Caution
• 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.
Example
CT rating: 500 / 1 A
Measuring range 1.2 A: Maximum display range: AC 0 A to 600 A
Measuring range 6 A: Maximum display range: AC 0 A to 3000 A
