Indication of Water Quality
Selection of either electrode for ion-exchanged or distilled water
Each one push on SELECT switch selects alternatively the electrode of either water
quality examiner to be measured.
Among the operation panel indicators;
● Either ION EXCHANGED WATER and DISTILLED
WATER is lit alternatively by each push to identify one
electrode measured.
(The electric conductivity is shown by the unit of
“ ” when the power switch is “ON”.)
Change of the unit to indicate water quality.
1. Each one push on the FUNCTION key changes displays of indicator (2).
Operation panel display
●The indicator (2) changes its displays as follows.
Repeated collection
Mode to display the total water flow
Mode to change the unit to indicate water quality
Select the display of .
2. Push either ▲ ▲ ▲ ▲ or ▼ ▼ ▼ ▼ key once.
Among the operation panel indicators;
● The unit for water quality indication changes. Then the
unit of resistivity “
” is shown.
● The indicator (1) also indicates the resistivity. The
integral number shows from 1 to 18 within the range of
1.0 to 18.2 (
).
3. Push the ENTER key, Then, you can fix the unit and get out from the function mode.
Among the operation panel indicators;
●The indicator (2) shows .
（ The unit to indicate water quality returns to the electric
conductivity when you switch the POWER key OFF and
ON again.
