Multimeter maintenance and care

Storage

The fragile electronics within multimeters are protected by a hard casing, which means they can usually be stored in a toolbox. 

For devices with exposed metal probes, it is beneficial to cover them when not in use to avoid dirt accessing them and causing damage. Often the devices are provided with caps for the probes; if they are not, use something non-conductive to cover them (plastic or cloth).

Take a little extra care with the cables and try not to get them too tangled. 

Cleaning

Multimeters do not require any deep cleaning – just wipe them down with a damp (not wet) cloth, every now and again.

It may be helpful to ensure any probes or screens are kept clean, again using a cloth, to ensure you get accurate results. There are specialised cleaning wipes available for cleaning these. 

Maintenance

Ensure your devices are fully functioning before each use. Change batteries and fuses when necessary and consider removing the batteries if the mwter will not be used for an extended period of time.
