CAT III/600A: Measure CAT III 600V AC/DC current up to 600A without disconnecting the cable. Opening area for measuring clip 31 mm. ZERO function for track current. Perfectly suited for machine maintenance, in control 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 (True RMS) measurement, 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 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.
