The usual three-wire lead hook-up self-temperature compensating 

 gages could not be used since the Gilmore Strain Gage Plotter requires a 

 dummy gage in the circuit. The urgent need for the results necessitated 

 the use of SwRI stock strain gages, and since insufficient aluminum com- 

 pensated gages were available, some steel compensated gages were used. 

 Consequently, one of each of these two types of gages was installed on the 

 aluminum dummy blocks inside and outside of the pressure facility and 

 appropriately wired into the circuits.
