VISUALIZATIONS
During normal operations, the display shows the two measured values on the top line, while the bottom row displays the
status of the two pumps. In models with Pt100 (optional) the bottom row switches between the temperature measurement
and the status of the two pumps.
For example: “7.25pH 286mV”
“P1 ON P2 020%”
(pump 1 ON in ON/OFF mode, pump 2 ON in proportional mode with indication of the
functioning percentage)
In these conditions, pressing the ⇓ or ⇑ button, you can display the OFFSET and GAIN values of the pH and redox
measurements.
For example: “7.25pH”
“O=-4 G=1.000”
This information is useful to verify the electrode status. Note that an electrode in good condition should have an offset close
to zero and a gain close to 1.000. When these values deviate from the ideal ones, indicate a dead electrode or sensor aging.
During manual working mode, the display shows on the top line the pump to which the information refers, while the bottom
row shows the pump status.
For example: “Pump 2 manual”
“ON”
In these conditions, pressing the ON/OFF button allows to enable/disable the pump.
In case of fault or alarm condition, the pump stops dosing until the normal working conditions are restored.
OPERATION OF THE ELECTRONIC UNIT
To access the configuration, calibration and manual mode menus, press the CAL button. The display will show the following
available options:
• Standard Configuration
• Advanced Configuration
• Calibration IN1 (input 1) pH
• Calibration IN2 (input 2) redox
• Manual Mode 1 (pump 1, acid dosage)
• Manual Mode 2 (pump 2, chlorine dosage)
Use the ⇓ / ⇑ keys to scroll the available options, then press CAL to enter the highlighted mode or ESC to return to
measurement visualization.
For a complete list of parameters, valid values and related explanations, see the “List of Configuration Parameters”
section.
Standard Configuration
The standard configuration mode allows the customer to set a series of parameters related to the normal functioning of the
unit. These parameter can be freely accessed and configured from the front keyboard.
1) Once selected the “Standard Configuration” option, press the
CAL button to edit the list of parameters, or press ESC to
return to the normal visualization mode.
2) Now use the ⇑ and ⇓ keys to scroll the list of the available
parameters.
3) To modify the displayed parameter, press CAL; to quit the
mode press ESC.
