The digital multimeters are probably the most popular instruments for gauging different measurement units today. As the name indicates they can be used for multipurpose applications like measuring current in ampere, resistance in ohm and voltage in volt. However, there are different methods of doing the same. Here are simple guidelines for you to make optimal use of your digital multimeters.
How to use digital multimeters to test voltage?
The method involved in testing voltage with digital multimeters is different from that of testing current. The first step involved in the same is to first determine whether the test is for AC or DC voltage. This is very important as it has a great impact on the dial setting. Te next step is to determine the appropriate range, set the range slightly higher than the expected result for accuracy. And yes always ensure to consult a manual before connecting test leads to the circuit.
How to use digital multimeters to test current?
For testing current, the digital multimeters should be used along with a clamp meter or clamp meter adapter. Then install the head of the meter around a conductor and once it is closed you can take the measurement. The current clamp adapter makes taking measurements easy as it has the capability to convert the results into voltage. But before that all you have to do is set the function as if conducting an AC voltage test and set the range to millivolts. And lo, you get the accurate and precise results digitally. This is similar to digital pressure gauge varieties that are available in the market today.
How to use digital multimeters to test resistance?
For using digital multimeters to check resistance, the dial has to be set thus, the leads have to be connected and you can get the results accordingly. One word of caution thought- it is always advisable to turn the power off in the object being tested. This is to avoid impending technical damage in the multimeter and to do away with inaccurate results.
Make optimal use of digital multimeters by going through the user manual carefully and you would become a pro in no time. Just like infrared thermometers, these multimeters are best purchased online to get the best deals.
