Installing knuckle eye, ZKM and threaded adapters:
• Screw the knuckle eye thread into the transducer's inside thread until it
reaches the stop, then loosen it by one turn.
• With Z4A/500kN in addition: turn the knuckle eye to align the bushing holes
with the knuckle eye apertures.

For dynamic loading, Z4A transducers must be installed without play.
Knuckle eyes only have limited applicability for dynamic loading, as with
dynamic alternating stress, the pivoting bearings increase their bearing
clearance, thus falsifying the measured value. With the increased load cycle,
there is a risk that the knuckle eyes could be destroyed. For this type of
loading, we recommend using flexible tension bars or pressure bars.
To install the transducers without play, they must be sufficiently prestressed
and locked with the mounting accessories (knuckle eyes, tension bars or
pressure bars).
