What to do if Micromeritics AccuPyc II 1340 don't turn on?
- A
  Angela RobertsonAug 5, 2025
  If nothing happens when you turn on your Micromeritics Measuring Instruments, start by ensuring the power cord is fully inserted into both the outlet and the unit. Check if the outlet has power by plugging in another device. Wiggle the power plug to see if the display comes on, which may indicate bent prongs. A damaged power cord could also be the cause, so have an electrician inspect it. If none of these steps work, there may be a loose internal connection or a failure of the external power supply, and it is recommended to contact a Micromeritics Service Representative.

What to do if Helium drained from tank of Micromeritics AccuPyc II 1340?
- R
  Regina MooreAug 20, 2025
  If helium is draining from the tank in your Micromeritics Measuring Instruments, it could be due to leaks in the gas line connection. Pressurize the system, then close and open the Cylinder Shut-Off Valve; if the pressure gauge needle jumps abruptly, check the gas line connections. Another cause could be leaving the pycnometer in manual mode with all valves open, or having the fill valve open with the chamber cap off. To resolve this, close all valves and attach a new tank of helium.

How to fix Micromeritics AccuPyc II 1340 Measuring Instruments that will not equilibrate?
- S
  Stephen NguyenAug 28, 2025
  If your Micromeritics Measuring Instruments won't equilibrate or the results aren't reproducible, it could be due to sample outgassing, so remove moisture and contaminants from the sample prior to analysis. Pycnometer leaks can also cause this issue, so check the cap O-ring for defects and regrease or replace it if necessary. Additionally, if you're using a 2000 cm3 unit, the dust filter might be clogged or leaking, so clean the dust filter.
