Hello every one
I am trying to make a weighing machine using load cells with a maximum capacity of 500 Kg.For this i made a rectangular platform with 4 load cells on each corner and i connected the +ve excitation to +5 v and the -ve excitation to GND. Instead of processing each load cell output separately i connected the output together and gave to an ADC input. Now the problem is that the output is not same for the same load when placed on different points of the platform.So i would like to know whether there any other better methods for connecting load cell outputs together.
Many thanks in advance
