The meter Features durable, convenient and accurate (but cannot be calibrated), has an LCD display Very nice color screen where it clearly shows electrical values, allows to simultaneously measure and display AC voltage, AC current, active power and electrical energy. Features: Large display Color LCD: voltage, current, active power and electric quantity values can be displayed in bright colors meanwhile. All the data will be clear at a glance. Automatic storage data: When the power is cut off, the device will automatically save the current power value, and read the value and continue accumulating when the meter is electrified again. Current transformer: Supplied with CT rated 0-100A, the meter allows easy and good measurement of current consumption, apart from the electronic device itself. Just make the wire move through the hole of the transformer. Reset function: Hold press the compensation button on the front panel of the device for 5 seconds, and the accumulated counter value will be cleared. Convenient to use Convenient multimeter: fast meter with measurement speed of 2 times/s the AC voltage measurement range 80-300V, current measurement range of 0-100A, the range of active power from 0-30000W, electrical energy range from 0-9999999kWh. Easy to install in your home, help you control voltage and current for electrical safety.
