Why is the vacuum on my Micromeritics ASAP 2460 Measuring Instruments making a loud noise?
- L

  If the vacuum system of your Micromeritics Measuring Instruments is making a continuous loud noise, it could be due to several reasons. First, ensure that the sample tube fitting is securely tightened with a wrench. If the noise persists, inspect the sample tube O-ring for wear or cracks and replace it if necessary. Another potential cause is a cracked sample tube, which would require replacement. Lastly, check if a sample tube is loaded on the selected port and that the port valve is closed. If not, install a plug or empty sample tube on the port. If the valve is open, enable manual control and use the instrument schematic to close the gas inlet valve.

What to do if vacuum gauge shows high reading on Micromeritics ASAP 2460 Measuring Instruments?
- D
  David CunninghamAug 12, 2025
  If the vacuum gauge on your Micromeritics Measuring Instruments shows a reading above 20 µmHg, even after extended pumping, consider these potential causes. If you're using an oil-based pump, the vacuum pump oil level might be low, causing ineffective evacuation; in this case, add or change the vacuum pump oil, ensuring it reaches the proper level according to the indicator window on the pump. Check the pump's power plug, switch, and circuit breaker to ensure the pump is receiving power. A dirty filter in the port being used could also cause this issue; replace the port filter to resolve it.
