Things You'll Need
9-volt battery
100-ohm resistor
A multimeter is a tool used in electronics to measure a spectrum of different values, ranging from volts to ohms (resistance). The difference between an analog multimeter and a digital multimeter is that measurements from a digital meter are shown on a digital display screen, while an analog meter has a printed display scale of different electronic values that must be read.
Simple Voltage Test
Step 1
Power up your multimeter. Make sure the positive and negative test leads are attached.

Step 2
Turn the multimeter to the voltage setting.
Step 3
Place the positive end of the meter to the positive post of the nine-volt battery and the negative to the negative post. The reading will fall on nine volts if the battery is good.

Simple Resistance Test
Step 1
Turn on your multimeter and make sure the leads are connected.
Step 2
Switch to the resistance setting, which is measured in ohms.
Step 3
Place the negative end of the meter to the 100-ohm resistor and place the positive end to the positive end of the resistor. If the resistor is good, the measurement will fall at approximately 100 ohms.
