4WFB120, 4WFB350, 4WFB1K 4 Wire Full Bridge Terminal Input Modules
5.1 Edlog
Dataloggers that use Edlog include CR510, CR10(X), 21X, and CR7. The
Edlog instruction that measures strain gages is Instruction 6 – Full Bridge.
The Input Locations assignments used in CR10(X), 21X, and CR7 Examples
are listed in Table 5-1.
