Binary Code:
Send command: *W1481E858 (scale = 81E858)
Offset:
Offset is found in the following equation: Reading = Scale x Input value + Offset (Y=mX+b)
or the equation can be rewritten as: Offset = Reading – Scale x Input Value (b=Y-mX)
1. Obtain the Offset Factor
Offset = 100 – (0.0125 x 10000) = (-25)
2. Rewrite the Offset Factor as an integer times an exponent
–25 x E0
3. Then encode these values
25 Dec = 00019 Hex Offset Data (RDGOFF.19 ~ 0 value stored into bits 0 – 19)
E0 is represented as RGDOFF.22 ~ 20 = 2 (DP+2=0+2)
Offset is negative represented RDGOFF.23 = 1
Binary Code:
Send command: *W03A00019 (offset=A00019)
