The meter features durable, practical and accurate(but cannot be calibrated), has a very nice color display LCD where it clearly shows the electrical values, enables to simultaneously measure and display the AC voltage, AC current, active power and electric energy. Features: Large Color LCD Screen: Voltage, current, active power and electric quantity values can be displayed in bright color meanwhile. All data will be clear at a glance. Data Auto-Storage: When power is off, the meter will automatically save the current power value, and will read the value and continue to accumulate it when the meter is electrified again. Current Transformer: Comes with CT rated 0-100A, the meter enables to easily & well measure current consumption, outside the electronic device itself. Just make the wire go across the hole of the transformer. Reset Function: Hold press the clearing button on the front panel of the meter for 5 seconds, and the meter's accumulated value will be cleared. Convenient to use! Practical Multimeter: Meter with fast measuring speed of 2 times/s has voltage measuring range of AC 80-300V, current measuring range of 0-100A, active power range of 0-30000W, electric energy range of 0-9999999kWh. Easy to install it in your home, helping you monitor the voltage and current for electrical safety.
