The Eclipse MT-3209 3-5/6 True-RMS Digital Clamp-On Meter measures ACA, DCA, ACV, DCV, frequency, resistance, capacitance, and temperature. It enables non-contact voltage detection with signal level on the LCD display and LED indication. It has V.F.C. technology for variable frequency current to filter interferential and to elevate measured accuracy and result. It features overload protection to prevent misuse and protect the user's safety. The big jaw has a 30mm fit for most cables. The LED flashlight enables assistive illumination in dark environments. The LCD display is also useful in dark areas. LoZ measurement enables users to release low resistant signal, filter inducted or false voltage, and get real voltage test results.
