HC151+ pH(Rx)-Cl(J) / HC200+ pH(Rx)
ENGLISH
Chlorine probe calibration (HC151 + only)
For a correct calibration follow the steps described below:
To calibrate the Chlorine probe it is
necessary to have a photometer and a
DPD test kit.
Connect the 4-pole connector of the
probe to the relative input on the bottom
of the pump (refer to the drawing on
paragraph 5 to identify its position);
Install the probe inside the modular
probe holder and regulate the flow of
water with a constant flow rate of not
more than 60 l / h and not less than
30 l / h;
Wait for the polarization of the probe
(this can also take several hours: from 1
to 24), the probe manufacturer suggests
to wait up to 6 hours before performing
the calibration;
ATTENTION: if the Pt-Cu probe is
used to determine the free chlorine,
the polarization times are reduced to
about 1 hour.
Access the Calibration menu and follow
the instructions on the display: take a
water sample and use the DPD test kit
and photometer to determine the
Chlorine value, modify the value read on
the pump display with the value detected
by the photometer. Press on the
encoder to confirm this value;
ATTENTION: for the membrane
chlorine probe (ppm-mV or ppm-mA)
follow the probe manufacturer's
instructions for the mandatory
preliminary operations before being
able to connect it to the pump;
