Meter reading display CT Ratio multiplier

[jwu]

When taking a manual reading through the LCD display is it required to apply a CT ratio multiplier to derive the true scaled up usage?

Specifically, to Schneider models

PM2220, PM2220R, PM5560,

A9MEM3250 - NMI, A9MEM3255-NMI

Much appreciated.

Hi @jwu ,

The electrical parameters displayed by the meter (current, power, energy, etc.) are already scaled taking into consideration the CT ratio.
