3 Useful Multimeter Functions

While your choice of multimeter primarily depends on the meter's test capabilities, other factors can influence your decision. Multimeters come in different shapes and sizes; some have more features than others.

Before you make a final choice, it's worth looking at common features to see if you would use them. Which options are good to have?

1. An Autoranging Function

When you use a standard multimeter, you typically have to know the range that you're measuring. Each component typically has a different range that covers its particular value. Sometimes, you'll know the range, and sometimes you won't. If you don't, you may need to work it out or try each range function on the meter until you get a reading. This is time-consuming.

If you buy a multimeter with an autoranging function, then the meter does this for you automatically. For example, all you need to do is to set the meter to the right component and it gives you an automatic reading.

2. A Data Hold Reading

If you have a lot of readings to take and you need to make a record of them, then there may be times when you have to repeat readings unnecessarily. For example, you may use the meter and memorise its reading. Then, you have to put it down, find your pen and the recording form and fill it in.

It's easy to forget the reading if this takes too much time. If you're distracted, you might transpose figures and write down the wrong reading. Get to this stage, and you may have to start over.

it helps to choose a multimeter with a data hold function. This freezes the screen once it has a reading. This gives you time to get sorted. You can also double-check the reading before you record it.

3. An Auto Power-Down Feature

The batteries in your multimeter should keep it going for long periods. However, this meter does suck up power. So, if you forget to turn it off after using it, it'll deplete the batteries. Next time you pick up the meter, it might be dead. You'll spend more on battery replacements than you need to.

So, it's a good idea to look at multimeters that automatically power themselves down. If you don't use the meter for a set of period of time, it basically switches itself off so your batteries will last longer.
