Feature 1High Efficiency: The clamp meter can only measure AC current (no DC current), AC and DC voltages, resistance, capacitance, continuity, diodes and frequency (Hz), band, neutral line. A digital clamp meter is the perfect ammeter troubleshooting tool, you can accurately troubleshoot vehicle or internal electrical problems in a very short time and get the job done more efficiently. 2Double Opening Jaw: The maximum wire diameter that the clamp meter can measure without interrupting the circuit is 1.42inch. Double opening jaws to suit your operating habits. 3Non Contact: The clamp meter makes it easy to quickly determine the existence of voltage. A short press on the NCV button in any gear switches the NCV non contact AC voltage detection function. 4Stylish and Durable: The clamp meter can handle the demands of long hours of work, from the durable exterior to the extensive heavy duty features. Stylish and durable, which prevents any damage or scratches caused by accidental bumps or drops, ensuring the device is in fine condition when travelling or outdoors. 5Wide Application: This clamp meter is used to measure AC currents and is widely used in laboratories, factories and homes.Item Type: Clamp MeterMaterial: ABSBatteries: 2 x AAA batteries (not included)AC Voltage Range: 4V-600VDC Voltage range: 400mV-600VResistance Range: 400-40MAC Current range: 40A-400AFrequency Range: 10Hz-400kHz, 400kHz-4MHzCapacitance Range: 1nF-4uF, 4uF-400uF, 4mFTemperature Measurement Range: 0-750 (32-1382) .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 xClamp Meter1 x Black Test Pen1 x Red Test Pen1 x Instruction Manual1 x Storage Bag
