HX711 and weight cell, throws large negative value

I have successfully installed 3 weight cells to Particle Photon, using HX711. The fourth weight cell shows large negative values e.g.-69798 when a certain amount of weight is added. The weight cell should be able to measure up to 10kg, as do the other three weight cells.

Is there a possible explanation for this outcome? When lowering the weight (on all four weight cells), which are connected to a single plate, the values look good. When adding about 3-4kg on the plate, the three weight cells shows good values while the fourth shows large negative values.

The cell is being loaded in the opposite direction. Up needs to be down and down up. Also please check your wiring first and then try the above.

Simple solution. Just turn the load cell by 180 degree in vertical axis. Sometimes the manufacturer puts the sticker other way around. This should solve.
