5000 V Insulation Measuring Instrument, AnalogAnalog high-voltage insulation measuring instrument with the following voltages:100, 250, 500 and 1000 V (per EN 61 557 part 1) and 1500, 2000, 2500 and 5000 V.Features in detailTest Voltages to 5000 VThis instrument is suited for the non-destructive measurement of insulation resistance in electrical systems, at machines and transformers and in cables, as well as within the electrical equipment of, for example, locomotives, tram systems and ocean going vessels, with eight selectable test voltages up to 5 kV.Voltage Measurement to 2000 VWith the voltage measuring ranges, test objects can be checked for the absence of voltage in networks of up to 2 kV. This is important for insulation resistance measurement, because extraneous voltages distort measurement results.Discharge of Capacitive Devices Under TestCapacitive devices under test such as cables and coils, which might be discharged to test voltage, are discharged by the measuring instrument. The drop in voltage can be observed at the needle gauge.Measurements in accordance with EN 61557 part 1 and 2 (VDE 0413)Measuring current is equal to 1 mA at a test voltage of 100 V, 250 V, 500 V and 1000 V.Measurement Cables with Heavy-Duty InsulationThe measurement cables with heavy-duty insulation are permanently connected for safety and technical reasons. Possible danger caused by the unintentional removal of cables is thus avoided, for example when charging occurs due to capacitive test objects.Needle Gauge with LEDsThree LEDs arranged within the needle gauge make reading easier. The lamp lights up which is located next to the scale, which is assigned to the selected measuring range. During the measurement sequence, the green LED indicates whether or not the battery charge is sufficient for the measurement.
