4 weight sensor  connect with 1WT?

When using multiple high-range load cells:

1. Wiring, such as using 4 load cells to measure the same object, you can connect the power lines and signal lines of the 4 sensors in parallel, connect them to the weighing module, and connect these 4 load cells are used as one load cell.
2. Measure the resistance value between the signal lines of the load cells connected in parallel to see if it reaches 200 ohms. It is best to choose a sensor with a value greater than 200 ohms. (The manual of our weighing module requires that the single-channel load impedance is not less than 200 ohms)
3. When you calibrated weight,please set the The weight of the weight should be greater than one-third of the sensor range, and the calibrated weight will be more accurate.
4. For large-range sensors, the material display accuracy does not need to be too high. If the unit is kg, it can display 1 decimal point. If the display accuracy is too high, the calibration will fail. (In the case of using three 500kg load cells, when the display accuracy is 3 decimal points, the calibration has not been successful. After the display accuracy is changed to 1 decimal point, it can be calibrated normally)
