Features: Wide Measurement Range: can be used to measure AC/DC voltage, AC/DC current, capacitance, frequency, duty cycle, resistance, line continuity, diode, fire/zero line detection, temperature, NCV test, etc. Smart Measurement: it can automatically match DC current, AC voltage, resistance, continuity without changing functions. When measuring AC voltage, the frequency displayed at the same time. When measuring resistance, when the resistance is less than 50Ω, the buzzer will sound and the indicator will light up. HD Backlit Bright Screen Display: multifunctional large screen 2.98-inch digital display with backlight for clearly readout even in the dark environment. Measurement Data Retention: hold the display after you take the measurement, convenient for you to write down the measured data or enter it into a spreadsheet. More Features: true RMS, continuity buzzer, backlight/flashlight available, 15 minutes auto-off, AC/DC current 600mA Max, AC/DC voltage 600.0V Max (CAT.III) Compact Pocket Size: as small as a smart phone, convenient for carrying around, cover with a silicone sleeve for effectively protect the multimeter from damage.
