AC Current Voltage Amperage Power Energy Panel Meter LCD Digital Display Ammeter Voltmeter Multimeter with Split Core Current Transformer CT AC 80-260V 100A Multi-Function Power Monitor

• 1. Digital Multimeter:This power energy meter can measure and display voltage current active power energy frequency and power factor at the same time.with split current transformer,more convenient to install .

• 2. Overload Alarm function:Backlight and power will flash simultaneously to give an alarm when exceeding the preset value.You can preset power limit by yourself.

• 3. Automatic Data Storage Function:The last test data is stored automatically when the power supply abruptly lose. Don't worry about data loss due to sudden power outages.

• 4. One-touch Control:The button can be used to control the backlight,reset energy, preset power alarm limit.

• 5. LCD Display:Large-screen LCD with all sight 180° view,The blue backlight can be turned on/off manually. PZEM-022 requires an external power supply to light up the screen.

A.Main Function 1. Electrical parameter measurement function (voltage, current, active power, energy, frequency, power factor) 2.
