During the programming if you do not push any button (+,-, CAL) for more than 60 seconds, the pump will
get out of programming keeping the data stored until that moment.
CHLORINE PROBE CALIBRATION
Attention,
It will be necessary to do a comparative free chlorine test (for example a DPD1 photometric test)
Zero Calibration is executed at factory and then go directly to RECOMMENDATIONS paragraph.
The pump is been projected so that the electrical zero probe calibration is equal to electrochemical zero calibration.
So if it's really necessary to calibrate the zero of the probe read the following instructions:
-disconnect the chlorine probe input from the pump
1)wait until the display reaches a stable reading(any value)
Push and quickly release CAL button and then scroll the menu by + and – buttons till the display shows "Electro.
Calibr." 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 shown in the second row of the display by buttons + or – till 0.00ppM reading.
Push CAL to confirm. If the display shows the message "Imposs. Calibr." the probe calibration is not saved. If no
error message appears the calibration has been performed.
Do a DPD1 test on the water sample taken from the Tap of the probe holder. 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 shown in the second row
of the display by buttons + or - till the value is equal to that of DPD1 tester. Push CAL to confirm.
If the display shows the message "Imposs. Calibr." the probe calibration is not saved. Read the following paragraph
named "MESSAGES FROM THE PUMP". If no error message appears the calibration has been performed.

RECOMMENDATIONS: before doing
GAIN calibration, PAY ATTENTION TO
THE FOLLOWING INSTRUCTIONS:
1) it is necessary to stabilize the water
flow by turning the knob regulation till
the floater stays in the upper position
(60l/h). This is important because the
right water flow rate allows the glass
spheres to clean adequately the cupper
surface.
2) Before calibrating the GAIN of the
chlorine probe, stabilize the pH at the
working conditions.(We recommend to
choose a value from 7.0 to 7.3pH) .
3) It is necessary to do the Chlorine
gain calibration at concentration values
nearest possible to the desired setpoint.
For
example
if
concentration desired is 1.20ppM it is
strictly recommended to do the gain
calibration
with
water
conditions. Use a DPD1 photometric
test
to
check
concentration in the water sample
taken from the Tap (see the figure on
the left)
GAIN CALIBRATION
It is recommended to do the gain
calibration after at least 2 or 3 hours
of optimal working conditions, or
alternatively it is possible to do a
first gain calibration after having
installed the pump and the probe in
the plant and then do the definite
calibration after 24 hours of work of
the probe. After having stabilized the
flow and the pH and having stabilized
the
chlorine
concentration
optimal and desired value, wait for the
stabilization of the reading on the
display.
