12. Switch everything off and short-circuit the ozone sensor wires.
13. Put the ozone sensor back to the flight box and store it in a dark,
clean-air environment at a temperature of 20 ... 25 °C until it is
used.
After these preparations, a sensor cleaning process takes place, whereby
both half cells (anode and cathode) and ionbridge get in balance.
