Disable 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uid.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specied.
