CHAPTER 5
MAINTENANCE
This chapter contains information that is needed in basic maintenance of
the product.
Periodic Maintenance
Cleaning
Clean the probe with a soft, lint-free cloth moistened with mild detergent.
Changing the Probe Filter
In the course of time the probe filter will be contaminated with matter
that you cannot remove by cleaning. When this happens, the HMP155
response time becomes longer and measurement accuracy decreases. You
need to replace the probe filter with a new one:
1.
Remove the filter from the probe.
2.
After removing the filter, check the O-ring and change it if
necessary. See Figure 12 on page 53.
3.
Install a new filter on the probe.
New filters can be ordered from Vaisala, see section Options and
Accessories on page 77.
