ANLSERR: Eq failure

ANLSERR: Fill failure
NN/ZZ cycles completed
ANLSERR: Overrange
NN/ZZ cycles completed
Cause A: The sample being analyzed failed to equilibrate in 1000 seconds.
Action A: Check the system carefully for leaks as described in Checking the Cell
and Expansion Chambers for Leaks later in this chapter. Make sure the
sample is properly prepared before performing an analysis.
Cause B: Sample (foams, organics, etc.) absorbs helium slowly.
Action B: Set the equilibration rate to progressively higher values until
reasonable equilibration times (15 sec to 120 sec) are achieved.
Cause: There was insufficient pressure to allow filling within five minutes
during an analysis.
Action: Increase the regulator pressure or, if there is insufficient helium in the
tank, obtain a new tank of helium.
Cause A: A pressure overrange occurred during an analysis because the regulator
pressure is set too high.
Action A: Adjust the pressure so that it is equal to the higher of the two fill
pressures specified in the analysis parameters plus 2.0 psig.
Cause B: A pressure overrange occurred during an analysis because an error
occurred in the pressure measurement electronics.
Action B: Call a Micromeritics Service Representative.
