Electrical Tester, CAT III 1000V

For insulation resistance up to 4000 MΩ / CAT III 1000V /Easy handling Single or continuous measurement /Max/Min-value function. The insulation tester detects with auxiliary voltages of 125V, 250V, 500V. For new plants (dry rooms): 1000 ohms x volts of operating voltage (eg at 230 volts> 230 kOhms) For new installations (wet rooms, outdoors): 500 ohms x volts of operating voltage. Earthed devices: 1000 ohms x volts of operating voltage. Protected devices: 2 MOhm. Power tools: 2 MOhm. Protective extra-low voltage: 250 kOhm. Electrical measuring devices: 5 MOhm. Common test voltage values ​​are 100 volts for low voltage and telecommunication systems, 500 volts for building installation and home appliances, 1000 volts for low voltage motors and transformers. Large measuring range. 4 different test voltages up to 1 kV. Auto power-off function. Safety: EN 61010-1, CAT III 1000V, Dual display with backlight.
