Continuity test on live circuit

[lightspeed]

I was using my Fluke 117 to test for continuity between a light switch hot wire and another outlet hot. I noticed it stayed ringing even after the probes were removed for a second or two.

I do understand in retrospect that continuity tests should not be done on energized circuits.

Is it possible I've damaged the Fluke or somehow compromised its accuracy?
Thanks in advance

There's a component inside (called a PTC) in it that heats up under stress and protects the meter when it gets hot enough.

It has to cool down again for the meter to return to normal and that takes a while.

Is it possible I've damaged the Fluke or somehow compromised its accuracy?

Yes, PTCs wear out, but it's not very likely if you only did it once.

I do not know what the Fluke 117 is doing that would cause that, but before we had PTCs, multimeters used other methods to protect their ohms converter circuit which did not have any cool down time.

Thank you I feel more confidence in my equipment now
