Maintenance
6.4 Scheduled maintenance
lists items, except the electrode, that need to be maintained
by service personnel ONLY. Contact the manufacturer for more
information.
6.5 Replace the membrane cap, electrolyte and electrode
Important Note:
Never lubricate the membrane cap or the
electrode with grease, silicone oil or Vaseline. This will cause
damage to the Teflon membrane which will cause poor
performance.
Note:
The service life of the Teflon membrane will be reduced by tensides
or organic solvents in the waste water.
For optimal performace, replace the the membrane cap, electrolyte
and electrode regularly (refer to
).
While operating the instrument, the amount of electrolyte should be
between 4 mL and 11 mL. With less amount of electrolyte, the
accuracy will be reduced for low measured values in the related
measuring range. To determine how much electrolyte remains in
the electrode body, refer to
.
