A multimeter measures voltmeters, ammeters and ohmmeters. These tools have become invaluable for anyone who has an interest in electronics. Today?s multimeters have undergone technological innovations that have made them easy to use by technicians of all skill levels.
Features to consider
Multimeters are a test tool that measures at least two electrical values, such as resistance, voltage or amperes. These standard diagnostic tools come in two main groups: analog and digital. Analog outputs are typically displayed through a moving pointer that indicates a range on a spectrum. A digital multimeter, by comparison, has a numeric display or other visual cues, such as a light, that present readings to the user.
Some multimeters come with an auto-range function. The auto-range function means your device is able to recognize the type of current you are testing. It also means that you do not need to pre-select a specific range. However, manual ranges allow you to select a specific range, better tailoring the device to your project.
Durability is also another factor worth considering. If the area you are testing requires the use of a ladder, a device that could not survive a fall is not advisable.
Other safety features, like internal blast shields, wide flanges, or isolated slots, are also worth thinking about before buying a new multimeter.
