What is a "Grounding Meter"? I have a job in which the spec states that I must provide a grounding meter for each panel as per the 2011 NEC. Huh?
I just searched NEC 2011 for the term "Grounding Meter". Acrobat reports no matches were found.What is a "Grounding Meter"? I have a job in which the spec states that I must provide a grounding meter for each panel as per the 2011 NEC. Huh?

That is correct... but it demonstrates how two consecutive words can have an entirely different meaning outside the context of their usage.Unless I am reading that wrong, which wouldn't be the first time, that is just talking about grounding the meter can
How true--a misplaced or missing punctuation mark--Like the guy who was smoking in an elevatior and gotr ticketed back in the day when they first started the no smoking thing, The sign said :No Smoking Allowed"-- As he was a literature instructor at the local collage he argued that the sign meant " No Smoking isAllowed" meaning that if you don't want to smoke you don't have to
Many anti-smoking laws require sign placement. In some cases, lack of signage means smoking is permitted in the area. Another fault of signage is full disclosure of intended area. Typically signs are in regards to the other side of the sign. If you walk into a room with a no smoking sign on the far wall, it could be interpretted as meaning you cannot smoke on the other side of the wall, but you can in the room you just entered. Most anti-smoking laws are explicit in that the sign has to be placed at the entry to the area. Another example I have seen is no parking and no trespassing signs.That's kind of ambiguous, and I don't agree with the prof.
Looking at the phrase, (it's not a sentence) 'No Smoking Allowed' and taking it to mean 'It's permitted not to smoke', would mean the proper phrase would have been 'No Smoking Required', or 'It's required not to smoke'.
Signs don't have to follow perfect English and grammar rules. The prof knew what the intent of the sign was just like anyone else that could read. The story doesn't mention how it turned out. I'll bet the prof still had to pay the ticket as his twisting of the meaning of the sign does not negate the fact that he was smoking in an area that it was illegal in. Even though, as the prof read it, not smoking was one option, the fact remains that smoking was not an option. There could have been no sign and smoking in the elevator would have still been just as illegal as with one.
