Duspol is a series of voltage testing devices, which complies with the latest international standards.
By actuating the two membrane push-buttons, the measuring point can be loaded with a testing current in order to suppress irritating inductive and capacitive voltages.
Due to the load connection, the internal resistance of the voltage tester is reduced to such an extent, so that the measuring point is loaded with a maximum testing current of Is £200 mA. Thus it has the advantage that the voltage states of 'voltage present' or 'voltage not present' can be indicated absolutely definitely.
