6.0 CREATING A MATERIAL CHARACTERISTIC

The tension meter has been calibrated on material 1 according our factory procedure

for a vertical material path and cannot be deleted or overwritten. The the materials and

diameters are given in Section 2. Factory calibrations using customer supplied materials

follow the same procedure. In this case, however, the calibration on Schmidt material 1

is omitted

NOTE: The material characteristics 1 has been preset in the factory and cannot be

overwritten. For these material characteristic, you can only change the damping factor,

the alarm function setting, and the limit values.

6.1 Calibration procedure

Calibrations of the tension meter are performed according to the factory procedure

using weights that correspond to 10%, 50%, and 90% of the measuring range. In 95%

of all industrial applications, the factory calibration has been proven to provide the

best results. In particular, it is suitable for comparative purposes. If the material to be

measured differs signicantly from the factory 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.

NOTE: 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

NOTE: The measured values are displayed in the unit set in the Settings menu,

independent 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.
