FILL AND INSTALL THE DEWAR
Dewar Precautions on page6 - 1
The equipment images in this topic may differ slightly from your equipment; however,
the instructions are the same unless otherwise noted.
1. Fill the Dewar with the analysis bath liquid (such as liquid nitrogen) to no higher than
21/4in. (5.7cm) from the top. Filling the Dewar higher than this will cause an error in the
free space measurement.
Incorrect fluid levels can lead to measurement errors. Check the level of the bath
liquid before each analysis.
2. Insert the dipstick and check the level of the analysis bath liquid. Condensation should not
exceed the level indicator mark.
