  • Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every consumer and industrial product, DMMs are a must for designing, testing, and troubleshooting. Here’s a look at the features and capabilities of DMMs, as well as how to use them safely. - Source: Internet
  • For auto range multimeter: In auto range meter just align the function selector to the Ohm sign “Ω” and get the reading immediately on the digital display. In the manual range, it is recommended to start from the lower range and go to the higher ranges unless you get the right results. The reason we start we a low range is because if your current value is bigger than the selected range you will get the reading of overload (OL) on the multimeter screen. This OL reading will vanish once you are in the right range. - Source: Internet
  • When safety is critical, you need the very best. A good digital multimeter is about more than just functionality. You need to know that it will work accurately every time. A good multimeter will alert you when there is power, and it will also help you to discern why a component or appliance is not working. - Source: Internet

    1. Select the A⎓ mA setting on your multimeter. Manual multimeter users should look for the correct range. If in doubt, start too high and work downwards. - Source: Internet
  • When using a digital multimeter, it’s important to keep a few safety precautions in mind. One thing to remember is to never operate the multimeter on live circuits. DC and AC currents can be dangerous, so make sure the multimeter is set to measure the correct voltage or current. Always read the multimeter’s manual before attempting to work with electricity. If the multimeter’s display shows a value that is greater than 30 volts, that’s not safe. - Source: Internet
  • To begin, make sure no current is running through the circuit or component you want to test. Switch it off, unplug it from the wall, and remove any batteries. Plug the black probe into the COM port on your multimeter. Plug the red probe into the VΩmA port. - Source: Internet
    1. If you’re still reading, here’s what you need to do. The ammeter must be placed in series with the circuit to measure current. So the wire feeding the circuit must be opened and the meter probes placed across the gap. For example, if you want to measure the current in a circuit with an outlet receptacle, you could - Source: Internet
  • The measurement of AC current by a digital multimeter is similar to that of DC current. Turn the rotary switch to the required level A, and the multimeter can be connected in series. When measuring current below 200mA, the red test lead should be inserted into the “mA” jack, and when measuring above 200mA, insert it into the “A” jack. The following figure shows the schematic diagram of measuring the working current of the lighting lamp. - Source: Internet
  • Turn the dial to Continuity Test mode. It will likely share a spot on the dial with one or more functions, usually resistance (Ω). With the test probes separated, the multimeter’s display may show OL and Ω. If required, press the continuity button. - Source: Internet
