It enables reliable earth resistance measurement without the need to disconnect the circuit under test or drive in auxiliary earth probes. It is therefore an indispensable tool for inspection technicians and electrical engineers working in urban areas, industrial premises or locations with concrete or tarmac surfaces.\u003cbr\/\u003e\u003cbr\/\u003e\u003cbr\/\u003eProduct specifications:\u003cbr\/\u003e\u003cbr\/\u003e- measurement without earth probes: thanks to the non-contact clamp method, you can easily measure the earth resistance of closed loops even in places where installing auxiliary probes is not feasible\u003cbr\/\u003e- Wide measurement range: the instrument reliably measures earth resistance from 0.01 ? to 1200 ? with a high resolution of 0.001 ?\u003cbr\/\u003e- Leakage current detection: in addition to earth resistance, it can measure AC leakage currents in the range of 1 mA to 30 A\u003cbr\/\u003e- Large jaw opening: the oval jaw opening (suitable for conductors and busbars up to 44 mm in diameter; jaw dimensions 65 × 30 mm) allows for comfortable clamping of even larger flat bars or down conductors with protective profiles\u003cbr\/\u003e- 4-digit LCD display\u003cbr\/\u003e- Internal memory and data transfer: allows storage of up to 500 sets of measured data, which can then be recalled on the display or transferred wirelessly via Bluetooth\u003cbr\/\u003e- Audible and visual alarm: easy setting of limit values – the meter immediately alerts you with an audible and visual signal if the permitted resistance or current limits are exceeded\u003cbr\/\u003e- Self-calibration on switch-on\u003cbr\/\u003e- Data storage: 500 sets\u003cbr\/\u003e- Enhanced durability and shielding: Double insulation and an integrated interference detection system effectively block electromagnetic interference from the surrounding environment\u003cbr\/\u003e- CE certification:  IEC 61010-1; IEC 61010-2-032; IEC 61326\u003cbr\/\u003e\u003cbr\/\u003e\u003cbr\/\u003eTechnical specifications:\u003cbr\/\u003e\u003cbr\/\u003e- Functions: Data Hold, Data Recall, automatic switch-off (after approx. 10 minutes of inactivity), low battery indicator, automatic calibration on switch-on\u003cbr\/\u003e\u003cbr\/\u003e- Earth resistance measurement: 0.01 ? to 1200 ?
