Redox probe calibration
For proper calibration follow the steps described below:
To calibrate the Redox electrode it is
necessary to have a buffer solution with
a known value (for this example the
475mV solution was used).
Connect the BNC connector of the
electrode to the relative input on the
bottom of the pump (refer to the drawing
on paragraph 5 to identify its position);
Remove the protective cap of the
electrode then wash it with water and dry
it;
Enter in Calibration menu and follow the
instructions on the display: dip the
electrode in the 475mV buffer solution,
wait for the measurement to stabilize, if
necessary, modify the value read on the
display with the one on the solution (it
may happen that the measurement does
not correspond perfectly to solution, this
is perfectly normal). Press on the
encoder to confirm this value;
At the end of the procedure, the quality
of the electrode will be shown on the
display.
For values between 25% and 0% we
suggest replacing the electrode.
