The Electrical Tester has a measuring range of 0… 1000 A AC/DC. The current is measured inductively using the clamp on the measuring device. Live supply lines with a diameter of up to 32 mm (1.2") can be connected to the Electrical Tester. With the optional Rogowski coil, the measuring range of the Electrical Tester can be extended to up to 3000 A AC. The Electrical Tester has sub-functions for current measurement. The inrush current can be measured with the Electrical Tester. This is a particularly important function, as motors such as those installed in ventilation systems or hall lighting require a particularly high current when switched on.

In addition to current measurement, the Electrical Tester can also measure voltages from 0… 1000 V AC/DC, resistances, frequencies and capacitances. The functions can be set using the rotary selector switch on the Electrical Tester. With the NCV function, the Electrical Tester can be used to determine the absence of voltage without contact. As soon as a voltage of 150 V AC is applied, this is indicated by an additional red LED. This function is active for every measuring function selected using the rotary selector switch. An LED lamp is integrated in the Electrical Tester for optimal illumination of the measuring point.

The Electrical Tester can be connected to an Android or iOS device via the Bluetooth interface. With the free app for the Electrical Tester, the measured values ​​can be displayed, saved and further processed. The Electrical Tester thus covers a wide range of measuring tasks due to the multitude of functions.
