Gossen Metrawatt Installation tester NIN/NIV, 500MOhm, ±5 %, IP40

Large measuring range for TN/TT and IT systems from 65...550 V and 15.4...420 Hz. Cat III/600 V, CAT IV/300 V. Diagnostic functions for fault location. Fast loop and system impedance measurement without tripping the RCD. Insulation resistance with nominal voltages and rising test voltage, standing-surface insulation measurement. Low resistance measurements. Earth resistance measurements with probes, current clamp and flexible current sensor (selective earth resistance). Measuring of current, leakage current and equalising currents with optional current clamp. Testing of Residual Current Protective Devices (RCDs) with rising residual current, testing of selective and special RCD's. One-Hand handling; remote control in test probe. High precision measurements with 4-wire-systems (no zero compensation and no zero adapter needed). USB-interface and memory for building structure and measuring data, RS232 for barcode- or RFID scanner. Incl. software ETC for creation of individual building structures at the PC and...
