•
You must make these settings for a direct connection or for a connection with current trans-
formers.
•
The selected measuring range must be greater than the secondary rating of the current
transformer!
•
The accuracy of SICAM P (see table 3-3) is based on the selected measuring range.
•
The determination of this range indicates the maximum current value that can be displayed
on the device.
Note
When you change the current transformer settings, the power calculation in the device has to be
reset.
