Are you in the market for an instrument that measures Voltage, Current and Resistance? Than a Multimeter is the instrument of choice. There are a variety of multimeters in use today that serve a variety of purposes. They are often used in a laboratory, in the field or home use and they are manufactured in 2 designs.

Analog and Digital Multimeters (DMM) both serve the same purpose of measuring voltage, resistance, Current. Though Analog is considered the older model, it sometimes is the preferred choice amongst Engineers and Technicians because they are the most sensitive and can detect the smallest fluctuations. Analog meters are constantly performing measurements while DMM’s take a sample of the measurement at a particular time.

Multimeters are offered in a variety of designs and models, each of which comes with different price ranges. If you are unsure which model and price range would be best for you, the question to ask is what type of equipment are you working, with and how critical and accurate do the measurements have to be?

Multimeters are made up of amplifiers and resistors and over a period of time these components can wear. When this occurs, they will not be as accurate and will either require calibration or replacement. With high end models, quality components that make up the instrument allow you to recalibrate the multimeter , while lesser models usually require replacement.
