• When electricity meter used is specified by pulse constant
The connection configuration is shown below.
For the electricity meter specified by pulse constant, the power consumption indicated by output
pulse must be corrected by VT/CT ratio. In this case, the settings are as follows:

Equipment conditions:
VT ratio=1 (not used), CT ratio=500(2500/5 A), electricity meter=3,200 pulse/kWh
Set value:
Electricity meter pulse setting=6 (3200/ [1 × 500]), Pulse setting=0.9375 (6 × [1 × 500]/3200) For
