Description

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. Reset energy function.
5. Store data when power off.
6. STN whole viewing angleLCD (display voltage, current, active power/energy at the same time)
7. Backlight function.
B. Appearance and Key function
I. Display Interface
The large-screen STN whole viewing angle LCD can display voltage, current, power, energy at the same time.(note: power and energy display can be switched by the key.)
II.Display format

1.Power: test range: 0~22kW
within 1KW, the display format is 0.0~999.9W;
1KW and above, the display format is 1000~9999W;
10kw and above, the display format is 10.0~22.0kW
2.Energy: test range: 0~9999kWh
Within 10KWh, the display format is 0~9999Wh;
10kWh and above, the display format is 10~9999kWh;
Over 9999kwh will return 0
3. Voltage: test range: 80~260V
Display format: 80~260V
4. Current: test range: 0~100A
Display format: 0.00~99.99A
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 at least3 seconds until the number in energy display area flash, then release the key.
Step2: If short press the key again, then the energy value is cleared and exit the reset state.If short press the key again, then the energy value will not be cleared and will exit the reset state. If there is no operation on the key within 10 seconds, the energy value will not be cleared and will exit the reset state.
3. Set power alarm threshold
Step1: Long press the key at least 3 seconds until the number in power display area flash,then release the key
Step2: Powerarea display the current power alarm value and the last digit begin to flash, then you can short press the key to plus 1, short press the key can switch the digit which you want to set. The threshold can’t be over 25kw( note: the default value is 25kw)



Step3: After finish the setting, long press the key over 3 seconds or there is no operation over 10 seconds, it will store data automatically and exit the set state.
4. Power/Energy switch
You can short press the key to switch display the power/ energy, the display state will be store when power off.
