Frequently Asked Questions - VA 20 PCE Instruments
What is the PCE VA 20 used for?
The PCE VA 20 is a vibration meter designed to measure acceleration, velocity, and displacement of rotating machinery and equipment to assess condition and predict failures.
How do I change the battery in the VA 20?
Turn off the device, slide the battery cover at the back, remove the old 9V battery, and insert a new alkaline 6F22 battery. Ensure correct polarity and close the cover securely.
What does the auto power off feature do?
The VA 20 automatically turns off after 5 minutes of inactivity to conserve battery. Press any button to wake it up.
How accurate is the VA 20?
The accuracy is typically ±5% of reading within the specified frequency and measurement ranges. For best results, calibrate annually.
Can I measure vibration on all surfaces?
Yes, but use the included probe for consistent contact. For rough or curved surfaces, use a magnetic or adhesive mount (optional accessories).
What do the measurement units mean?
Acceleration in m/s² indicates vibration intensity; Velocity in mm/s relates to vibration energy; Displacement in µm shows physical movement.
How do I switch between measurement parameters?
Press the UNIT button repeatedly to cycle through acceleration, velocity, and displacement. The corresponding symbol appears on the display.
Is the VA 20 suitable for industrial environments?
Yes, it's designed for field use. However, avoid extreme temperatures, humidity, and magnetic fields. Use the carrying case for protection.
Does the VA 20 store measurements?
The device has data hold and min/max recording but does not have internal memory for storing multiple readings. You must record values manually.
How do I clean the device?
Use a soft, dry cloth to wipe the exterior. Do not use solvents or water. Clean the sensor tip gently with a lint-free cloth if dirty.
