This instrument is a 6000 counts hand-held automatic range True RMS digital clamp meter. The circuit design of the meter takes the large-scale integrated circuit ∑/△ analog-to-digital converter (ADC) as the core, and it has the full-range overload protection. It can be used to measure AC and DC voltage, low-pass filter V.F.C, low-impedance Low Z voltage, AC and DC current, resistance, diode, continuity test, capacitance, frequency, duty cycle, temperature and other parameters, at the same time, it has the data hold, relative value measurement, surge current measurement function, flashlight function, NCV function, Live line judgment, low voltage display and automatic shutdown function.
