CONTENTS
1.1 . BASIC WORKING PRINCIPLE
TV300 uses piezoelectric acceleration transducer to convert vibration signal into electric
signal. Then by analyzing input signal, results including RMS of velocity values, peak-
peak value of displacement, peak values of acceleration or real-time spectral charts are
displayed or printed out.
1.2. APPLICATION RANGE
The vibration meter is designed to test conventional vibration, especially the vibration
test in rotating and reciprocating machines. It can be used not only to test the
acceleration, velocity, and displacement of vibration as well as rev (or inherent
frequency), but also perform simple failure diagnosis.
The technical specifications of TV300 comply with the requirements of GB 13823.3.
TV300 is widely used in machinery, power, metallurgy, automobile and other industrial
fields.

Manual TV-300 3
1. Vibration:
A rapid linear motion of object about an equilibrium position, like piston, tuning fork
or motor.
2. Vibration displacement:
The magnitude of a vector from the initial position to a subsequent position assumed
by a body.
3. Vibration velocity:
The rate of speed of vibration.
4. Vibration acceleration:
The rate of change of vibration velocity with respect to time.
5. Vibration frequency:
The number of complete cycles of vibration per unit time.
6. Point number:
One point number correspond to one testing point, TV300 will keep up to 62 historical
results for each point.
7. Patrol test:
Test more than one point in a fixed routine. Each point correspond one testing point.
8. Warning limit:
Remind users that the vibration is beyond the limit of the safe state.
9. Alarming limit:
Remind users that the vibration is beyond the limit of the destruct status.
10. RMS, peak values and peak-peak values (see Figure 2-1)
11. Spectral chart:
A chart indicates the magnitude distribution of each frequency in the whole vibration.

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 he object
to be tested.
- The transducers should be in close contact with the object to be tested.
4.2. INSTALL METHOD
Install method/ Install with Install with Install with
Contrast bolts magnetic base probe
Cost None low Rather high
Affection on None When roughness is When caring about
the result worse than Ra1.6, acceleration and the
the result maybe vibration frequency is
not stable. higher than 1KHz, the
result will be smaller.
Convenience Not good good Best
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
transducer to the object by bolts (see Figure 4-1). And this is the method that the
frequency response is best.

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.
Figure 4-2
4.2.3.INSTALLED 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)

5.1. BASIC CONCEPT
Special display mode is as follows (see Figure 5-1).
Figure 5-1
- Battery status: The full scale indicates the power is 100%.
- Working status: When the measurement goes on, displays one moving column.
When the measurement is finished, displays "at hh : mm".
- Time: Current time.
- Measurement point number: One point number correspond to one testing point,
TV300 will keep up to 62 historical results for each point.
- Measurement values: Indicate the testing results of the acceleration, velocity, and
displacement.
- Status Bar: Indicate the relative relation of testing result, last testing result, warning
limit and alarm limit.
- Main menu: Consist of display, analyse, view and system.
5.2. SIMPLE TEST
- Press “on/off” key to power on;
Press “MEAS” key to start the testing operation (displays one moving column);
Press “MEAS” key again to finish the test;
Read the measurement values
- When testing continuously, the measurement point number can increase
automatically. Users can also choose the measurement point number by Up/Down
keys.
