600A AC/DC TRMS TightSight® Clamp Meter w/FlashlightThe IDEAL 61 757 TightSight Clamp Meter is a CAT IV 600 CAT III 1000 V rated auto ranging true root mean square (TRMS) digital clamp meter that measures up to 600 Amps AC and DC current via the clamp head. It measures up to 1000V AC and DC, Low Impedance AC Voltage (Lo Z) (to reduce the possibility of false readings due to ghost voltages) , frequency, resistance, continuity, capacitance, and diodes via test leads (included) and measures temperature (F
