Clamp meter. True-rms technology improves accuracy in noisy environments. Measures AC/DC voltage to 1000 V, AC/DC current to 600 A, plus resistance, frequency, capacitance, power and power factor, total harmonics distortion (THD) and individual harmonics from 1 to 25 includes inrush current measurement and phase rotation indication for 3-phase motors. Non-contact voltage detection enhances safety. Low pass filter enables measuring voltage and frequency on variable frequency drives. Continuity beeper quickly identifies shorts and opens. Large backlit digital display with analog bar graph presents the full picture. Minimum, maxiumum and smart data hold. Peak hold identifies spikes and transients. In-jaw flashlight automatically lights when jaws open to illuminate dark panels and junction boxes. Auto power off conserves battery life. Maximum jaw opening accommodates large conductors up to 1.45. Rubber overmold body absorbs shocks, drop proof to 4 ft CAT IV-rated AC/DC current clamp meter includes test leads, batteries (installed), deluxe carrying case and user's manual.
