    2 Due to variations in materials, manufacturing and external forces, the strain gage values may change.  These changes will affect the zero force reading for each beam differently.  To maintain consistent results, the zero force reading needs to remain constant.  Each strain gage is equipped with a balancing potentiometer.  Adjusting the balancing potentiometer will change the strain gage output for that finger.  Adjust the BH8-262 balancing potentiometer until the no-load value is between 100 and 140.  Use the following steps to zero the strain gages:
