Remedy
● Ensure that the pressure is below the maximum
operating pressure: < 5 × 10
● Check the ion source elements and analyzer ele-
ments for short-circuit and insulation.
● Ensure that the wiring screws are securely fas-
tened.
● Replace the filament unit, the ion source or the
analyzer.
● Make sure that the electronic unit (QME) has
been completely pushed onto the analyzer .
● Ensure that the contacts are straight and are not
bent or damaged.
● Check that all settings are correct.
● Use the settings from the test report for orienta-
tion.
