Check the SWT5
1. First, check if the SWT5
requires refilling: connect it to an
SWT-MR (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 SWT5 tip
around in the air. If the tension
increases to -80 kPa within 10
seconds the T5 filling is OK.
If not then it needs to be refilled.
4. To disassemble the shaft hold
the sensor body and turn off the
shaft counter-clockwise.
