Whether you are looking to purchase a new multimeter or get more out of the one you already have, there are several important things you should know. This is especially true if you are dealing with a bench multimeter. Here are some of the most important things that you need to know.
Bench vs. Handheld Testers
The main types of multimeters are bench and handheld testers. Bench testers tend to provide higher accuracy, better resolution, sophisticated programming options, and advanced functions, so they tend to be more popular.
Digits
A common question about these devices concerns digits and half-digits since this is one of the first things you need to learn about multimeters. The easiest way to find out what a half digit means on your machine is to look at the chart on the front panel next to the machine’s model number. If this is worn down, you can check online tables.
Visualization
Think about how you want to see your measurements. There are several different ways multimeters can display data. A lot of people enjoy a traditional numeral display. However, some offer charts and histograms. Others will give you numerals and the option to transport the information to a spreadsheet on a computer and view it through a different graph or chart option. If your workspace is crowded, you could benefit from a multimeter that clearly displays the information, so it is easy to identify.
Auto Calibration
If you look at a datasheet produced by one of these devices, you will notice that it is most accurate immediately after being calibrated. Over time, the accuracy will worsen. When other factors, such as temperature changes, are added, you can have problems. For instance, your data can be skewed. Therefore, it is recommended that you consider a machine with auto-calibration or one that provides statistics for how your data will have been impacted over time.
By understanding this information, you can get the most out of your multimeter. If you are purchasing your first one, you will have a better idea of what to look for. Remember to look for these features to find and use your machine perfectly.
