Operation

Parame ter setting
In OFF mode, long press the “POWER” button for 3s and enter the parameter setting mode:

• 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 mete r 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

• B. Trigger power: 0.1 5.0mW/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 e nters the smooth interface
  C. Smooth:
  50HZ/60HZ If the UV light source uses an 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 (s elect 50HZ for DC power supply).

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, serial number , and then enters the last measurement interface (STOP interface). As shown below: 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 with in 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; th is means the meter is measuring data.
• STOP: Measurement is over.
• In measurement interface:
• M:Manual measurement mode
• A:Auto measurement mode
  • 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) a fter 1s. The interface dynamically displays energy E, real time power value P, real time temperature value T, measurement time. Short press the “POWER” button or after 32 minutes, the measurement is over and enter the STOP interface. The interface displays the measurement result energy E, maximum power value P MAX , maximum temperature value T MAX and measurement time.
  • Automatic mode: After pressing the button to confirm the new measurement, the meter enter the READY state to clear the historical data and wa it 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). The interface dynamically displays energy E, real time power value P, real time temperature value T and measurement time. 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 in terface. The interface displays the measurement result energy E, maximum power value P MAX , maximum temperature value T MAX and measurement time. In the stop status, long press the “SELECT” key to clear the current test data.

Charging

This meter has a buil t in lithium rechargeable battery. Please charge it in time when the battery symbol on the screen is empty during use. After plugging in the charger, the energy bar in the battery symbol increases, indicating that it is charging. Charging can be done in th e following ways:

1. Use an USB data cable, plug it directly into the USB port of the computer.
2. Use the matching 5V switching power supply.
3. The mobile power supply for smart phones.

Measurement and Notes

1. The sensor must face the UV light source.
2. When not in use, please long press the “POWER” button turn off the meter.
3. Avoid contact with corrosive materials and keep away from high humidity.
4. Please put it in the specialized package after power off and keep properly.
5. The suggested calibrating period is one yea r 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.)
6. For the UV sensor is very sensitive to humidity, the storage environment i s very important. For a long time storage, please be sure to keep the meter in dry environment.
