A. Function

1. Electrical parameter measurement function (voltage, current, active power, energy)

2. Overload alarm function (over power alarm threshold, backlight and power flashing to alarm).

3. Power alarm threshold preset function (can set power alarm threshold).

4. The reset function of energy key.

5. Store data when power off.

6. Large-screen LCD (display voltage, current, active power, energy at the same time)

7. Backlight function.

B. Appearance and Key function

I. Display Interface

Display interface is a large-screen LCD, it can display voltage, current, power, energy parameters at the same time.

II.Display format

1. Power: test range: 0~2kW(20A version) 0~5kW(50A version) 0~10kW(100A version)

Within 1kW, the display format is 0.0~999.9W;

Within 1kW~10kW, the display format is 1000~9999W;

10kW and above, the display format is 0.1~22.0kW.

 

2. Energy: test range: 0~9999kWh

Within 10KWh, the display format is 0~9999Wh;

10kWh and above, the display format is 10~9999kWh.

 

3. Voltage: test range: 6.5V~100V

Display format: 6.50~99.99V

 

4. Current: test range: 0~20A(20A version) 0~50A(50A version) 0~100A(100A version)

Display format: 0.00~20.00A(20A version)0.00~50.00A(50A version) 0.00~99.99A(100A version)

III. Key

1. Backlight control

Short press the key to turn on or off the backlight, the backlight has memory function, it can store the on or off state when power off.

 

2. Reset energy

Step1: Long press the key until the power display area display “CLr”, then release the key.

Step2: At this moment, the energy is flashing to prompt this is the energy reset state, if short press the key again, then the energy value is cleared and exit the reset flashing state.

Step 3: If there is no operation within 5 seconds, it means the energy value is not cleared and will exit the reset state.

 

3. Set power alarm threshold

Step1: Long press the key until the power display area display “SET”, then release the key.

Step2: After enter this state, the voltage area display the current high voltage alarm value, the current area display the current low voltage alarm value and the last digit begin to flash, then you can short press to plus 1, when there is no operation over 3 seconds, it will switch the digit position automatically, from the high voltage alarm value to the low voltage alarm value, there are total six digits, the range of the voltage alarm threshold is 6.5～99.9V;

Step3: After finish the setting, long press the key until the screen display “PASS” ,that means you set successfully and will exit the setting state automatically.

 

C. Precautions

1. This module is suitable for indoor, please do not use outdoor.

2. Applied load should not exceed the rated power.

3. Wiring order can’t be wrong.
