Summary
-
1.
The theoretical possibility of split balancing ac bridges with zero indicators connected across the bridge diagonal is demonstrated. This is rendered possible by connecting the balancing elements in such a manner that their adjustment does not affect the current in the corresponding branch of the bridge.
-
2.
Above connection of balancing elements eliminates in the case of automatically balanced ac bridges (or at least greatly reduces) the interaction of the balancing circuits.
