A pressure underrange occurred during the first pass of calibration
because an error occurred in the pressure measurement electronics.
Call a Micromeritics Service Representative.
The calibration standard failed to equilibrate in 1000 seconds during
the second pass of calibration.
Check the system for leaks (refer to Checking the Cell and
Expansion Chambers for Leaks in Chapter 5).
There was insufficient pressure to allow filling within five minutes
during the second pass of calibration.
Open the tank valves if shut, increase the regulator pressure or, if there
is insufficient helium in the tank, obtain a new tank of helium.
(Minimum recommended tank pressure is 200 psig.)
A pressure overrange occurred during the second pass of calibration
because the regulator pressure is set too high.
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.
A pressure overrange occurred during the second pass of calibration
because an error occurred in the pressure measurement electronics.
Call a Micromeritics Service Representative.
