A clamp multimeter is a versatile electrical testing instrument used to measure AC/DC current, voltage, resistance, continuity, frequency, capacitance, and diode testing without disconnecting the circuit. The clamp jaw measures current by clamping around a single conductor, making it a safe and efficient tool for electricians, maintenance engineers, and industrial technicians. Features Measures AC and DC current without breaking the circuit AC/DC voltage measurement Resistance and continuity testing with buzzer Diode and capacitance testing Frequency and duty cycle measurement LCD display with backlight Data Hold and Max Hold functions Auto-ranging and auto power-off Non-contact voltage (NCV) detection (available in select models) Compact, lightweight, and easy to operate Specifications Current Measurement: AC/DC up to 600A or 1000A (model dependent) Voltage Measurement: AC/DC up to 600V or 1000V Resistance: Up to 60 MΩ Capacitance: Up to 60 mF Frequency: Up to 10 MHz Display: 6000-count digital LCD with backlight Continuity: Audible buzzer Safety Rating: CAT III 600V / CAT IV 300V (varies by model) Power Supply: 2 × AAA or 9V battery Operating Temperature: 0°C to 40°C Applications Electrical maintenance Industrial automation Power distribution panels HVAC system servicing Solar and renewable energy installations Motor and pump troubleshooting Commercial and residential electrical inspections A clamp multimeter is an essential diagnostic tool that provides accurate electrical measurements while improving safety by allowing current measurements without direct contact with live conductors. It is widely used by electricians, maintenance professionals, and field service engineers for fast and reliable troubleshooting.
