Feature:1. MULTI FUNCTIONS: Digital clamp meter can accurately measure AC current, AC DC voltage, capacitance, frequency, duty cycle, resistance, diode, continuity and field line testing2. EFFECTIVE AND PRACTICAL: This clamp meter is a true utility for solving industrial and household electrical problems, with an LCD backlit screen and flashlight for easy use in dark work areas. Zeroing reduce data errors affected by the Earth magnetic field and help you get more accurate measurements3. NON CONTACT TEST: This clamp meter use non contact voltage testing with sound and light alarms. When the meter detects a weak AC signal, the green indicator lights up and the buzzer emit a slow, loud buzzer. When the instrument sense a strong AC electrical signal, the red indicator light will turn on, and the buzzer will make a short sound4. EASY TO READ: The digital clamp meter multimeter support data retention and automatically shut down after 15 minutes of inactivity, with low battery indicator and continuity buzzer5. LARGE CLAMP OPENING: The tongs can measure the current in the conductor without touching or interrupting the circuit. Compact size make AC clamp meter easy to operate in tight spacesSpecification:Item Type: Digital Clamp MeterMaterial: ABSBattery: 2 x AAA 7 batteries required(not included)DC Voltage: 400mV, 4V, 40V, 400V, 600VAC Voltage: 4V, 40V, 400V, 600VAC Current: 4A, 40A, 600AResistance: 400, 4K, 40 K, 400K, 4M, 40MCapacity: 40000nf, 40.00nf, 400.0nf, 4.000uf, 40.00uf, 400.0uf, 4.000mf, 40.00mfTemperature: -40 ~ 1000, -40 ~ 1832Diode: 1MV.Package List:1 x Digital Clamp Meter1 Pair of Black and Red Test Pen1 x Thermocouple1 x User Manual
