Flow Chart for Error Analysis “Error while Determining the Base Line”
For general information about the base line determination please refer also to
=> Instruction manual Software LF8,
Appendix A, Tests and calibrations, Determining the zero-point/base line!
DANGER DISCONNECT FROM THE MAINS BEFORE ANY REPAIR WORK
Disconnect the PowerCube from the mains before starting any repair work.
If checks and adjustments of the PowerCube-module can only be carried out by
removing the cover AND when connected to the mains, it will be pointed out
especially in the respective description. When performing these procedures be
aware that parts inside the device may be current-carrying.
