10. Remove the orifice tube and clean it thoroughly (refer to
page 8-9
11. After cleaning the tube, check the orifice to see if it is unblocked; a good procedure
for doing this is:
a. Rinse the tube with cold tap water.
b. Holding the tube underneath the faucet, fill completely until it is in a meniscus
state.
c. Place your index finger over the top of the tube and press downward; this will
spew water out of the orifice if the tube is unblocked. You may have to hold the
tube against a darker background to obtain a clear view of the stream of water.
If the orifice is still blocked, call your Micromeritics Service representative.
12. Reinstall the orifice tube.
13. Prepare a new beaker of electrolyte and place it on the sample stand.
14. Raise the sample stand, submerging the orifice tube in the beaker.
15. Select Unit > Fill to fill the system with electrolyte.
16. Prepare a fresh sample mixture and restart the analysis.
