Calibration and Maintenance
To maintain the highest level of measurement accuracy we
recommend that the VELOPORT 20 be returned annually for
calibration.
The probe tip must be checked regularly for cleanliness. Dust and
oil on the sensor reduce the accuracy of the VELOPORT 20.
The VELOPORT 20 must be switched off for cleaning. Compressed
air or strong solvents must not be used to clean the sensor tip, as
they may damage the sensor.
To remove dust, either blow lightly on the sensor tip or wash under
lightly running water. To remove a combination of dust and oil, rinse
the sensor tip in isopropanol and then lightly blow off.
Do not touch the sensor!
