The small button on the front panel serves to turn on the LCD backlight, reset the kWh meter and set the alarm for a power level threshold detection.

Comes with one LCD panel and one 100A current transformer

Features

• Electrical parameter measurement function (voltage, current, active power, energy, frequency, power factor)
• Overload alarm function (over power alarm threshold, backlight and power flashing to alarm)
• Power alarm threshold preset function (can set power alarm threshold)
• The energy can be reset use the key
• Store data when power off
• Large-screen LCD 
• Backlight function
• Key Function

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.

Reset energy

• Step1: Long press the key for 5 seconds until the energy value flash, then release the key.
• Step2: Short press the key again, then the energy value is cleared and exit the reset flashing state.
• Step3: If there is no operation on the key within 5 seconds, it means the energy value is not cleared and will exit the reset state.

Set power alarm threshold
