One of the most common mistakes I hear techs make is confusing Zero ohms with infinite ohms. The fuse above is showing near zero Ohms which means a good electrical path with very little resistance.
If there is a perfect path it would have zero ohms (which isn’t actually possible unless you happen to be testing a superconductor).
If there is no path, the circuit has infinite ohms. This would be shown as Open or OL or something similar.
Often when I ask what ohm reading a tech is getting they will say “none”… None could easily mean zero or infinite so it’s important to clarify.
Zero ohms = shorted / closed / directly connected
Infinite ohms = open/ no path
Try to remember to say either Infinite or zero instead of “no ohms” or “none” to avoid confusion
