auto trigger mode, this means the meter is waiting for triggering to begin a measurement.
RUN: The meter is in the process of measurement.
STOP: The data measurement is over.
In measurement interface:
M: Manual Measurement
A: Automatic Measurement
1) Manual Measurement：Short press the "POWER" key, Press "ENTER" to confirm the new
measurement and clear last measured data(show-----)and enters into the measurement state after 1

second(RUN state).Short press the “POWER” key or when the measurement time reaches 32
minutes, the measurement ends and enters into the STOP interface.
2) Automatic measurement：Press the button to start the new measurement then enter into the
“READY” state and clear last measured data ,（show"-----"and flash）,When the power value is greater
than the set value of trigger power, the trigger condition is satisfied then enter into the measurement
state (RUN state) .If the recording time reaches 40 minutes or the power value is less than the set
value of trigger power, the measurement will be automatically ended and enters into the STOP
interface.
4. The last measurement data view
After power on, the meter enters into the STOP interface, which displays the real-time value, maximum
power, energy, measurement time and power curve measured last time.
In the STOP interface, short press the "ENTER" key to toggle between the measurement result and
power curve.
In the stop status, long press the "ENTER" key to clear the current test data.
5. Low Power Alarm
When the battery power is low, the battery symbol " " on the bottom right of the screen will flash,
indicating that the battery needs to be replaced.

VI. PC Software Instruction
In the STOP interface (other interfaces cannot be connected to the PC software ), plug in the USB cable,
open "UV Energy meter Vx.x" software then the meter can be connected to the computer for you to read
the data .The software has various functions,
Such as parameter configuration, data reading, UV irradiance curve, report printing and power data
saving to EXCEL.
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 connecting USB cable with computer directly (when the meter is connected
to the computer USB port for the first time, the computer needs to be restarted so as to load the driver
automatically). Currently, the software supports Windows operating system.

VII. Precautions
1. The meter sensor needs to be facing towards the UV light source.
2. When not in use, please turn off the meter
3. Avoid contact with corrosive materials and keep away from high humidity.
4. Please put it in the plastic case after power-off and keep properly.
5. The suggested calibrating period is one year, and our company has the standard light source and
provides calibration service. (The previous calibration time “Cal date: year/month/day” will be
displayed on the boot screen.)
