Backlight control <br>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. <br>2. Reset energy <br>Step1: Long press the key for 5 seconds until the energy value flash, then release the key. <br>Step2: Short press the key again, then the energy value is cleared and exit the reset flashing state. <br>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. <br>3. Set power alarm threshold <br>Step1: Long press the key until the LCD screen display"SET CLr", then release the key to enter the setting state <br>Step2: Power window display the current power alarm value and the last digit begin to flash, then you can short press to plus 1, when there is no operating over 3 seconds, it will switch the digit position automatically, the setting method is as same as the above. <br>Step3: After finish the setting, long press the key over 5 seconds will store automatically and exit, the range of active power threshold is 0.0~2.5kW. <br> <br> <br>Note: <br>1. This module is suitable for indoor, please do not use outdoor. <br>2. Applied load should not exceed the rated power. <br>3. Wiring order can't be wrong.<br>1、Electrical parameter measurement function (voltage, current, active power, energy, frequency, power factor) <br>2、Overload alarm function (over power alarm threshold, backlight and power flashing to alarm). <br>3、Power alarm threshold preset function (can set power alarm threshold). <br>4、The energy can be reset use the key. <br>5、Store data when power off. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
