Description
1)
Set the minimum limit value for the electrode deposit
detection. When the smaller value, QE1 or QE2, is
undershot, an alarm is tripped.
Default setting: 0
Set the maximum limit value for the electrode deposit
detection. When the greater value, QE1 or QE2, is
overshot, an alarm is tripped.
Default setting: 100.000
1)
Activate the "Cond. Detection" function.
Default setting: Off
Important (Notice)
The conductivity measurement function can be
used in the nominal diameter range DN10 ... 300.
For further information read and observe chapter
"Extended diagnostic functions".
The conductivity is measured cyclically at defined
intervals. Here, a current measurement can be
started.
Display the conductivity.
The conductivity must be adjusted according to the
fluid on site. The conductivity measured with a
separate meter can be entered here.
Set the minimum limit value for the conductivity. In the
case of undershoot an alarm is tripped.
Default setting: 5 µS/cm
Set the maximum limit value for the conductivity. In
the case of overshoot an alarm is tripped.
Default setting: 20,000 µS/cm
Current impedance between electrode E1 and GND
(ground potential).
Current impedance between electrode E2 and GND
(ground potential).
Set the minimum limit value for the impedance. In the
case of undershoot an alarm is tripped.
Default setting: 0 Ω
Set the maximum limit value for the impedance. In the
case of overshoot an alarm is tripped.
Default setting: 20,000 Ω
