Digital Multimeter
Introduction:
A multimeter or a multitester, also known as a volt/ohm meter or VOM, is an electronic
measuring instrument that combines several measurement functions in one unit. A
typical multimeter may include features such as the ability to measure voltage,
current and resistance. There are two categories of multimeters, analog multimeters
and digital multimeters
A multimeter can be a hand-held device useful for basic fault finding and field
service work or a bench instrument which can measure to a very high degree of accuracy.
They can be used to troubleshoot electrical problems in a wide array of industrial
and household devices such as batteries, motor controls, appliances, power supplies,
and wiring systems.
Modern multimeters are often digital due to their accuracy, durability and extra
features.
In a Digital Multimeter the signal under test is converted to a voltage and an amplifier
with an electronically controlled gain preconditions the signal.
A Digital Multimeter displays the quantity measured as a number, which prevents
parallax errors.
