The operation of a DMM, digital multimeter, itself is normally very straightforward. There may be additional connections for temperature probes or for transistor tests where three connections are needed, etc
The third is typically for current measurements, and there may even be one for low current ranges. another is typically for measuring voltage and resistance. One is a common connection to which the black probe is normally taken. There are normally three or possibly four connections. Years ago, these connectors were usually normal banana type plugs, but with safety more prominent these days, similar connectors, but with more protection against accidental touching of the conductive surfaces. There will also be the connections for the probes. This may include an off position, although some meters include a separate on / off switch. There will also be a main switch to select the measurement type: amps, volts, ohms, and any other types of measurement that need to be made. Normally towards the top of the main front panel is a screen which gives the readings and possibly a few other indications.

When looking at how to use a digital multimeter, DMM, it is worth understanding the main controls. Typical low cost digital multimeter How to use a digital multimeter However separate sections are given below with instructions on how to use a digital multimeter and how to use an analogue multimeter. Although basic operational multimeter instruction may be given when the test meter is bought, details of how to use the multimeter to test circuits and gain the maximum use from them are not always available.Īlthough there are major differences between the internal circuits within analogue and digital multimeters, the way in which they are used is comparatively similar. Multimeters are very cheap to buy and are one of the most commonly used pieces of electronics test equipment. Test meter basics Analogue multimeter How does an analogue multimeter work DMM digital multimeter How a DMM works DMM accuracy & resolution How to buy best digital multimeter How to use a multimeter Voltage measurement Current measurements Resistance measurements Diode & transistor test Fault finding transistor circuits How to use a Multimeter: digital & analog Using a multimeter, either analog or digital DMM is normally easy although a few useful instructions can assist in getting started as well as hints and tips can help.
