MANUALE D'INSTALLAZIONE E USO
A AMPEROMETRIC 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
-wait until the display reaches a stable reading (any value)
Push and quickly release CAL button 2 times and then push + button and confirm by CAL. Scroll the menu by + and
– buttons till the display shows "Cl 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 shown in the second row of the display
by buttons + or – till 0.00ppM reading. Push CAL to confirm.

RECOMMENDATIONS:
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
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
values nearest possible to the desired
setpoint. For example if the chlorine
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)
