The EX355 from Extech Instruments is a 12 function true RMS multimeter + NCV. The EX355 is a professional DMM loaded with advanced features and functions. In addition to standard DMM features, it offers a Low impedance (LoZ) mode, backlit LCD, non‐contact voltage detector that safely senses electrical sources, variable frequency voltage measurement and temperature. Low impedance (LoZ) mode eliminates false readings caused by ghost voltages. Low pass filter (LPF) attenuates high frequencies to reduce noise for accurate readings. True RMS provides accurate readings when measuring distorted or noisy waveforms. Built-in non-contact AC voltage detector with LED indicator quickly checks for the presence of AC voltage before testing. Functions include NCV, AC/DC voltage, AC/DC current, resistance, capacitance, frequency, type-K temperature, duty cycle, diode test, continuity. It also features a 6000 count LCD display, data hold, min-max, relative mode, capacitance zero, auto power off.
