When replacing the filter, note the following:

- Touching the filter with your fingers will also deposit oil and dirt on

the filter, which may affect the measurement. Always handle the filter

with gloved hands.

- When installing the transmitter after a filter change, inspect the

sealing ring first. Use a new one if the old ring is visibly damaged.
