Refilling the dewar can be accomplished without disturbing the analysis data by first suspending the analysis using the ESCAPE key (WHITE + CLEAR) when you are ready to refill. The best time is during the saturation phase of the adsorption/desorption isotherm data-gathering.

After refilling, wait about 30 minutes to assure thermal equilibration, then again press the ESCAPE key (WHITE + CLEAR) and the analysis will resume.
