Today’s cars and machines are composed of electrical equipment that need regular maintenance to make sure nothing would go wrong. One of the usual ways of troubleshooting all the car’s circuits is by using the best digital multimeters.

A digital multimeter is a device for measuring the voltage, current, resistance, and electrical continuity of circuit components. Through this tool, you can calculate and view the ohms, volts, and amps present in the circuits.

Other functions a multimeter serves are capacitance measurement, diode test, temperature, frequency, and transistor current gain.

Important Parts of the Multimeter​

Working with a digital multimeter means knowing all of its parts. Handling a multimeter requires familiarity since it’s no ordinary measuring device. Here are the basic parts of your digital multimeter:

1. Dial: This is the arc-shaped scale seen through a window where you can identify the ranges of the circuits and the readings of your tests.

2. Selector switch or knob: This is the function button which allows you to switch to volts, amps, ohms, and even the scale of the meter.

3. Lead openings: These are two sockets, COM or Common, and V or O, standing for Volts or Ohms respectively.

4. Test leads: These are black and red test leads used to connect to the device you are measuring.

5. Battery and fuse compartment: Found at the back of the device, this is where your power source comes from when you conduct testing.

6. Zero adjustment knob: This is a small knob beside the dial that is only for adjusting the resistance or Ohms range.

Testing Open Circuits

An open circuit is the simplest and easiest to troubleshoot. It just involves isolating the circuit from the power and the ground, and then connect the self-powered test light to the ground side of the circuit.

Afterwards, you can start probing and then observe whether the light is out throughout the whole period, or if it is switched on. If it remains off, then the open is situated in the middle of the circuit and the probe.

On the other hand, if it is on, then the open is in between the probe and the end of the circuit.

Testing Short Circuits​

To prepare for short circuits, you must first isolate the circuit from the electricity source and the ground. Next, you need to connect the self-powered test light to a safe ground and then check any easy-to-reach point in the circuit.

Once you see a light turn on, it signals that there is a short somewhere in the circuit. To set apart the short, probe another test point at the furthermost part of the circuit. Keep in mind that the light should still be on and that’s when you can continue opening switches or removing parts.

Once the light goes out, it means that the short is now located between the last two circuit parts that were turned on.

Checking Working Diodes​

After familiarizing yourself with the short and open circuits, you can now determine if your diodes, one-way current valve, are working properly. First, disconnect the diodes from any power source or tool with voltage because this will affect the meter’s reading.

Then connect a probe to the device you want to assess and refer to the meter. After this, use the other probe and take note of the second reading. If one of the readings are within the range of the dial, then it means that the diode is working.

On the other hand, if the first and second readings are out of range, then it signals a flaw or problem within your device.

Measuring Voltage​

To measure the voltage, you should first turn off the power source of the circuits or the wiring which have different voltages. With your multimeter are two probe leads colored black and red, which will be inserted in the COM socket and the V-labelled socket respectively.

Afterwards, turn the dial of the meter range to 20 volts because this will give you the most number of decimal places in the display. Then, you can connect your multimeter in parallel to a circuit to calculate the voltage.

Now you can touch your black probe lead at the first point of the wiring and right after, turn on the power source. Following this, touch your red probe at a second point of test with an adequate distance from the black touch point. Consequently, your multimeter will display the voltage reading.

Measuring Current​

Similar to voltage measurement, you have to turn off the power of the circuit being measured and your two probe leads will be connected into different sockets. The black probe will be plugged into the COM socket and the red one will be attached to the mA socket.

Next, you connect the multimeter to this series and set the dial to the range of 10 volts. Following this, you turn on the power once again and wait for the display to show the current measurement.
