CAT III/600A: Measure CAT III 600V AC/DC current up to 600A without disconnecting the cable. The opening area of the measuring clip is 31 mm. Tracking current zeroing function. Ideal for machine maintenance, control cabinets, and measuring high currents in vehicle and truck electrical systems. With the extended voltage measurement range up to 600 V and True RMS measurement, you can also perform professional tasks reliably and safely. Multimeter function: Digital multimeter measures voltage, frequency, capacitance, continuity, resistance, temperature, and automatically selects the range. A non-contact voltage tester (NCV) enables non-contact testing. LowZ and LPF: Low input impedance prevents false readings due to ghosting. Low-pass filter (LPF) for accurate measurement of frequency signals when measuring motors and transformers. Safety: IEC 61010-1, CAT III 600V safety standard. Double insulation. 7/24 service.
