Walfront AS63D Digital Vibration Meter

1. Introduction

The Walfront AS63D Digital Vibration Meter is a high-sensitivity accelerometer vibrometer pen designed for accurate measurement of vibration. This device utilizes a piezoelectric acceleration transducer to convert vibration signals into electrical signals, which are then analyzed to display acceleration, velocity, and displacement values. Its portable design and clear LCD backlight make it suitable for various applications in power, petrochemical, machinery manufacturing, metallurgy, and vehicle industries.

2. Safety Information

• Read all instructions carefully before operating the device.
• Do not attempt to disassemble or modify the device. Unauthorized modifications can lead to malfunction or injury.
• Keep the device away from water, high temperatures, and corrosive environments.
• Ensure proper battery installation and replacement. Use only recommended battery types.
• Avoid dropping the device or subjecting it to strong impacts.
• When measuring, ensure the probe is securely attached and the measurement point is stable to prevent injury or damage to the device.

3. Product Overview

The Walfront AS63D features a user-friendly design with an LCD display and intuitive controls. Key components include:

• Measuring Probe: Used to contact the object for vibration measurement.
• A/V/D Button: Selects between Acceleration, Velocity, and Displacement measurement modes.
• LO/HI Button: Selects the frequency characteristic (low or high frequency range) for acceleration measurements.
• MEAS/ON Button: Short press to turn on the device, long press to initiate measurement.
• LCD Display: Shows measurement values, battery status, and selected modes with backlight for clear reading.

4. Setup

4.1 Battery Installation

1. Locate the battery compartment cover on the back of the device (refer to Figure 3).
2. Slide or unclip the cover to open the compartment.
3. Insert the required batteries (typically AAA, check device markings) ensuring correct polarity (+/-).
4. Close the battery compartment cover securely.

4.2 Probe Selection

The AS63D comes with different probe options to suit various measurement conditions:

• Short Probe Tip: This is the factory default. It is suitable for wide-scope vibration measurements and provides good response values.
• Long Probe Tip: Included in the carry box, this tip is designed for measurements in narrow spaces or on special objects, allowing for quick response.
• No Probe Tip: For measurements on smooth object surfaces, the device can be used without a probe tip to obtain stable values.

Select the appropriate probe tip based on your measurement needs and screw it firmly onto the measuring probe connection point.

5. Operation

5.1 Power On/Off

• To turn on the device, short press the MEAS/ON button. The LCD display will illuminate.
• To turn off the device, long press the MEAS/ON button until the display turns off. The device may also have an auto-off feature after a period of inactivity.

5.2 Measurement Mode Selection

Press the A/V/D button to cycle through the measurement modes:

• Acceleration (A): Measures the rate of change of velocity.
• Velocity (V): Measures the speed of vibration.
• Displacement (D): Measures the distance an object moves from its equilibrium position.

The selected mode will be indicated on the LCD display.

5.3 Frequency Characteristic Selection (Acceleration Mode Only)

When in Acceleration mode, press the LO/HI button to select the desired frequency range:

• LO (Low Frequency): For measuring vibrations in lower frequency ranges.
• HI (High Frequency): For measuring vibrations in higher frequency ranges.

5.4 Taking a Measurement

1. Ensure the correct probe tip is attached for your application.
2. Turn on the device by short pressing MEAS/ON.
3. Select the desired measurement mode (Acceleration, Velocity, or Displacement) using the A/V/D button.
4. If in Acceleration mode, select the appropriate frequency range (LO/HI) using the LO/HI button.
5. Firmly press the measuring probe against the surface of the object whose vibration you wish to measure.
6. Long press the MEAS/ON button to initiate the measurement. The device will analyze the vibration and display the results on the LCD.
7. Read the displayed value. The LCD backlight ensures clear visibility.

7. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: When not in use for extended periods, remove the batteries to prevent leakage. Store the device in its protective case (Figure 6) in a cool, dry place, away from direct sunlight and extreme temperatures.
• Probe Care: Keep the probe tips clean and free from debris. Ensure they are not bent or damaged.
• Battery Replacement: Replace batteries when the low battery indicator appears on the LCD.
