What is the infinity reading on a digital multimeter?

Continuity testing determines if an open, shorted or closed circuit exists in an appliance, electrical or electronic device and is a common use for multimeters. On a digital multimeter, infinity reads “0.L.” On a VOM, “zero” means a closed circuit has been detected.

Correspondingly, what does a reading of 0 ohms mean?

A single ohm (1 Ω) is actually a very small amount of resistance. Thus, a 1,000-ohm resistance is written as 1 kΩ, and a 1,000,000-ohm resistance is written as 1 MΩ. For the purposes of most electronic circuits, you can assume that the resistance value of ordinary wire is zero ohms (0 Ω).
