Description:
- Reading gives the state of AC excitation.
- Writing '1' enables AC excitation.
+ This attribute, if available, is used to enable the AC

- Reading gives the state of the bridge switch.
- Writing '1' enables the bridge switch.
+ This attribute, if available, is used to close or open the

+ In bridge applications, such as strain gauges and load cells,
+ the bridge itself consumes the majority of the current in the
+ system. To minimize the current consumption of the system,
+ the bridge can be disconnected (when it is not being used
