START-UP
At start-up the microcontroller displays for a couple of seconds information about the firmware
(type / version), then shows the two measures flashing for all the start-up delay time (if set) and then
starts operating accordingly with the configured working mode.
DISPLAY
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 AAN 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:
•
“Pomp 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.
