Automated balancing/nulling software tool for Acra KAM-500 modules. Bridge Balancer 3 is used to automatically balance/null up to thousands of bridge outputs acquired using a distributed Acra KAM-500 architecture. Balancing the signal before it reaches the instrumentation amplifier allows the maximum gain to be used in the signal conditioning channel. Acra KAM-500 modules such as the KAD/ADC/109, KAD/ADC/114, and KAD/ADC/118 support this feature.
