7 Operation Method
When the instrument is powered on, the “POWER” lamp will be lightened, and the nixie tube will
display the conductivity value. Switch on ECS to start water producing, stand by in the nixie tube if it is not
switched on.
A Press key, the nixie tube indicates “1.000” (electrode constant). Press key again and
again, the following menu items will come out:
Electrode constant: this value is keyed in by the manufacturer at ex-factory, it should not be
modified at will. In case of replacement of electrode, please enter it under the
direction of the manufacturer.
Conductivity limit value: the default value is “100.0” (operation limit).
Flush time at start-up: “A-005” “005” is the default value, the unit is “second”, and the setting
range is 0~249s. If the setting is “90”, then the membrane will be
flushed for 90s in each time the system start up to produce water.
Flush time at water level: “B-005” “005” is the default value, the unit is “second”, and the
setting range is 0~249s. If the setting is “90”, then in each time that
the pure water tank is full and the system stops, or the system
restart after low water level is detected, the membrane will be
flushed for 90s.
Flush interval: “C-03” “03” is the default value, the unit is “hour”, and the setting range is 0~99h.
If the setting is “03”, then the membrane will be flushed once at
every 3 hours of continuous water producing or standing by status.
If you are not satisfied with the above mentioned parameter settings, you can modify them by ,
and keys. When the data modification is finished, press key to save the data and go back to
measuring status (if you don’t press this key, the system will automatically go back to measuring status
after 3 minutes, but the data modification will not be saved.)
