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.
