6.2.9 Signal output
The signal o
utput supplies a load-independent current of 0/4 –20 mA that corresponds to a
conductivity of 0 to 100% of the selected measuring range.
Four different measuring ranges can be selected under MEASURING RANGE in the
CONFIGURATION FUNCTIONS menu (selected with ▲▼ keys)
10 mS/cm = 20 mA
20 mS/cm = 20 mA
100 mS/cm = 20 mA
200 mS/cm = 20 mA
0..20 mA or 4..20 mA can be selected (selectable with ↵ key, active setting is highlighted)
under CURRENT OUTPUT in the CONFIGURATION FUNCTIONS menu.
