Error messages

Sometimes, a problem in your MSD will cause an error message to appear in the
MSD ChemStation software. Some error messages appear only during tuning.
Other messages will appear during tuning or data acquisition. Sometimes, instead
of a message, only a number will appear. This number will represent one or more
error messages. To translate a number into an error message:
1 Note the number.
2 Select
Diagnostics/Vacuum Control
3 Select
MS Error Codes
4 Type in the error number and press
The corresponding error message(s) will appear.
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.
