Measuring range type 1 (mr i < mr (i+1))
The full-scale value of measuring range (i) must be lower than the full-scale value of the
subsequent measuring range (i+1). The following switchover points are used:
So
H
High switchover point (= full-scale value
minus 10 % of the span)
So
L
Low switchover point (= full-scale value
minus 20 % of the span)
FSV
Full-scale value
SSV
Start-of-scale value
When the high switchover point of a measuring range is exceeded, there will be a switch to
the next-higher measuring range. If the measured value is lower than the low switchover
point of the next-lower measuring range, the device switches to the lower measuring range.
Measuring range type 2 (mr i ≥ mr (i+1))
The full-scale value of measuring range (i) must be greater than or equal to the full-scale
value of the following measuring range (i+1). Because the spans get bigger, the
corresponding start-of-scale values get smaller. The following switchover points are used:
So
H
High switchover point (= start value of
measuring range)
So
L
Low switchover point (= start value plus
10% of the span)
FSV
Full-scale value
SSV
Start-of-scale value
When the high switchover point is violated, there will be a switch to the next-higher
measuring range. If the measured value violates the low switchover point of the next-lower
measuring range, the device switches to the lower measuring range.

Setting the measuring ranges
Note
Component-specific setup
Measuring ranges are component
-specific.
Repeat the procedure described below for all the components, if necessary.
