Note
Even though you can calibrate the measuring range in any order, do not forget to
calibrate
the lower end of the measuring range!
Only for level electrode NRG 2.-.. :
Adjusting lower and upper end of measuring
range. The sequence is irrelevant.
Press button
to open the parameter
setting window for the level electrode.
Calibrating lower end of measuring range:
Lower water level until the lower end of the
measuring range
o
is reached.
Press button "0 %".
(actual-value output = 4 mA)
Calibrating upper end of measuring range:
Fill tank until the upper end of the measuring
range
p
is reached.
Press the green button and use the
on-screen numberpad to enter 100.
Then press button "%".
(actual-value output = 20 mA)
OR
Calibrating upper end of measuring range:
Raise water level until at least 25 % of the
measuring range is reached. Press the green
button and use the on-screen numberpad to
enter for instance "25 %". Press button "%" to
interpolate the value to 100 %
of the measuring range.
