Operation of Level Monitor
Once the cover with the monitor has been placed on the
vessel and plugged in, it will take the system about 15 min-
utes to equilibrate before an accurate measurement of the
liquid nitrogen will be indicated. This equilibration process
will occur each time the vessel is used. Each time a vessel
is opened, the stabilized chamber temperature is disrupted.
The system requires a stable temperature to determine an
accurate liquid nitrogen level.
If you have just purchased a new LOCATOR or LOCATOR
Plus along with your monitor, allow at least 1 day for the liq-
uid nitrogen to equilibrate the vessel before plugging in the
unit. This will avoid false alarms.
