Disable
Does not use the electrode adhesion detecting function.
Enable
Enable
Uses the electrode adhesion detecting function.
NOTE
If the electrode adhesion detecting function is not used, the electrode resistance value and level
are cleared.
NOTE
Before using the electrode adhesion detecting function, be sure to make sure that the sensor is in
the full pipe state. If the sensor is in the empty pipe state, the function to detect adhesion may not
run normally.
NOTE
The electrode adhesion detecting function is restricted by the conductivity of fluid. The
recommended conductivities are as follows.
Meter size
Conductivity
2.5 to 10 mm
30 μS/cm or larger
15 to 400 mm (0.5 to 16 in.)
10 μS/cm or larger
500 mm
20 μS/cm or larger
NOTE
If the data update cycle for the adhesion detection is shortened, the error of the electrode
resistance value increases. Do not change the default value unless especially specified.
