| Strain Indicators | |
 |
 |
| gages on top of beam (compression side) channel 1: axial gage (negative strain) channel 2: transverse gage (positive strain) |
gages on bottom of beam (tension side) channel 1: axial gage (positive strain) channel 2: transverse gage (negative strain) |
 |
These are quarter-bridge setups, where each gage is wired between P+ and S-, and a jumper runs between S- and D120. |
