Main parameters: AC \/ DC voltage and current test, diode, resistance, capacitance, frequency, phase conductor identification, duty cycle, temperature, true RMS, acoustic continuity test and live line with 10 range automatic, 6000 count display, 3.0 inch large LCD backlight, CAT III 1000V, CAT IV 600V, 2-in-1 manual automatic measurement. 2-in-1 manual and automatic range Our multimeter offers manual range selection and automatic. Auto-range means that you only need to select the measurement type, as the device can determine the measurement range itself. The auto range function is especially useful when you cannot judge the measuring range expected Large illuminated display and overload protection With the 3 inch illuminated display, you can easily read the value in low light condition. \u0026 nbsp; The digital multimeter automatically turns off after 15 minutes of inactivity, ceramic fuse and thermistor protection circuit ensure high level of safety during multimeter work Function features: fast measurement, strong anti-interference ability, high precision, high sensitivity (super sensitive electric field detection), high resolution (1\/5999 = 0.017 \u0026 nbsp; ), short circuit protection, high voltage protection, overload protection (double fuse protection ceramic), low energy consumption (Automatic shutdown function) Wide application: Checking the electricity of the house (wiring, sockets, appliances, etc.) Checking the vehicle electronics (battery, alternator etc.) Verification circuits (electric models, radios, electronic components etc.) Use by amateurs (amateurs, DIY enthusiasts, etc.) Use by professional users (electricians, electronics engineers, etc.) Ambient temperature measurement - Step 1: Turn the range selector to the appropriate value \
