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.

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.

5.4. DESCRIPTION OF FUNCTIONS
5.4.1. DISPLAY
"Display" can change the display modes from common, special and spectrum
modes. It can give convenience for users to look through the data from different
way, but it does not change the default settings of display modes. If users want to
change the default settings of display modes, the submenu "Display modes" in the
menu "System" should be changed.
5.4.2. ANALYSE
When diagnosing the fault, users could use this function. Spectrum chart maybe
display like this. (See Figure 5-2)
Figure 5-2
When the measurement value is higher than the warning limit, TV300 can
automatically give an alarm and request to enter into spectrum testing mode (see
Figure 5-3).

The "Analyse" menu consists of "Print", "Auto", "Adjust" and "Zoom" four sub items.
- Print: Print out current spectral charts.
- Auto:
Peak values of the spectral chart could be automatically captured. And different
peak values could be selected by Left/Right keys. (see Figure 5-4)
Figure 5-4 A B
Figure (a) shows the peak-peak value tested is 62.6Hz, that maybe the rev of the
tested object;
Figure (b) shows the peak value tested is 109.6Hz, that maybe the inherent
frequency of the tested object;
- Manual
The values of different points in the charts can be looked through in the manual
style. The cursor position can be adjusted by Left/Right keys. The amplitude and
frequency of the point, which the cursor indicates, can be displayed.
(see Figure 5-5).
Figure 5-5
- Zoom
In spectrum analysis, the spectrum zoom function can change the frequency
resolution in the range selected by users. Firstly, to select the range of the
frequency----that is the concerned area, press Left/Right keys to move the
cursor. The cursor could move more quickly when the Left or Right key is hold.
Secondly, Up/Down keys could change the frequency resolution. The resolution
could reach 0.25Hz.

5.4.3. VIEW
Users can look through the measurement results stored in the memory by selecting
"View". The information of each measurement result comprises point number,
testing time and certain results (see Figure 5-7). Users could print out the list. Also,
the data can be deleted.
Figure 5-7
5.4.4. SYSTEM
5.4.4.1. Measurement settings
- Parameter: Velocity, Displacement and Acceleration. Affection of this
setting is shown in 5.4.4.3.
- Transmission bands: According to application, select the bands of frequency.
- Limit: When the limit is set, the meter could display status bar to
inspect the status of the running equipment easily. As
soon as the tested value is beyond the limit, the meter
request to enter into diagnosis (see Figure 5-2).
5.4.4.2. Point increment
If select "Yes", when a testing operation of the current point number is
finished, the point number will increase automatically, and go into the
waiting state of the next point number. Up/Down keys can also change
the testing point number.
If select "No", point number will not increase automatically. When tests
are performed continuously, the measurement results will be regarded
as different testing results of the same testing point number.
5.4.4.3. Display modes
There are three display modes: Common mode (Table 5-1, Figure 5-8),
Special mode (Table 5-2, Figure 5-9) and Spectrum mode (Figure 5-2).

5.4.4.4. Personal settings
- Languages:
There are two languages available: Chinese and English.
- Auto shutdown:
The meter will shutdown automatically if there is no operation for a
while. And users can set the delay time themselves.
- LCD contrast:
Users can adjust LCD contrast by Left/Right keys.
5.4.4.5. Time
Time is the assistant information of the measurement results. TV300 can
automatically record the time when the test is performed. If the time is
not correct, it should be reset manually.
5.4.4.6. Software information
It consists of the model of the meter and the software identifier.
14 Manual TV-300

TV300 has accessories such as printer and corresponding software. If equipped with
printer, the printing operation can be performed. The data stored in TV300 can be
uploading to PC and do analysis with corresponding software. If PC is equipped with
printer, the data can also be printed out from PC.
TV300 connects to printer or PC through a communication cable. One end is connected
to TV300 through RS232 serial port, and the other end is connected to printer or PC
through a 9-pin connector.
How to use the software can refer to the specifications of the corresponding software.
Manual TV-300 15
6HOW TO USE THE ACCESSORIES

- When the battery cannot charge, check the charging indicating light.
- The measurement value is unstable.
1. Make sure the vibration frequency of the vibration object is in the frequency
range of 10Hz-10kHz.
2. If the magnetic base is used, pay attention to:
a. Make sure the surface of the tested object is flat, and roughness is smaller
than Ra1.6.
b. Make sure the iron wafer below the magnetic base is taken off, and the
magnetic force is enough.
- When enter the non-mother language system because of incorrect operation, users
can change back the mother language referring to the construction of the menu
(see 5.3).
If some trouble cannot be overcome, please contact to TIME Group Inc.

7TROUBLE SHOOTING

1. Operating environment: Strictly avoid collision, heavy dust, dampness, strong
magnetic field, oil, grease and dirt.
2. How to clean the main body of the meter: Because alcohol and other chemical
liquid can erode the main body of TV300, especial the display window, little water
can be used to clean to meter smoothly.
3. How to use the connector: Don't plug the connector of the transducers, printer or
PC, when TV300 is power on.
4. Calibration: The vibration meter is a high-precision instrument and the environment
will influence on it. So it should be calibrated periodically (half a year or one year). If
the sensitivity has changed, it can be adjusted by rotating the knob which is use to
adjust the sensitivity.

A. RANK OF MACHINE VIBRATION (ISO2372)
Note:
(1) Class I is small motor (power less than 15kW). Class I is medium motor (power
between 15kW~75kW). Class ? is high power motor (hard base); Class ? is high power motor (stretch base).
(2) A, B, C, D are vibration rank. "A" means good, "B" means satisfying, "C" means not satisfying, "D" means
forbidden. Vibration velocity should be taken from the three perpendicular axes on the motor shell.
