The DUSPOL analog 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) by means of high contrast light emitting diodes (LED"s) and by means of a solenoid operated voltage indicator. The voltage is indicated in the steps of 12, 24, 50, 120, 230, 400, 500 and 750 V. You can also perform polarity tests with direct voltage (DC) and single pole phase tests with...
