The rear of the vibration meter displays the battery compartment cover and a label indicating the functions of the buttons and display elements, including 'MEAS/ON' button, 'LO/HI' frequency selection, 'A/V/D' mode selection, and AC output.

2.3 Probe Attachment

The meter comes with both long and short probe heads. Select the appropriate probe head for your measurement application and securely screw it onto the sensor at the top of the device.

3. Operating Instructions

3.1 Powering On/Off

  • To power on the device, press the "MEAS/ON" button.
  • The meter features an automatic power-off function, turning off after approximately 60 seconds of inactivity to conserve battery.

3.2 Selecting Measurement Mode

Press the "A/V/D" button to cycle through the measurement modes: Acceleration (m/s²), Velocity (mm/s), and Displacement (mm). The selected mode will be indicated on the LCD display.

3.3 Frequency Selection

Use the "LO/HI" button to switch between low and high frequency measurement ranges. Refer to the specifications for detailed frequency ranges for each mode.

3.4 Taking Measurements

  1. Ensure the correct probe is attached and the desired measurement mode (A/V/D) and frequency range (LO/HI) are selected.
  2. Firmly press the probe tip against the surface of the object to be measured.
  3. The measurement value will be displayed on the LCD.
  4. For stable and precise readings, ensure consistent contact pressure and placement.

3.5 AC Signal Output

The device includes an AC signal output interface (2V peak, display full scale). This allows connection to external devices such as oscilloscopes or data recorders for further analysis. The load impedance should be 10KΩ or more, or earphones can be connected.

4. Maintenance

4.1 Battery Replacement

When the low battery indicator appears on the LCD, replace the 9V Alkaline battery as described in the "Battery Installation" section (2.2). Prompt replacement ensures accurate readings and continuous operation.

4.2 Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or display. Keep the probe tip clean for optimal performance.

4.3 Storage

When not in use for extended periods, remove the battery to prevent leakage. Store the meter in its protective carrying case in a cool, dry environment, away from direct sunlight and extreme temperatures.

5. Troubleshooting

ProblemPossible CauseSolution
Device does not power on.Battery is dead or incorrectly installed.Check battery polarity or replace with a new 9V Alkaline battery.
Inaccurate or unstable readings.Loose probe connection, incorrect frequency/mode selection, or improper contact with object.Ensure probe is securely attached. Verify correct mode and frequency. Apply firm, consistent pressure to the object.
Low battery indicator displayed.Battery power is low.Replace the 9V Alkaline battery immediately.
No AC signal output.Cable issue or external device problem.Check the connection cable. Ensure the external device is functioning correctly and has appropriate input impedance.
