outgas rate.
The gauge is updated when the Analysis Manifold Test is run. See
Start Diagnostic Test on page9 - 1.
n
Three green LEDs are lit if outgas rate is below 30% of outgas rate
limit.
n
At 30%, the left LED turns off.
n

n
At 90%, three green LED lights turn off and the center yellow
LEDturns on.

Displays statistics of the saturation pressures measured with nitrogen
gas at liquid nitrogen temperatures. The mean, two-sigma, minimum,
and maximum values display. The gauge is updated when a P
0
is
