WM002C Dynamic Loading Module
Please check the foundation condition before installation: the plane drop of each installation point should be controlled within 3 mm, and the levelness of the same foundation surface should be controlled within 1mm/m; the bearing capacity of the installation base must be greater than the measuring range of the sensor.

5. How to install a weighing module
A: After the weighing platform and all installation accessories are ready, please install the weighing module product and the weighing platform together;
B: There are screw holes on the upper and lower mounting plates of the weighing module for fixing the sensor module. Please do not loosen any nuts on the weighing module product during installation;
C: After all the installation work is in place, please completely loosen the A and B nuts when preparing to debug or use the weighing platform so that the platform is in a completely free-floating state.
6. Installation and debugging precautions
(1) During the installation and debugging process, it is not allowed to cut the original cables on our products, otherwise it will cause signal errors;
Do not use the sensor body as a force support point during our installation, otherwise it will cause signal errors;
(2) After all products are installed in place, loosen the two nuts (A, B) on the top of the module screw so that the weighing platform is completely floating;
If re-transportation is required, please tighten nuts A and B again to protect the sensor from external damage;
(3) The full scale range of a single sensor is 1.1 tons. Do not apply more than 150% of the safe overload range to a single product;
(4) Please check the foundation condition before installation: the plane drop of each installation point should be controlled within 3 mm, and the levelness of the same foundation surface should be controlled within 1mm/m; the bearing capacity of the installation base must be greater than the measuring range of the sensor.
(5) This set of products is a high-precision weighing unit. During installation, transportation, debugging, and use, please prevent anyone from standing on the sensor or weighing platform. It is prohibited to use violent actions such as kicking or stomping, otherwise the product will be damaged. Our company is not responsible.
7. Debugging
(1) Before the product leaves the factory, the error between each product has been calibrated with high precision and no adjustment is required;
(2) All parameters of the weighing controller have been set before the product leaves the factory. Please do not modify the internal parameters;
(3) After the weighing platform is completely installed and the nut on the top of the module has been loosened, please reset the instrument to zero (press and hold the zero key). Then it can be used for normal weighing. It has been calibrated with standard weights before leaving the factory. Do not recalibrate.
(4) After use, if you need to recalibrate, please use a standard weight or an actual accurately weighed object as a weight reference. The recommended weight is 50% of the measuring range.
During installation, debugging, and use, if you have any questions, please contact our company in time to avoid improper operation and damage to the product. Thank you for your understanding and support.
