Sintered Steel Filter
Check the sintered filter of the probe regularly. A dirty or corroded filter
needs to be replaced, as it may increase the response time and decrease
the lifetime of the sensor. Make also sure the filter remains tighly fit.
If you need to replace the filter:
1.
Make sure you have the spare part available, or order one from
your nearest Vaisala Service Center. See section
for contact information.
2.
Carefully remove the old filter from the probe.
3.
Install the new filter to the probe. Make sure to tighten it.
CAUTION
Avoid touching the sensor element, as this may lead to physical
damage to the component, or measurement inaccuracy due to sensor
contamination.
