Overview

VC-02 vibration calibrator consists of the standard sensor, signal generators, power amplifiers, signal conditioning and digital control display circuit with a small, solid and stable structure. It is a full-functions vibration calibrator for industrial field or laboratory; High precision, simple operation, easy to use. It can calibrate a variety of types of vibration sensors such as acceleration sensors, magnetic velocity sensors and eddy displacement sensors, and calibrate some vibration monitoring systems and data acquisition system.

8. Maximum Vibration Amplitude & Maximum Load
   For the VC-02 is small, so the calibration of the different sensors at different frequencies (different weight), the calibrator can output amplitude is not the same. The maximum vibration amplitude and the maximum load at a certain frequency, is as follows: All values

are RMS.

Operation Steps

1. Mounting Sensor
   

2. Sensor (Acceleration or Velocity ) installation: put the M5 screw, sensor fixed on the table in turn. Different sensors, sometimes need to use the corresponding conversion screw;

3. The eddy sensor installation: Put the benchmark on the test plate, the eddy sensor fixed suite in sequence;

4. When calibrating, place the calibrator stable as possible. When change the sensor, need to turn off the power supply. After the calibration, the sensor should be removed for avoiding the sensor is left for a long time on the table.

5. Cable Connection

6. The calibrator can measure and display the value of measured sensor output , so the output of these sensor such as charge mode ,IEPE mode and Voltage mode can be connected to the socket of signal input socket(BNC);

7. For the output of 4-20 mA sensor, please connect the signal to “4-20 mA” terminal, internal calibration instrument is illustrated below.

8. For eddy displacement sensor, the calibrator can offer the power to the preamplifier; The green terminal is -24VDC, the black one is 0V; And the output of preamplifier connect to the signal socket of the BNC ;

9. If hope to measure the output signal of adjusted sensor, please check the socket of sensor output signal­(BNC); For this signal can be adjusted automatic by the calibrator, so the output signal should be amplified X1 or X10.

10. Connect to AC Power: Please confirm the AC power supply should be 220 V / 50 Hz;

11. If hope to operate by PC, connect the calibrator to PC by one USB cable.

12. Operation Setting
    After checking cables and sensors be fixed correctly, turn on the power and the LCD will display as follows:

13. Sensor Type can select the type of tested sensor such as Acceleration, Velocity and Displacement. Input Type: select the input type of tested sensor such as PE(Charge Mode),IEPE Mode ,Voltage Mode and 4-20mA output Mode.
    Setting Method: Press the knob can change or <Input
    Type>and counter clockwise or clockwise this knob of current location. can change the types

14. Vibration Freq: Vibration Frequency adjustment
    Setting Method: Press the knob to change the cursor position; counter clockwise or clockwise adjust this knob , set the frequency ;
    Vibration Amp: Vibration Amplitude adjustment
    Setting method: Turn this knob counter clockwise, can be reduced vibration amplitude; And Turn this knob clockwise, can add vibration amplitude. LCD displays this RMS Value of vibration amplitude. Please note the amplitude cannot over the maximum rated output amplitude; when finished, please set the amplitude to a minimum level.

15. Output: the output of adjusted sensors, the value is RMS;

16. Sens.: The sensitivity of calibrated sensor.
