PROGRAMMING AND VISUALIZATION OF ON-OFF FUNCTIONING IN Rx (mV) TYPE
Rev 1.0
THIS MESSAGE MEANS THAT THE CALIBRATION IS IMPOSSIBLE AND HAS TO BE
DONE AGAIN.
If after the calibration repetition the display shows again this message:
a) Check that the buffer solution is not polluted (eventually replace it).
b) Check that the buffer solution selected on the display during the calibration is the value
of the one really used.
c) The pH probe could not be working well (replace it)
Push and quickly release CAL button and scroll the menu using + and – buttons till
the display shows "Function Type". Push CAL to enter the submenu and then, by
pressing + and – button, choice "Function On-Off" and confirm pressing CAL.
The display will show the value of setpoint stored in the last programming. Modify it
by pressing + and – button and confirm the choice pressing CAL.
The display will show the direction of dosing Oxid or Red stored in the last
programming. Choice the direction by + or – button and confirm pressing CAL.
Select Red if you want the pump to inject for mV values greater than Setpoint.
Select Oxid if you want the pump to inject for values of mV lower than Setpoint.
The display will show the % of maximum frequency (150pulses/minute) stored in
the last programming. Modify it by pressing + and – button and confirm the choice
pressing CAL. Push ESC button to esc the menu and go back in measure with the
On-Off functioning just programmed.
In the On-Off functioning if the pump is dosing the display shows "On" and the %
frequency programmed on the first row, if the pump doesn't dose the display shows
"Off" and the % frequency programmed. On the second row the display writes the
measure.

GAIN CALIBRATION
Wash 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 and quickly release CAL
button and then scroll the menu till the
display shows "Electro. Calibr." Push
CAL to enter the submenu and then the
button + to do the GAIN calibration of
the probe. If it is necessary you can
modify the value of the buffer solution
shown in the second row of the display
by buttons + or -. Push CAL to confirm.
If the display shows the message
"Imposs. Calibr." the probe calibration is
not saved. Read
paragraph named "MESSAGES FROM
THE PUMP". If no error message
appears the calibration
performed.
