Typical Applications
Ohmmeters are electrical instruments that measure electrical resistance of a circuit. There are various types of meters available with different sensitivity levels which include micro, mega and milliohm meters. These RS PRO meters are milliohm meters and can be used for measuring:

Resistance
Motor coils
Transformers
Printed circuit boards
Conductors
Light electricity
Welding point
