Measuring
For static measuring the Measuring Head is clamped and switched on. After the Handheld Unit
has been switched on, the immediate tension is recorded and indicated on the display.
8.3.2 Dynamic
Measuring
After the Measuring Head has been
clamped in a parallel plane (see
chapter 8.2.2) the stand with the
magnetic base must be fastened to
the support of the tool machine and
positioned in such a way that the
lateral distance between the

of the cover and the edge of the
flattened part of the stand should be
1-2 mm approximately. The stand
should end with the yellow cover of
the Measuring Head before the
steel part begins.

force is determined and shown on the display. When the chuck is rotating at the same time, the
display shows besides the gripping force the corresponding actual number of revolutions
