Gross leak
g
Check the torque of the
screws
of the analyzer cell, sealing surface
(spray helium to check it) and
elastomer
seal
status.Change
it
if
necessary.
g
Electrical short

Check electrical
connections
on the

located on the top of the analyzer cell.
Dismantle
and relocate
correctly the internal wires and/or connections.
g
Check the
status
of the filament by
measuring
the
resistance
of the
filament
(connect

Let
the leak
detector
run until you have a stable signal for the
degassing
and starting another auto-calibration.
Note: A low background gives a more accuracy measurement.
