VC63A Vibration Meter 0~1000um Pocket-Sized Instrument For
Measuring Mechanical Vibration Displacement And Intensity
This vibration meter is a pocket-sized instrument for measuring
mechanical vibration displacement and intensity. which is suitable
for inspection of various mechanical vibration in power, petroleum,
chemical, metallurgical and other industrial departments.
FUNCTION CHARACTER
1. Just need to connect to the sensor, it will finish a completely
testing system.
2. Use P-P value to express the vibration displacement value.
3. Use RMS to express the vibration speed value.
4. 3 1/2 LCD display.
5. Use 9V battery, and have low battery indication function.
SPECIFICATION
1. Measurement range: vibration displacement:0 ～1000μm(peak to
peak)
velocity:0～71mm/s (RMS)
2. Frequency response and error:
vibration displacement( P-P ):12～200Hz,≤±10%
velocity( RMS ):12～500Hz,≤±10%
3. Linearity and Accuracy
vibration displacement( P-P ):0～20μm,≤±10% ＞20μm, ≤±5%
Velocity: 0～2.0mm/s, ≤±10% ＞2.0mm/s, ≤±5%
4. Low voltage indication: When the battery voltage is below 6.5V,
the screen will prompt low voltage, then you should replace the
battery with a new one.
5. Environmental: Environment temperature : 0 ～ 40 ℃ relative
humidity: ≤ 80%
atmospheric pressure : 75 ～ 106kpa
6．overall dimensions:185(H)×68(W)×30(D)mm
7.Weight: 480g(including battery)
WORKING PRINCIPLE
Vibration signals collected by magnetoelectricity speed sensor are
processed by low frequency compensation, amplification, active
integration, peak-peak detection, RMS operation and differential
amplification circuit, then they are processed by analog-to-digital
converter. Finally, the vibration values are displayed by LCD.
OPERATION
1. Loading battery
Open the battery cover, pay attention to the polarity of the
battery, then put a 9V battery inside the battery box, and close
the battery cover.
2. Checking Battery Voltage
Select the velocity or displacement function, if you can see the
low battery symbol on the left of the LCD, then you need to change
a new battery. If there’s no such symbol on the LCD,it means the
voltage is enough for testing.
3. Setting Measurement Mode
Select the velocity or displacement measurement mode with the mode
selector. The selected mode is indicated by the arrow on the right
of the display.
4. Measurement
Connect the signal line to the input sensor terminal, select the
measuring mode to start your test. Hold the sensor by your hand in
one direction(vertical or horizontal), do not move, and you can get
the value when the sensor is synchronized with the vibration.
NOTICE
1. Sensors are important elastic sensitive devices, improper use
and storage will affect the accuracy of measurement and strictly
prevent collision.
2. Instruments may not be displayed due to damage or poor contact
of sensor signal lines. Conductor condition should be checked
frequently.
3. The sensor core is fully enclosed and can not be disassembled,
but the components connected with the output wire can be
disassembled and re-welded.
4. Instrument is not used for a long time. Please take out the
battery to avoid instrument corrosion.
