11.10 Floating Measuring Sensors
In the case of floating measuring sensors, potential differences can occur be-
tween the individual measuring sensors and in comparison to M. These po-
tential differences can also be caused by malfunctions or the spatial distribu-
tion of the measuring sensors. Ensure that U
CM
does not exceed the permitted
value (e.g. by using an equalizing conductor).
