Characteristics of Meter
- It is the real smart UV energy meter with a large LCD to display the temperature and irradiance curvedirectly.
- It is equipped with a USB port and the computer software can read the detailed record data, generating data curve and print out test reports.
- It is with a high precision fast response temperature sensor and can measure the real temperature in the curing machine dynamically.
- It is with a built-in heat resisting sheet, can resist high temperature and operate at 100°C for long time.
- The meter is with a built-in large memory and can record irradiance data up to 60,000 andtemperature data up to 3800.
- The stored data will not be lost when the power is off and the last test data will be displayed automatically when power is on; the test data can only be deleted manually.
- It is with high accuracy and has passed many tests of authoritative testing organizations and got certificates.
- It is with a built-in timer, and can record the UV curing time accurately.
Operation
- Parameter setting
In OFF mode, long press the “POWER” button and go to the setting mode: In the setting mode, “SELECT” 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: 0.5-5mW/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
D. Factory default settings
Trigger mode: Manual
Smooth: 50HZ
2. ON/OFF
-
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, 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. -
In the “STOP” interface, the meter will automatically power off in 3 minutes without any operation.
-
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.
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)
- 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 “POWER” button or after 32 minutes, the measurement is over and enter the STOP interface.
- 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.
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.
USB communication
This meter has the function of 32-minutes data recording.
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.
PC Software of Meter
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. 
Notes
- The meter sensor is at the back of meter
- When not in use, please turn off the meter
- Avoid contact with corrosive materials and keep away from high humidity.
- Please put it in the specialized package after power-off and keep properly.
- The suggested calibrating period is one year, and our company has the standard light source and provides calibration service. (The previous calibration time “Calibration: year/month/day” will be displayed on the boot screen.)
- For the UV sensor is very sensitive to humidity, the storage environment is very important. For a long time storage, please be sure to keep the meter in dry environment.
