4.1.4
Split mode The split mode divides the measuring range
into two domains:
• Domain 1 from 0 to
’Split value’
• Domain 2 from ’Split
value’ to ’URV’
(upper range value, menu3.1.2)
At digital outputs 1 or 2, it is possible to
indicate whether the current measured val‐
ue is within domain 1.
To do this, the function ’Split value active’
must be set (menu 4.2.1 and 4.3.1) Inactive
• Inactive
• Active
Split value End value of domain 1 (only when ’Split
mode = active’) URV (menu

Depends on the nominal
width (corresponding to
0.25 ... 12 m/s, <URV)
