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.
