True-RMS Clamp MeterThis multimeter can accurately measure 1000 Amp AC/DC Current 1000V AC/DC Voltage Frequency Duty Cycle Resistance Capacitance Diode Continuity and Temperature. Easy to use for labs factories and households.Inrush Current MeterKnowing the value of inrush current can help you locate a startup problem quickly whether it's in the motor or in the starting circuit. The measuring time of the inrush current is about 100ms. When the current is greater than 10A the Inrush function works well. The inrush function is only available in AC current mode.NCV Detection & Flashlight/BacklightBuilt-in Non-Contact Voltage (NCV) Detector can easily and quickly determine whether there is a voltage. A convenient flashlight illuminates a dimly lit area; an upgraded screen with a backlight helps reading in direct sunlight easier and clearer.Advanced FunctionsThe Clamp Meter has Variable Frequency Drive Filtering (VFD) and low Input Impedance (LoZ) modes which can provide higher accuracy readings.
