5.3.4.1 Break testing 1 - diagramm
The test procedure serve to appraise the breaking force by pressing continuously at a uniform speed the
measurment object, while the readings get recorded continuously with a frequenz of 100Hz and than
saved in the result memory. The operation consists of following steps:
1.
Research of the HOME position at the speed v

2.
Movement with the speed v

up to the position START directly above the object;
3.

4.

5.
Start of the bread detection at x% of the nom.force of the load cell;
6.
Ride up to bread with the speed V<Bruch>.
7.
End of measurment at x% of the maximum force value and return to the home-position.
8.
Indication of the peak value at the position of the break.
9.
Test seies in the reading memory.

5.3.4.2 Break testing 2 – Peak values
The inspection process serves to appraise the breaking force at various successive tests by pressing
continuously at a uniform speed the measurment object, while the readings get recorded at the
moment of the break and than saved in the result memory. The operation is indentical with the one of
breaking test 1, only that the measurment values in the moment of the break get recorded and the
number of test cycles (number of specimen) is predefined.
