Time TV-300 - Installed with Magnetic Base; Installed with Probe

4.2.2. INSTALLED WITH MAGNETIC BASE
Application range: Magnetic, flat surface, roughness less than Ra1.6, acceleration
less than 20 m/s2.
Usage: Before usage, take off the iron wafer and rubber wafer under magnetic
base (ensure enough suction), and then screw up the magnetic base on transducer
(see Figure 4-2). After usage, put back the iron wafer and rubber wafer to maintain
the magnetism.

4.2.3.I
NSTALLED WITH PROBE
Applications range: Frequency is less than 1KHz; vibration energy is not too small.
Usage: Connect the needle to the transducer directly by using probe groupware
(see figure 4-3)
