4. Maintenance

Periodic maintenance

When you must open the front cover and/or glands, make sure that the seals are clean and

correctly fitted when the unit is re-assembled in order to maintain the housing’s weatherproof

integrity against water and water vapor.
The pH measurement uses high impedance sensors (glass electrode). Keep the moisture out of

the converter inside.

CAUTION

Never use harsh chemicals or solvents. If the instrument does become heavily stained or

scratched, you may need to replace some parts. Consult Yokogawa.



Fuse

There is a circuit board mounted fuse protecting the instrument. If a fuse blows soon after the

change, contact Yokogawa.
