I´m making a force plate with 4 500 Kg load cells. I put load cell on each plate corner. I made an instrumentation circuit for every load cell with AD620 and LM358. The LM358 was used to fix the instrumental amplifier offset error. Afterward used an ADC (ADS1115) to read weight readings for each load cell and sending all measurements to ESP32 using I2C protocol.
How can I calibrate all load cells without using a summing circuit or Hx7111 module for obtaining total weight voltage?.
