5.2 CRBasic
Dataloggers that use CRBasic include our CR800, CR850, CR1000, CR3000,
CR5000, and CR9000(X). CRBasic uses the StrainCalc Instruction for
calculating strain from the output of different full bridge configurations:
StrainCalc(Dest,Reps,Source,BrZero,BrConfig,GageFactor,PoissonRatio)
Source is the variable holding the current measurement, BrZero is the zero
measurement; this instruction uses the results of the full bridge measurement
instruction (multiplier=1, offset=0, mV/V) directly. The code for the Bridge
Configuration used with the 4WFB module is -1. Enter the actual gage factor
for GageFactor. Enter 0 for the Poisson ratio parameter which is not used with
this bridge configuration.
