I'm looking for an easy way to verify that the metal casing of appliances are grounded, such as a range, without needing to disconnect and pull them out.
If I use a multimeter set to continuity and place one probe on a wall plate screw (that I know for sure is grounded), and the other probe to the metal frame, is this a safe way to check that there is a complete ground connection that meets at the panel? I know this won't verify that the wiring is sufficient, but just checking for a complete connection right now.
The meter itself, on continuity mode, puts out about 0.12mA and 0.5volts.
Thanks for any comments.
