of the platform share a greater weight. This proportion is about 2：1. In order that the
platform shares a uniform force, we require the ISN max. Value minus min. value of the
four load cells on margin less than 400; Likely the max. ISN value minus min. ISN
value of the four load cells in center less than 400.(If the scale has 8 load cells, then
there are 4 load cells in the center). (Note: if all the load cells are confirmed to be
pressed tightly, it is also acceptable if the max. ISN value minus min. ISN value is
inside 800).
（2）Here is an example: Press "Check" to inspect the ISN of the load cells (For details,
please refer to User's Manual chapter 4)
A platform 60T（3.4×14m） ，deadweight 10T（As following diagram）

Trough inspection their ISN value are

difference is usually no more than 400kg. It is also right for load cells in the center number
②、 , but their ISN value should be twice of the load cells on margin (approximately).
⑤
In case the ISN value is too big or too small, then the load cells under the platform are not
levelly installed. Gasket should be added or removed until fitting the above condition to
make the platform level.
4、Four Corner Adjustment
Manual
Corner-Rectify: After the platform has been adjusted level, use weight
①
(Car for example), which should be as nearer to the full capacity as possible, to press it.
After 5-6 times' come and go pressing; the parts of the platform become stable. Then put
certain weight on platform to carry on previous calibration. After that, discharge the
weight and begin Corner-Rectify. Use one certain weight to press the corner. Generally,
the error is smaller than 1d. If you still need smaller error, you can adjust corner-rectify
coefficient K If the displayed value is bigger than the actual value when pressing a
weight right upon a load cell, then adjust the corner-rectify coefficient of this load cell to
be smaller (the load cells are already noted their addresses during installation); If the
displayed value is smaller than the actual value then adjust the corner-rectify coefficient
of this load cell to be bigger.
For example, corner
