Use the switch on other sections only if you have made the functionality of these sections clear to yourself first (see the manual), otherwise the tester may become unusable.
NB: DC always stands for measuring batteries and accumulators (direct current ), ACV always stands for household current measurement (alternating current). 1.5V the location of the “+” terminal is always on the side of the red wire of the tester ( if the reading is with a minus sign, then exchange the measuring heads).īy turning the ACV 750 switch on, you can analogically measure the presence and polarity of household current (220V) – thus finding errors when “the current is lost”. By turning the switch to DCV 20, it shows the level of batteries and batteries and the location of the “+” terminal (for example, an AAA battery or battery is “full” when the tester reading is approx.
