⇒ The calibration is finished and the correct weight value is now displayed in the SIWATOOL
program.
Receiving calibration parameters
During the calibration, the SIWAREX internally changes its calibration digits. This means that
SIWATOOL now has obsolete parameter values. Obsolete calibration parameters are marked
in red.
The calibration parameter (DR3) must be read back in order once again obtain the calibration
digits in the SIWATOOL which are consistent with the SIWAREX.

● Right-click on "Calibration parameter (DR3)" and select "Receive data record".

Checking the scale following calibration
If the scale is to be used for business purposes only, check it as follows:
1. The scale is unloaded and the display shows "0 kg".
2. Place one or more known test weights on the scale. To check other weight points of the
scale in addition to the calibration weight, do not use the calibration weight.
3. Check the displayed weight value in the SIWATOOL program.
4. Remove the test weights from the scale.
5. Check that the display of the scale is 0 kg again.
7.4.3.3 Automatic calibration (without calibration weight)
The scale can also be calibrated without a weight. To do this, the parameters marked in bold
in DR3 / basic parameters are checked or entered, and the data specific to the load cells are
specified in DR10.
