standard.

V. Operation

1. Parameter 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

Shenzhen Linshang Technology Co., Ltd.

2020-10-26 Page 4 of 8

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 valuesetting interface; Select Manual, the meterenters 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: 0.1-5.0mW/cm²can 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: 50HZ/60HZ

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 (select 50HZ for DC power supply).

50HZ: 50HZ AC.

60HZ: 60HZ AC.

Short press the "POWER" button to confirm the setting and enter the “STOP” interface.

D. Standard Selection

Short press the “POWER” button to select the standard.

LS-STD (Enterprise standard ): The meter is calibrated according to Enterprise standard

JJG 879-2015 (Chinese national standard): The meter is calibrated according to Chinese national

standard.

Short press the “POWER” button to confirm the setting, the meter enters the “STOP” interface.

E. Factory default settings:

Trigger mode: Manual

Smooth: 50HZ

Standard Selection: LS-STD (Enterprise standard)

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, serial number, etc. 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 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 measuring data.

STOP: Measurement is over.

In measurement interface:

M: Manual measurement mode

A: Auto measurement mode

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 "-----"),

Shenzhen Linshang Technology Co., Ltd.

2020-10-26 Page 6 of 8

automatically enter the measurement interface (RUN state) after 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 andenter the STOP interface.

The interface displays the measurement result energy E, maximum power value PMAX, maximum

temperature value TMAX and measurement time.

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). 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 interface. The interface displays the

measurement result energy E, maximum power value PMAX, maximum temperature value TMAX and

measurement time.

In the stop status, long press the "SELECT" key to clear the current test data.

4. Charging

This meter has a built-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 the 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.

VI. 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 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.)

6. 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.

VII. Heat Shield

Equipped with heat shield to avoid damage to the screen caused by high-power UV lamps irradiating the

instrument at close range.
