2 of the strain gauges will be in compression (A and D) and the resistance will decrease and 2 will be in tension (B and C) and their resistance will increase. @Adam Equipment Company 2005... - Page 12 The circuit of a typical load cell is shown below. A method to check the basic function and integrity of a load cell can be done using an ohmmeter and voltmeter with up to a 10volt power supply. @Adam Equipment Company 2005...
- Page 13 CBC/CBW scales amplify the input by 200, and change the no load voltage to about +2.5V. The amplified and offset voltage is measured at pin 6 of IC7, the INA118P amplifier IC. This voltage is sent to the filter and then to the A/D converter. @Adam Equipment Company 2005...
