13.8 Adjustment of the measuring force
1. The instrument is supplied with a standard measuring
setting of 1 N. The measuring force adjustment screw is
located inside the column protection profile on the
measuring carriage. The screw can be reached through
the opening in the protection profile. Use a 2 mm allen
key for adjustment. By turning the screw clockwise, the
measuring force will be increased.
2. Check the measuring force using a dynamometer (force
gage). Bring the dynamometer lever in contact with the
measuring insert. Move either the lever or the insert until
the sound of the acoustic signal and read the measuring
force on the dynamometer. Repeat the same procedure
for the opposite movement. Compare the results and re-
adjust if necessary. The measuring force must be equal
in both directions.
13.9 Adjustment of the floating probe suspension
To guarantee a constant measuring force in both directions (measurement upwards and downwards), adjust
the floating probe suspension according to the measuring anvil/ holder used.
1. The screw for the adjustment of the floating probe
suspension is located inside the column protection profile
on the measuring carriage. The screw can be reached
through the opening in the protection profile. Use a 2 mm
allen key for adjustment. By turning the screw clockwise,
the probing will be relieved. This means, that the
measuring force for probing in downwards direction using
the standard insert will be lower.
2. To test the floating probe suspension, use a
dynamometer. Bring the dynamometer lever in contact
with the measuring insert. Move either the lever or the
insert until the sound of the acoustic signal and read the
measuring force on the dynamometer. Repeat the same
procedure for the opposite movement. Compare the two
results and re-adjust if necessary. Both directions must
be balanced (equal values).
