4 4 2 Friction test
In order to set the pincer jaws in motion, a minimum force is required to overcome friction. since this force does
not act on the clamp during crimping, it is determined during the friction test and compensated accordingly during
crimping.
During the friction test, the pincer closes empty (without parts being crimped between the pincer jaws) and thus
determines its internal friction.
4 4 3 Force test (standard-setting)
The force test is carried out in order to match the displayed force of the Control Unit to the actual force at the pin-
cer head. a Cal 01 is required for the force test. The Cal 01 determines the force applied to the pincer jaws.
During this test, the closing force sensor sKs0x simulates the closing force and the Cal 01 records the force for
calibration purposes. The displayed force can be entered either in the PC software or directly on the Control Unit.
at least 2 iterations with 3 crimping operations must be performed and their mean value transferred. an iterative
determination of the closure force is more precise.
If a subsequent check (after the determination) of the closure force reveals a deviation that is greater than
Ho 2000-4000: ±100 n, Ho 5000-7000: ±170n n, Ho 10000: ±250 n, the procedure must be repeated.
4 4 4 Two-stage guided force test
In the PC software it is possible to enable the two-stage guided force test. This test is safer, more accurate and
more guided than the force test described previously. enabling the two-stage guided force test will supersede the
standard-setting force test (
).
In the first stage of the two-stage force test, a low force is produced in the pincer. Providing a force correction is
needed only if the actual force value measured with Cal 01 is outside of the range displayed on the ePC 01.
The second stage of the two-stage guided force test is performed at 100% of the current aPn closing force.
Three closures must be repeated two times in order to proceed with the gap test. Consequently, a total of a mini-
mum of six closures will be carried out in this stage.
In conclusion, a total of at least seven closures are performed in the entire two-stage guided force test.
4 4 5 Gap test
The pincer body can be equipped with different heads. after a change, each pincer head must be recalibrated.
The displacement measuring system is compared with the pincer jaw travel.
During the gap test, a gap gauge is held between the pincer jaws. The pincer is calibrated based on two gap
gauge values (i.e. 2 mm and 4 mm). Two closures are carried out for each gap gauge. Consequently, a total of four
closures will be carried out.
