Maintenance Of The Anode And The Cathode; Replacement Of The Membrane; Instrument Setup Menu - XS Instruments OXY 7 VIO Betriebsanleitung

 Maintenance of the anode and the cathode
The sensitive part of the probe is composed by an anode and a cathode; the two elements are composed
by precious metals. Over time, these metals can be passivated by decreasing the efficiency of the probe, up
to the point that the probe does not calibrate.
In this case, remove the membrane and the passivation with very fine abrasive paper, gently scratching the
metal parts; wash everything with distilled water and proceed with the Replacement of Electrolyte.
Perform the Calibration of the sensor. If it does not work, proceed with the Replacement of the membrane.
 Replacement of the membrane
If the membrane has ripples or irregularities, it must be replaced with a new one.
Remove the membrane cap and replace it with a new and intact one.
With the new membrane, follow the procedure of the Replacement of Electrolyte.
If, even after these procedures, the probe does not calibrate, replace the probe.
