ON-OFF:
pH ELECTRODE CALIBRATION
Attention, be sure that the buffer solutions used in calibration matches always the indicated value, and that they're not
polluted.
If it is necessary you can modify the value of the buffer solution shown in the second line of the display using the buttons
+ or -. Push CAL to confirm.If you read the message "Calibration Impossible" the probe calibration is not saved. Read the
following paragraph named "DUAL MESSAGES". If no error message appears the calibration has been made.

ON-OFF OPERATION MODE:
CONSTANT DOSAGE WHICH ACTIVATES
WHEN THE MEASURE MOVES AWAY FROM
THE SETPOINT
Setpoint = measured value that you wish to have
in the system
Hysteresis = range of the measured values
centered over the Setpoint where DUAL does not
modify its operation
Regulation Acid (pH -) = dosage for measured
values greater than Setpoint
Regulation Alkaline (pH+) = dosage for
measured values lower than the Setpoint
Flowrate % = dosing flowrate

OFFSET CALIBRATION
Dip the probe in the pH7 buffer solution and
wait for the stabilization of the measure on
the display. Push CAL 3 times and then
scroll the menu by + and – buttons till the
display shows "pH Electrode Calibration".
Push CAL to enter the submenu and then
the button – to do the OFFSET calibration of
the probe. If it is necessary you can modify
the value of the buffer solution shown in the
second line of the display using the buttons
+ or -. Push CAL to confirm.
If you read the message "Calibration
Impossible" the probe calibration is not
saved. Read the following paragraph named
"DUAL MESSAGES". If no error message
appears the calibration has been made.
GAIN CALIBRATION
Clean the probe with water and then dip it in
9 pH or 4 pH buffer solution. Wait for
stabilization of the measure on the display.
Push CAL 3 times and then scroll the menu
by + and – buttons till the display shows "pH
Electrode Calibration". Push CAL to enter
the submenu and then the button + to do the
GAIN calibration of the probe.
