• Linearisation

The precision of the testing machine can be increased by means of linearisation. If the table is empty, all

points have to be run. This is not necessary if you want to correct individual points´.

Procedure:

The piston is extended.

(force free)

0% calibration value is read in. The display is set to zero,calibration value to 2%.

Now, as described under point "Manual operation" run to 2% of the max. force.

2% calibration value is read in and is increased to 4%. Run machine

up to 4% according to the calibration instrument.

4% calibration is read in and increased to 6%. Apply same procedure

for 10, 20, 40, 60, 80, 100% as in step 2 for 4%.

At the rst recording of the linearization values, all points have to be run. If a wrong measuring value is

read in, press DI or DE to switch to the old position. Press ENTER again when the correct calibration

value appears. After the last input (100%) the message “table completed” appears.

select the next higher calibration value.

select the next lower calibration value.

Abortion with storage of the linearisation value

Abortion without storage

! Attention: if the linearisation is executed it is not allowed to calibrate anymore!
