What is an Ambient Fail on an Intoxilyzer 8000C?

What does "ambient fail" or "ambient failed" mean on an Intoxilyzer 8000C?

Watch the following video and ask yourself why the ambient fail condition happens WHEN THE ADVERSE AMBIENT CONDITIONS ARE REMOVED. In the video, the AMBIENT FAIL does not happen when the experimenter holds an open container of Vodka close to the breath tube entrance during the initial air blank. How can this be?

Hint: Notice that the 45 mg/100mL dry gas alcohol standard indicates 000 on the cal. check.

Read the explanation for "ambient fail" in the CFS Intoxilyzer 8000C Training Aid. Does their explanation fit this empirical test?
