6. CALIBRATION AND ADJUSTMENTS
Functions:
F1 Calibrate pH probe
F2 Calibrate Redox probe
F3 Set point: Submenu: SET POINT PH
F4 Number of impulses per minute
F5 Timing – activating alarms
F6 Select language
F7 Regulate luminosity of screen
F8 Regulate ClF (free available chlorine) in pool
F9 Manual function – priming tests
Next to the screen there is a keyboard with 4 keys:
Enter
ENTER
F1 and F2: calibrate probes
Enter configuration menu. To do this, hold down
ENTER key for 3 seconds.
PASSWORD: press upward arrow twice, then downward
arrow twice

Shake slightly until the value of pH7 is indicated on the
screen. If after a few moments the value remains stabi-
lized and is not equal to Seven, it must be modified ma-
nually using the keys until a precise value of 7 becomes
fixed. Validate the operation by pressing ENTER.
ATTENTION:
• Clean the probe with distilled water before and
after placing it in the buffer solution.

The following function
appears: Calibrate pH probe
Press ENTER: the following
function appears: Calibrate
pH7
Then take the pH probe which
is already connected to the
instrument, remove the rubber
protection and clean the probe
with distilled water.
Insert the probe in the bottle
of buffer solution identified as
pH7 supplied with the system,
as indicated in Figure 5.
• The probes can be quickly damaged if they are not
kept in contact with liquid.

the probe with distilled water, in the same way as was
done with the pH probe.
Insert the probe in the bottle of buffer solution identified
as 475 mV supplied with the system, as indicated in
Figure 8.
The probe holder includes a flow sensor and a flow
regulation impeller. The flow sensor emits an alarm signal
if the flow is either insufficient or non-existent. When the
level alarm goes off, the system goes on stand-by. In
this way the system will only operate during the cycles
The screen displays ¨Calibrate
pH4¨. Repeat the above
operation with the pH4 buffer
solution (Figure 6). Shake
slightly until the value of pH4
is indicated on the screen. If
after a few moments the value
remains stabilized and is not
equal to 4, it must be modified
manually using the keys until
a precise value of 4 becomes
fixed. Validate the operation by
pressing ENTER.
The calibration is now comple-
ted, and the instrument informs
us of the quality and state of
conservation of the probe. The
screen displays: Probe quality
100%
This function gives information
about the state of conservation
of the pH probe. If values are
lower than 30% it is recom-
mended that the probe should
be replaced.
After calibrating the pH probe,
place the probe inside the
probe holder as indicated in
Figure 7.
Attention: Make sure the ring
seals have been put in place
correctly so as to avoid liquid
leaking.
Press the Function key and
proceed to Calibrate the Re-
dox probe. Press ENTER.
Then take the Redox probe
which is already connected
to the instrument, remove the
rubber protection and clean
