Frequently asked questions
Can it measure AC voltage?
The listing mentions AC current, DC voltage and DC current, but does not list AC voltage measurement. Check the manual before using it on AC voltage.
How do I use the diode test?
Set the dial to the diode symbol, place the red probe on the anode and the black probe on the cathode. A forward-biased diode shows a voltage drop, while a reversed reading shows overload.
