I suppose that it's a problem with the FP5. The FP5 are delivered by FATAR
unadjusted (i.e. the resistance range and consequently the voltage range is
not the same for each FP5 from the factory). That's why we open each single
FP5 and adjust it so that 0V are generated in the low position and about +8V
in the upper position. Then the FP5 is equipped with a label at the bottom
("DOEPFER FP5" and a picture of the FP5 together with a garbage can symbol).
Please check if your FP5 has this label available.
