ME96 returns fixed data determined for each
measuring items. (About fixed data, refer to Table
7.2 to Table 7.12)
(Example:When selected phase 1 current (Inst),
channel No.is 21h, group No. is 01h.)
<Multiplying factor>
Multiplying factor is fixed for each items according to
phase wire system, primary voltage and primary
current.(For details, refer to Table 7.22)
