WIRING
As shown below (a), the internal circuit of the circular pattern strain gage has two adjacent corners of the full bridge left open. The open bridge corners are left for the introduction of zero-shift versus temperature correction, and subsequent restoration of zero balance. The linear pattern (b) has a slightly different circuit arrangement but the purpose is the same.

and TC-116 for circular pattern strain gages and
