NOTE: Perform a calibration after one hour running-in time and, if required,
after 24 hours. you must calibrate each time the cell sand is replaced.
The calibration must be checked after one day. Note the electrolyte’s
expiration date. We recommend replacing the cell sand when replacing
the electrodes and porous membranes.
