High Voltage Probe is designed to measure the voltage of an AC/DC voltmeter from 100 volts to 15000 Volts (15 kV). As per the Principle of High Voltage Probe, Input of Probe is connected to the High Voltages Sources (Range= 1000Volts), where Multimeters cannot measure the voltage beyond 1000 Volts & output is connected to the Voltmeter.
