A low ohm reading indicates that the element is good. Most pop-up toasters work in the same manner. % of people told us that this article helped them. While most multimeters can also measure alternating current (AC), its not really a good idea (especially if its live power), since AC can be dangerous if you end up making a mistake. Of course, it can read voltage . If the pointer deviates from zero, go ahead and use the turning mechanism to return it to zero so that it is adjusted for errors. With the free ends, make a connection on the first terminal with one of the probes ends and use the other to contact the remaining terminal. A reading between 12.4-12.7 volts means that the battery is in good shape. Make sure you set the multimeter to test volts at the proper range. In the case of screw terminals, loosen the screws with an appropriate screwdriver and remove the wires. Multimeters also measure resistance in ohms () and continuity.
