3.6 Creating a material characteristic
The tension meter has been calibrated on material 1 and material 2 according our
SCHMIDT procedure for a vertical material path and cannot be deleted or overwritten.
The the materials and diameters are given in chapter 2. Factory calibrations using custo-
mer supplied materials follow the same procedure. In this case, however, the calibration
on Schmidt material 1 and 2 is omitted
The material characteristics 1 and 2 have been preset in the factory and cannot be
overwritten. For these material characteristics, you can only change the damping
factor, the alarm function setting, and the limit values.
3.6.1 Calibration procedure
Calibrations of the tension meter are performed according to the SCHMIDT factory
procedure using weights that correspond to 10 %, 50 %, and 90 % of the measuring ran-
ge. In 95 % of all industrial applications, the SCHMIDT calibration has been proven
to provide the best results. In particular, it is suitable for comparative purposes.
If the material to be measured differs significantly from the SCHMIDT calibration material
in material type, diameter, rigidity, shape, etc., we recommend to perform a calibration
using customer-supplied material. In addition to the two factory-preset materials, you can
save up to 9 additional materials.
The material thickness unit used for the calibration is the same as currently
selected in the „Settings menu“.
It is not possible to overwrite the factory calibrations.
Calibration Units and Calibration Points
- You can select Newton or Kilogram as the unit of the calibration weights.
- For the calibration of the tension meter, three calibration weights are used. For
example, if you select 10 %, 40 %, 70 % for the calibration, the weights must
correspond to 10 %, 40 %, and 70 % of the measuring range.
In this example, you need the following weights for the DTX-1000:
Calibration in Newton: 100 cN, 400 cN, and 700 cN
Calibration in Kilogram: 100 g, 400 g, and 700 g
The measured values are displayed in the unit set in the „Settings“ menu, inde-
pendent from the unit that was used to calibrate the material characteristic.
So that they are available when you verify the calibration later or repeat the
calibration after a factory reset.
