^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		excitation mode found on some converters. In ac excitation mode,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		the polarity of the excitation voltage is reversed on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		alternate cycles, to eliminate DC errors.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		This attribute, if available, is used to close or open the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		bridge power down switch found on some converters.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 		In bridge applications, such as strain gauges and load cells,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 		the bridge itself consumes the majority of the current in the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 		system. To minimize the current consumption of the system,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 		the bridge can be disconnected (when it is not being used
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		using the bridge_switch_en attribute.
