Features 1、MULTI FUNCTIONS: Digital clamp meter can accurately measure AC current, AC DC voltage, capacitance, frequency, duty cycle, resistance, diode, continuity and field line testing 2、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 measurements 3、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 sound 4、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 buzzer 5、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 spaces Specification Item Type: Digital Clamp Meter Material: ABS Battery: 2 x AAA 7 batteries required(not included) DC Voltage: 400mV, 4V, 40V, 400V, 600V AC Voltage: 4V, 40V, 400V, 600V AC Current: 4A, 40A, 600A Resistance: 400Ω, 4KΩ, 40 KΩ, 400KΩ, 4MΩ, 40MΩ Capacity: 40000nf, 40.00nf, 400.0nf, 4.000uf, 40.00uf, 400.0uf, 4.000mf, 40.00mf Temperature: -40 ~ 1000℃, -40 ~ 1832℃ Diode: 1MV Package List 1 x Digital Clamp Meter 1 Pair of Black and Red Test Pen 1 x Thermocouple 1 x User Manual
