How to Use Digital Multimeter:

If you are working on electronics you will need to know how to use a digital multimeter. The digital multimeter is one of the most useful tools for measuring, testing, and troubleshooting any type of electronic device. If you understand some of the basic settings you will know how to use your digital multimeter.

Instructions:

• Use your digital multimeter to test DC voltage by using the dial setting shown in the photo. Plug the red probe into the red voltage, Ohm, diode jack. Plug the black probe into the com jack. Hold the red probe on the positive side of the DC voltage source and hold the black probe to the negative side
• Use your digital multimeter to test DC minivolts by using the dial setting shown in the photo. Plug the red probe into the red voltage, Ohm, diode jack. Plug the black probe into the com jack. Hold the red probe on the positive side of the DC minivoltage source and hold the black probe to the negative side
• Test AC voltage with your digital multimeter by using the dial setting shown in the photo. Plug the red probe into the red voltage, Ohm, diode jack. Plug the black probe into the com jack. Hold the red probe on the positive side of the AC voltage source and hold the black probe to the negative side. Autoranging multimeters will automatically scale to the nearest voltage range. You can also press the range button to manually change the range to see the value in a different detail
• Test AC minivolts with your digital multimeter by using the dial setting shown in the photo. Plug the red probe into the red voltage, Ohm, diode jack. Plug the black probe into the com jack. Hold the red probe on the positive side of the AC minivoltage source and hold the black probe to the negative side
• Test resistors by setting the digital multimeter on the setting shown in the photo. Plug the red probe into the red voltage, Ohm, diode jack. Plug the black probe into the com jack. Hold the red probe on the positive side of the resistor in the circuit and hold the black probe to the negative side. Using this method a resistor can be tested in circuit or as a loose component
• Test continuity of a circuit by setting the dial to the setting shown in the photo. Plug the red probe into the red voltage, Ohm, diode jack. Plug the black probe into the com jack. Test circuit boards or wiring by holding one lead to one end of a trace or wire and the other lead to the other side of the lead or wire. If the multimeter beeps, then the wire or trace is good. If you do not have a circuit schematic, this is a great tool to use to map things out
• Test DC current (Amps) by setting the dial to the setting shown in the photo. Plug the red probe into the red A (Amps) jack. Plug the black probe into the com jack. Measure an in-circuit current by holding the red probe on the positive side of the circuit and holding the black probe to the negative side Do not test a current over the maximum amount shown on the jack or shown in your multimeter manual. You can switch to the smaller setting and jack if your current is low, but measure on this setting first
• Test AC current (Amps) by setting the dial to the setting shown in the photo. Plug the red probe into the red A (Amps) jack. Plug the black probe into the com jack. Measure an in-circuit current by holding the red probe on the positive side of the circuit and holding the black probe to the negative side Do not test a current over the maximum amount shown on the jack or shown in your multimeter manual. You can switch to the smaller setting and jack if your current is low, but measure on this setting first
• Use your digital multimeter to test a diode by using the dial setting shown in the photo. Plug the red probe into the red voltage, Ohm, diode jack. Plug the black probe into the com jack. Hold the red probe rear side of the forward bias and the black probe on the forward side. If you get a reading the diode is good. If the digital multimeter beeps, the diode is bad

Tips & Warnings:

• Do not set the multimeter on the resistor setting and touch the probes to a voltage source
• Do not test above 60VDC or 30VAC with your digital multimeter
• Be extremely careful around any voltage source AC or DC or when testing capacitors
• Never touch the probes to a voltage source with the probes plugged into the A and mA probe jacks

How to Read a Multimeter:

As the name implies, a multimeter is a tool with several different functions. It can measure voltage, resistance and amperage as well. It can be used to make sure that a circuit is working properly and diagnose bad solder joints, blown components and other problems. It is also a great tool for demonstrating how circuits work

• Set the multimeter dial to the unit you want to measure. Voltage is marked by a V, amperage by an A and resistance by an Ω, called an omega 
• Set the dial to the maximum value you want to measure. Usually, the values differ from each other by a factor of 10. For example, 10 ohms, 100 ohms and 1k ohms for resistance. The letter k stands for kilo meaning thousand. The letter m stands for milli, meaning thousandth. If you do not know what value to use, use the very highest to minimize the risk of damaging your multimeter 
• If you are measuring resistance, turn the circuit off and unplug it. Otherwise, power it on 
• Touch the probes to the two points you wish to measure the difference between. If you are measuring the resistance of a particular resistor, for example, put one on either side of the resistor. If you are measuring amperage, put the red lead on the positive side and the black one on the negative side of the circuit component you are measuring 
• Look at the value on the dial or digital display. If you are using a digital multimeter, it will tell you in exactly the right unit. For example, it will say 10 V if there is a 10 volt drop over the component. With analog multimeters, you read the dial as a value out of 10. If you had it set to 1 volt and the dial read a 5, it would mean 0.5 volts. If it were set to 100 millivolts and the dial read 5, however, it would mean 50 millivolts
• Change the setting if necessary. If the ohmeter registers a value that is less than 1/10th of the total, you should set it down one level lower. For example, if you have it set to 100 Ω and it reads below 10 Ω, you should set it to 10 Ω to get a more precise value
