*3.3. Indication*

The developed measurement system accommodates up to eight sensors and has a maximum single-sensor sampling frequency of 1299 Hz. Considering all four tested sensor units, experimental evaluations show the system's functionality to be *err*rel = −0.34 ± 1.28% in uniaxial and *err*rel = −0.90 ± 0.98% in diagonal test-rig motion. Measurement errors were found to be uncommon, of known types, and not critical to the measurement.
