The Craftsman multimeter is a useful tool for electricians and electronics technicians alike. It allows you to test the state of any electrical circuit. This includes AC/DC voltage, resistance and the amount of electrical current flowing through a circuit. It also allows you to troubleshoot specific problems within a circuit. Understanding how your multimeter works can be a challenge for anyone new to circuitry testing. Fortunately, the learning curve for the Craftsman 82025 is not steep, even for the newest user.
Step 1
Set the multimeter to the "AC" setting by pressing on the "AC/DC" switch in the upper-left corner of the multimeter. This also turns the multimeter on. Note the measurement settings on the multimeter's dial, which includes Ohms, Watts, Volts, Fahrenheit and Celsius. Set the dial to "Volts."

Step 2
Locate the two polarity jacks on the bottom of the multimeter labeled "+" and "-." Locate the leads used to test the physical circuits. These resemble soldering irons, but with needle-like tips. One of the leads is black (-), and the other lead is red (+). Connect the red lead to the positive jack and the black lead to the negative jack.
Step 3
Start by testing a nearby electrical outlet. Insert each lead probe into each hole in the electrical outlet. If there is power going to the outlet, the corresponding voltage will register on the multimeter's screen.
Step 4
Repeat this procedure to test both AC and DC circuits and with varying types of electrical measurements.
