How to check electricity at a campground

I just read a campground review where the RV-ers checked the electricity at 3-4 sites before they found one that was good.

We have been RV-ing for many years. We don't check but I think it is about time for us to do so. I did a search here on the forum but I could not find any posts relating to checking the electricity. I am not using the correct terminology, I am sure.

Is this a special meter or something else? I would like your recommendations for one, if possible.

Thanks!

. To answer your question directly all you need to check the post at your campsite is a multimeter. If it is a 50 amp plug set the meter to 200 v and check from ground (round hole at top) to vertical slots left and right it should read 120 volts check other vertical leg should be the same. Check top ground ( round hole ) to vertical ground directly under top round and that should be zero volts. Set meter to 700 v scale and read voltage across the two vertical legs should read 240 volts. Do you have a muti meter? If not you can get one at Harbor Freight for free with any purchase. If voltage is less than 107 v I would look for another site if you want to run AC.
