Product overview
2.2 Functions
Example
The following values result, for example:
Table 2- 3
Base measuring range
S7 format
Scaling of measured values
As shown in the table, -10 V corresponds to 1.00 and +10 V corresponds to 7.00.
Combination with measuring range adjustment
If the measuring range adjustment is enabled in addition to measured value scaling, first the
measuring range is adjusted and then the representation of the measuring range scaled. The
table below shows an example of the combination of measured value scaling and measuring
range adjustment.
Table 2- 4
Measuring range adjustment
S7 format
Scaling of measured values
As shown in the table, -4 V corresponds to 1.00 and +8 V corresponds to 7.00.
