Basic Multimeter Tests

A digital multimeter might appear a bit intimidating at first sight, especially some of the some of the more advanced ones like Fluke multimeters, but once you get to know the display you will have a better understanding of the digital multimeter basics. There are two types of multimeters digital and analog. Digital multimeters are used more often nowadays as compared to the analog multimeters. Digital multimeters feature a digital display, where measurement and readings are in exact numerical values. This display also has the tendency to alert you if any pertinent symbols and warnings occur.

How To Test Current Using A Digital Multimeter:

Current can be tested with the help of multimeter in many ways but the most convenient and easiest method is with a clamp meter. The main benefit of testing current with the help of a clamp meter or a standard digital multimeter with a clamp head accessory is that the measurement readings can be taken without having to open the circuit. If you want to test current then first check whether you are testing AC current or DC current and then fix the dial to the suitable function, also set a suitable range on the dial.

Measuring Current Is One Of The Most Basic Tests You Can Perform With Your Multimeter

How To Test Resistance Using A Digital Multimeter:

You need to turn off the power in the circuit that you’re testing at first otherwise you won’t be able get the most accurate measurement reading. Ensure that all power is off and the dial is set to the resistance mode. You should also choose the suitable range on the dial. Now plug in the test leads, connect them to the particular component that is under test and take a reading. You have to make sure that there is a good contact between the circuit and test leads you’re testing. Any kind of dust or dirt can increase resistance readings significantly so make sure there is none present.

How To Measure Continuity Using A Digital Multimeter:

The circuits need to be complete and continuous so that the current may flow perfectly. Wire connectors, fuses, switches and conductors require good continuity. Good fuses and closed switches have fair continuity whereas the blown fuses and open switches tend to have no continuity whatsoever. You can conduct a basic continuity test to verify that the test leads are perfect before using the digital multimeters. The continuity test on the digital multimeters is pretty simple all you need to do is to set the dial to a continuity function and plug in the lead after ensuring that the power is turned off. Now try to make a contact with the component under test by using leads. The digital multimeter tends to beep if good continuity exists.

How To Measure Capacitance Using A Digital Multimeter:

If you want to test capacitance first set the dial on the digital multimeter to the capacitance function and plugin the leads. Connect the test leads to the capacitor terminals after making sure that the capacitor has been discharged and then take a reading. Now if the measurement reading is somewhat similar to the rating that is listed on the capacitor then the capacitor is considered to be good.
