nance intervals.

First read through the sections completely

Read the section with the work instructions through completely first before you commence
with work.

9.1 Execution of maintenance work

Maintaining the analyzer QMA 250

The analyzer ages in normal use and does not require preventive or regular maintenance work.

► Carry out a visual inspection of the analyzer.
► Eliminate malfunctions and faults resulting from a contaminated ion source or from a contaminat-

ed analyzer using the degas function of the ion source or by baking out the analyzer.

► Check whether you can achieve better results with the settings from the test report before you

perform wide-ranging maintenance work.

– Inadequate sensitivity, malfunctions, and faults may also be due to incorrectly set ion source

parameters.

Maintaining the electronic unit QME 250

The QME 250 electronic unit does not normally require any repairs or maintenance.

► Contact

Pfeiffer Vacuum Service

9.2 Test report

The test report lists the ion source parameters which have achieved good results during the final in-
spection at the factory.
