: "A force sensor is not placed on the floor."

as evenly and consistently as possible. Avoid a point
load near the edge of the plate since this can also
cause this error message.

Possible causes:
• Uneven floor
• Defective sensor in the force measurement plate

nised within the outer blue frame; restart the mini-
computer in case of incorrect exposure).
Take corresponding steps to prevent backlighting
