F.3.1.9 Form 12 Meters—The Form 12 meter has 2 current coils and 2 stators. They
are self-contained Form 5 meters. To perform a meter verification test on these meters, you
will need both of the 5000-MV-SC2-2 probes from Spinlab. It requires 1 test to determine
the accuracy of the meter. Also, the clamp-on CTs have a lower limit of .5 amps. This
means that each conductor on a form 12 meter will have to be carrying .5 amps or more to
gain the accuracy of .2%. The hookup is as follows:
