Example
 Example 1
Assume S
1
= 500, S
2
= 168, S
3
= -4 When X0 = ON, after executing SCAL instruction, you can
obtain the required ratio in D0.
Calculation: D0 = (500 × 168 ) ÷ 1000 + (-4) = 80

 Example 2
Assume S
1
= 500, S
2
= -168, S
3
= 534 When X0 = ON, after executing SCAL instruction, you
can obtain the required ratio in D10.
Calculation: D10 = (500 × -168 ) ÷ 1000+ 534 = 450
