Completing sensor installation
Complete the following in the ET210 installation app software on the
Installation tab:
Procedure
1. Press the Start button. Wait for an Ultrasonic waveform to download
from the sensor.
Note
Waveforms are automatically downloaded every 10 seconds. When a
new waveform arrives, the lines briefly become thicker.
2. Check the quality of the waveform. The first one or two reflections
must be well defined above the noise in the signal. Only one
reflection is needed to calculate a thickness. If the signal is poor,
move the sensor to a slightly different position.
3. Check the measured thickness displayed is inline with expectations.
4. Tighten the strap using the tensioning tool provided so that the
rubber shoe is compressed slightly and the sensor is held in place
securely. On small diameter pipes the curved part of the shoe should
touch the pipe. Overtightening the strap will deform the shoe and
could damage the sensor.
Note
For the same tension in the strap, more force is exerted on the shoe
on smaller diameter pipes.
Correct strap tension
Strap too loose; shoe
not compressed
Strap too tight; shoe
too compressed
5. Wait for a new waveform to display and check the ultrasonic
waveform quality is still good after tightening the strap
6. Press the Complete button. Verify that the Install State is Off and
Installed is ticked in the footer of the application.
7. Remove the CC21 and fit the power module, tightening the two
power module retaining bolts. When the power module is fitted, the
sensor will restart and try to join the
