The EX350 from Extech Instruments is an 11 function true RMS multimeter + NCV. The EX350 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. 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, duty cycle, diode test, continuity. It also features a 4000 count LCD display, data hold, min-max, relative mode, capacitance zero, auto power off.
