Service and maintenance
Check the T5
1. First, check if the T5 requires
a refilling: connect it to an
Infield7 or a voltmeter and
power supply.
2. Wrap a dry paper towel
(kitchen roll) around the cup to
dry the ceramic surface.
With short shaft lengths cover
the ceramic with a paper
towel to avoid contamination.
3. Now wave the T5 tip around
in the air. If the reading will rise
to -80 kPa within 10 seconds the
T5 filling is ok.
If this is not the case the T5
needs to be refilled.
4. To disassemble the shaft hold
the sensor body and turn off the
shaft counter-clockwise.
