The Duspol Digital is a voltage tester which has been tested and approved according to the new international standard for voltage testers.

The device indicates direct and alternating voltages (DC and AC) via an illuminated 3 digit liquid crystal display. The display illumination is activated automatically making the backlight turn on without any user input as soon as the conditions merit it.

The voltage is indicated continuously within a range from 1.5 V to 690 V and the value can be stored by means of the data hold function. You can also perform polarity tests with direct voltage (DC) and single pole phase tests with alternating voltage (AC). The Duspol Digital LC is also equipped with a special function to test the phase sequence of three phase mains, showing a right or left phase rotation on the digital display.

A very bright light-emitting diode (LED) is intended to illuminate the measuring point very precisely in case of unfavourable light conditions.

The load connection occurs via the two membrane push buttons, thus the measuring point is loaded with a maximum testing current of Is < 200 mA in order to suppress inductive and capacitive voltages.

By actuating the two membrane buttons, a vibrating motor is activated. The vibrating power of this motor increases proportionally to the applied voltage, hence the vibrating power indicates the level of the applied testing voltage. The energy supply is provided by two 1.5 V micro batteries, and the dust and splash proof case complies with protection class IP64, therefore making this device suitable for use in harsher environments. Being CAT IV gives it the highest safety rating.
