Multi meter and pedestal power

How does one use the meter to test 30 amp voltage? Which post is hot and which is neutral, looking straight at the pedestal? What would a safe low and high voltage reading be?
thanks

In answer to your questions, the left hand slot would be the Hot and the Right hand slot the neutral. Voltage should be 120 volts with the National Electric Code allowing a 5% variance which would be +/- 6 volts. Given the possible variance of a meter you can be pretty comfortable with a voltage between 112 volts and 128 volts. Anything higher or lower is probably going to be trouble, since voltage will vary slightly over time and you are probably not going to be testing at the absolute highest or lowest reading of the day.
