Probably -/5, if anyone can figure out what that is.

Duplicate thread! If you don't get an answer the first time, perhaps you didn't ask the question very well. Perhaps you provided insufficient information.

MF = (main ctr x main ptr x meter constant) / (meter ctr x meter ptr)

Work it out from there once you have determined all of the numbers.
