What does M mean on a multimeter?

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.

Is a house AC or DC?

Home and office outlets are almost always AC. This is because generating and transporting AC across long distances is relatively easy. At high voltages (over 110kV), less energy is lost in electrical power transmission.

How can I use an analog multimeter as an ammeter?

You can get a good example of the readings on resistance using your analog multimeter, as a resistance ammeter. build or use a circuit with a light sensor along your circuit. The readings are taken from the poles of your resister itself.

What should I know before using a multimeter?

The first thing to learn before using a multimeter is to understand current. There is two current used to run machine. That is AC and DC. The AC is for alternative current and DC is direct current. Alternative current periodically reverses direction and is mainly used in appliances in houses and anything you can plug into the wall.

What is the selection knob on a multimeter?

Most multimeters have a selection knob with an arrow at the front side to guide you when taking voltage or resistance measurements. The knob usually points to a number of voltage, current and resistance calibrations. 4.

Where do you plug the com probe into a multimeter?

Proceed with connecting the COM probe to the other side of the electrical components. You’ll get the precise voltage value on the display if you connected the probes correctly. Begin with plugging the red probe into the port on the right side of your multimeter.
