Number of Secondary Lead Passes Through Sensor]. The Honeywell E-Mon 25
amp HV kWh meter with 5 wraps of the high voltage CT secondary will have its
multiplier calculated by the formula shown below.
EXAMPLE: CT = 400:5 = 80:1 (CTr = 80)
PT = 4200:120 = 35:1 (PTr = 35)
Wraps (Passes) = 5
METER MULTIPLIER = PTr x (CTr/Wraps)
35 x (80/5)
35 x (16) = 560
