Safety guidelines

When using any electrical test equipment it is advised that you refer to the user’s manual for proper working operating procedures and safety precautions in order to avoid potential safety hazards.

What is the difference between an analogue and a digital multimeter?

The main difference is the display. A digital multimeter will show the results as numbers on a screen (usually a LED or LCD screen) whereas the analogue version has a needle to show the value.

Warning

When using test leads or probes, keep your fingers behind the finger guards. Remove test lead from the meter before opening the battery door or meter case.
