What do the symbols on a multimeter mean? ›

Voltage (V), resistance (Ω), diode test (arrow plus symbol), capacitance (other symbol), temperature. Red test lead input for: Measurements for voltage, resistance, diode, capacitance, frequency, duty cycle and, if available, temperature.

Read the voltage on the multimeter's screen.

Once your probes are connected to the positive and negative leads, you'll get a reading on the multimeter telling you the voltage of what you're testing. Look at the digital screen to find the reading and take note of it if desired.

There are five commonly used symbols in Electrical – Switch, Wire, Contactor, Motor, Transformer. These symbols can be used in any electrical drawings. Switches are used for ON/OFF any control circuit. Contactors are used to ON/OFF any electrical equipment through electrical signals.

If you have a reading higher than 10 ohms, you have poor continuity. The resistance is higher than it should be and you need to replace the wire, fuse, outlet, battery, or device.

Precautions in Handling and Using a Meter

Do not drop any meter. Do not overload any meter. When in doubt, use a high range that you know will not be overloaded. You can always switch to a lower range if necessary.

Using one hand, connect the lead with the alligator clip to one of the circuit's terminals, then place the other lead in contact with another terminal to make the reading. No more than one hand should be holding a lead or touching vehicle ground at any time.

You have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if you've measuring a 12V battery, use the 20V setting.

Plug the red cable for your multimeter into the V/mA/CAP port and the black one into COM. 2. To enter continuity mode, turn the dial to the continuity symbol, which will resemble sound waves emerging from a little speaker, or a symbol for a musical note (♫).

Switch on the multimeter and turn the dial to the AC setting. AC stands for alternating current and this setting measures the volts that an outlet is putting out. Find the power switch on your multimeter and switch it on. Then, locate the dial on the front of the multimeter and turn it to the AC setting.

If your multimeter has a dedicated continuity setting, turn the selection knob to continuity. Verify the meter and probes are working by touching the tips of the probes together. The meter should beep if it's working properly.

What are the different V symbols on A multimeter? ›

One “V” symbol is for AC voltage. The other “V” symbol is for DC voltage. The AC voltage symbol will be a “V” with a “∿” over the V.

An analog multimeter uses a needle that moves along a scale to indicate the value of the measurement. A digital multimeter uses a numeric display to show the exact value of the measurement. Analog multimeters are cheaper, more durable, and more responsive than digital ones.

The ohm is represented by the Greek letter omega (Ω). Ohms are sometimes expressed in power-of-10 multiples to accommodate large quantities.

The selection knob allows the user to set the multimeter to read different things such as milliamps (mA) of current, voltage (V) and resistance (Ω). Two probes are plugged into two of the ports on the front of the unit. COM stands for common and is almost always connected to Ground or '-' of a circuit.
