4.1 Installation Principle
The testing position should show the vibration characters of the object to be
tested.
The main axis of the transducers should be consistent with the direction of
the object to be tested
The sensor should be in close contact with the object to be tested.

4.2.1 Installed With Bolt
Application range: Screw eye has no influence on the running of the object
being tested. Usage: Drill a screw eye 5mm deep in the object being tested.
Connect the sensor to the object by bolts (see Figure 4.2). And this is the
method that the frequency response is best.
