Hi Richard,
You may use the following method:
'assuming those sensor have the following rating:
'sensor 3: rated output of 2.000 mV/V @ 5000 lbs which mean 2000 ppm for 5000 lbs (you need to check sensor calibration document).
'sensor 4: rated output of 2.100 mV/V @ 5000 lbs which mean 2100 ppm for 1500 lbs (you need to check sensor calibration document).
'scaling entry to convert ppm to lbs
'writing style Sn=targetlow,targethigh,readlow,readhigh
S1=0,5000,0,2000"lbs"
S2=0,1500,0,2100"lbs"
'Offset reading (it will run at the start of program to set an offset value, remember to remove any load from load cell during this phase)
3BGI("Offset Balance~ppm",=11CV,W)
4BGI("Offset Moule a rebond~ppm",=21CV,W)
RA1M
'Raw reading, this is the reading without an offset (because you do not need these figures, they must be set as working channels).
3BGI("Raw Balance~ppm",=12CV,W)
4BGI("Raw Moule a rebond~ppm",=22CV,W)
'Actual readings are obtained by negate raw reading with the offset and apply the scaling
13CV("Balance~lbs",S1)=12CV-11CV
23CV("Moule a rebond~lbs",S2)=22CV-21CV
If you are using dEX, you have to put two current bridge channel for the offset reading under "On Logger Activation"
