CAT III / 600A: Measure CAT III 600V AC / DC current up to 600A without disconnecting the cable. Opening area for clamp meter 31 mm. ZERO function for track current. Perfectly suited for machine maintenance, in electrical cabinets and also for measuring high currents in vehicle and truck electrical systems. With the extended voltage measuring range up to 600 V and True RMS measurement (True RMS), you can also perform professional tasks reliably and safely. Multimeter functions: the digital multimeter measures voltage, frequency, capacitance, continuity, resistance, temperature with automatic range selection. The Non-Contact Voltage (NCV) tester allows 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: Safety standard IEC 61010-1, CAT III 600V. Double insulation.
