Periodic Maintenance
Cleaning
Clean the transmitter enclosure with a soft, lint-free cloth moistened with
mild detergent.
Changing the Probe Filter
1.
Turn the filter counter-clockwise to loosen it.
2.
Remove the filter from the probe. Be careful not to touch the sensor
with the filter. Without the filter in place, the sensor is easily
damaged – handle the probe carefully.
3.
Install a new filter on the probe. When using the stainless steel
filter (for fuel cell applications), take care to tighten the filter
properly (recommended force 5 Nm).
New filters can be ordered from Vaisala, see section Spare Parts and
Accessories on page 178.
