Operation
6.1
Range Selection
It is advisable to use charge amplifiers with sensitivity ad-
justment (e.g. Type 5070A...) with the 3-component force
sensors.

Measuring Small Force Changes
The piezoelectric method of measurement allows very
accurate measurement of small force changes when there
is large preload present at the same time. When, for exam-
ple, fluctuations
F
z
of about 5 N are superimposed on
a force F
z
of about 1 000 N, the following rules can be
applied:
