Error Messages
Sometimes a problem in your MS will cause an error message to appear in the
MassHunter Workstation software. Some error messages appear only during
tuning. Other messages may appear during tuning or data acquisition.
Some error messages are "latched." These messages remain active in your data
system even if the condition that caused the message has corrected itself. If the
cause is removed, these messages can be removed by checking instrument
status through the data system.
Difficulty in mass filter electronics

Difficulty with the photo multiplier or
microchannel device

Difficulty with the fan
If a cooling fan fault occurs, the vacuum control electronics automatically shut
off the high-vacuum pump, the ion source, and mass filter heaters. Therefore, the
message: "The system is in vent state" may also appear. It is important to note
that even though the high-vacuum pump is off, the analyzer chamber may not
actually be vented. See
for precautions to take.
