•For dynamic measurement, the axis of rotation of the
measuring head must always lie on the axis of rotation of the
machine spindle.
•The product may only be used within the scope of its technical
data.
•The product is intended for industrial and industry-oriented
use.
•Appropriate use of the product includes compliance with all
instructions in this manual.

Functional description and operation
Overview
The operating principle of the measuring head is based on several
internal strain gauges. The applied clamping force is converted
into an electrical signal and evaluated by the electronics. A
wireless data link transmits the data from the measuring head to
the tablet and visualizes the measured values in the APP.
Measuring head
General
The measuring head consists of the base body with integrated
sensor system and electronic processor, as well as the respective
intermediate pieces for the clamping diameters Ø72 mm, Ø96 mm
and Ø136 mm. The arrow on the cover and also on the bottom of
the measuring head symbolizes the measuring jaw, which must
always rest on a jaw of the clamping device to be measured.
1 measuring jaw with indicator arrows
CAUTION
Measuring jaw always in force flow!
Otherwise the measured values are not meaningful.
