Level Offset
Since the annular line that carries the pressure level signal to
the Controller is not located at the very bottom of the LN
column, a Level Offset is needed. This value is determined
and set at the factory and should not be adjusted to fix an
inaccurate level reading unless setting up a freezer (see the
"First Fill Startup procedure") or if instructed to do so by
an authorized CryoExtra Distributor or Technical Service. For
liquid level calibration see section "Liquid Nitrogen Level
Calibration".
Note: Security Level 3 or higher is required to adjust the Level
Offset.
