Function of the third electrode
The instrument is equipped with a sensing electrode as standard, which is located in the upper part of the measuring tube
section, and is used to indicate flooding of the measuring tube section by liquid.
This third electrode can work in three modes.
a) If the measuring tube section is empty or not entirely flooded, i.e., the electrode is not in contact with liquid,
measurement is locked and instrument displays zero flow rate. At the same time, character Z is displayed in the lower-left
corner of the display indicating that the lock function has been enabled.
1. Select the
MEASUREMENT
option from the main menu and confirm your selection by pressing the
EXE
button. A sub-menu will be displayed.
2. Select the

command under the option

in order to activate the above described function.
NOTE:
The above described function is set by default in the factory and does not need to be set in most cases.
b) If the measuring tube section is empty or not entirely flooded, i.e., the electrode is not in contact with the liquid,
measurement is not locked and this situation is only indicated. The instrument displays flow rate and, at the same time,
character Z is displayed in the lower-left corner of the display to indicate that this function has been enabled.
1. Select the
MEASUREMENT
option from the main menu and confirm your selection by pressing the
