    8-2 HOW TO COMPENSATE TEMPERATURE INFLUENCE ON LEAD WIRE (3-WIRE SYSTEM CONNECTION) When a lead wire is extended from the gage to a bridge circuit using a SELCOM gage as shown in the following, resistance change of the lead wire caused by temperature is viewed as an apparent strain. With this state, it is not available to fully exert effective features of the SELCOM gage in strain measurement.
