With the settings above:
- If the pH measure is lower than 7.20pH, Relay 1 is always OFF (open).
- If the pH measure is greater than 8.20pH Relay 1 is always ON (closed).
- If the pH measure is between 7.20pH and 8.20pH Relay 1 is ON for a number of seconds proportional to the distance of
the measure from the Setpoint 7.20pH.
-For example, if the measure is 7.70pH Relay 1 will be OFF for 165 seconds and ON for 195 seconds.
-If the pH value decreases to 7.40pH, Relay 1 will be ON for 96 seconds and OFF for 264 seconds.

With the settings above:
- If the RX measure is greater than 730mV, Relay 2 is always OFF (open).
- If the RX measure is lower than 630mV Relay 2 is always ON (closed).
- If the RX measure is between 630mV and 730mV Relay 2 is ON for a number of seconds proportional to the distance of
the measure from the Setpoint 730mV.
-For example, if the measure is 680mV Relay 2 will be OFF for 165 seconds and ON for 195 seconds.
-If the RX value decreases to 710mV, Relay 2 will be ON for 96 seconds and OFF for 264 seconds.

With the above settings the instrument will maintain the Relay1 off (open) until the measure will be between 6.50pH and
7.60pH. Outside these thresholds the Relay 1 is on (closed).
There is the possibility to programm a delay of activation and a delay of deactivation of the relay 1. In the above example
they are programmed with a value of 5 seconds.
To change the settings, press Enter and edit the parameters one by one using
