4. Calculate Offset.
Reading = Scale x Input + Offset
Offset (n) = Reading (n) - Scale (n) x Input (n), where n is an integer
The commands for these points are 3D to 45 (Table 5.4)
4.1 Offset 1 = 28 - (28 - 0) / (500 - 0) x 500 = 0
RDGOFF1.19~0 = 0 Dec = 0 Hex
RDGOFF1.22~20 = 2 (DP+2)
RDGOFF1.23 = 1 (Offset is negative)
Send command: *W3DA00000
4.2 Offset 2 = 110 - (110 - 28) / (1000 - 500) x 1000 = -54 x E0
RDGOFF2.19~0 = 54 Dec = 36 Hex
RDGOFF2.22~20 = 2 (DP+2)
RDGOFF2.23 = 1 (Offset is negative)
Send command: *W3EA00036
4.3 Offset 3 = 250 - (250 - 110) / (1500 - 1000) x 1500 = -170 x E0
RDGOFF3.19~0 = 170 Dec = AA Hex
RDGOFF3.22~20 = 2 (DP+2)
RDGOFF3.23 = 1 (Offset is negative)
Send command: *W3FA000AA
4.4 Offset 4 = 444 - (444 - 250) / (2000 - 1500) x 2000 = -332
RDGOFF4.19~0 = 332 Dec = 14C Hex
RDGOFF4.22~20 = 2 (DP+2)
RDGOFF4.23 = 1 (Offset is negative)
Send command: *W40A0014C
