Digital MULTIMETER -AC/DC

A digital multimeter or DMM is one of the most widely used pieces of test equipment today - they are almost invaluable in any electronics laboratory, for the home, hobbyist and professional electronics engineer.The cost of digital multimeters varies considerably. Some of these test instruments can be bought very cheaply and provide very good service and they are surprisingly accurate - far more accurate than is needed for most measurements, but top range multimeters are also available with very high specifications for use in the most demanding applications.Originally analogue multimeters were used, but these are only rarely used these days as digital technology has made digital multimeters cheaper, far more accurate and capable of providing many more capabilities beyond just measuring current, voltage and resistance.3 1/2 digits lcd with a max.
