( − 28,000 to 28,000) for two points in the scale (the 100% value and 0%
value).
Value for 100% set by user
(Scaling point 2)
Value for 0% set by user
(Scaling point 1)
Note 1. The default values are 0 and 28,000.
2. Reverse scaling, where the 0% scaling value is higher than the 100% scal-
ing value, is also supported.
The scaling function is equipped with offset compensation, which can com-
pensate for any error that occurs during scaling. The offset amount is added
to the scaled line as shown in the following diagram. The offset (error) value
can be input between
overflow does not occur. The High Limit is 7FFE hex and the Low Limit is
8000 hex.
Note The offset value can be set even when using default scaling.
Upper limit 7FFE hex
100% scaling value (32766)
0% scaling
Lower limit 8000 hex (−32768)
