4.2.2 Installed With Magnetic Base
Application range: Magnetic, flat surface, roughness less than Ra1.6,
acceleration less than 20m/ .
Usage: connect the vibration sensor with magnetic base with the M5 bolt
included. And then place the magnetic base to the object to be tested. Please
refer the below.

The surface is slick and flat
4.2.3 Installed With Probe
Applications Range: Frequency is less than 1KHz and vibration energy is not
small. Usage: Connect the needle to the sensor directly by using probe
groupware.(see Figure 4.4)
