Description
Indicates that the gain value required to calibrate the leak detector during the calibration
routine is greater than the maximum allowable value. This is generally the result of system
sensitivity being too low, due to normal system aging.
Indicates that the gain value required to calibrate the leak detector during the calibration
routine is less than the minimum allowable value. This is generally the result of a system leak.
Indicates a high Helium background detected during calibration self-test. This typically,
indicates a vacuum system leak.
Indicates a tuning/calibration failure due to the system not detecting an ion peak during the
auto-tuning routine.
Indicates an electronics failure identified during calibration self-test.
Indicates that the system is setting the Offset value.
Indicates a test object failure during an Auto Sequencer Test cycle. See "Auto Sequencer".
Flashes red when the spectrometer pressure > 1.0E-4 Torr.
Indicates that the system is waiting for the electronics to stabilize before completing the
startup routine; up to two and a half minutes.
Indicates that the optional internal calibrated leak is being roughed before it is introduced
directly to the system for calibration verification.
Indicates that the system is momentarily in the process of switching from a burnt out filament
to the next available filament.
Indicates that the system (spectrometer) pressure is too high to light the ion source filament.
Indicates that the system is ready for testing. This message appears only during the initial
startup and is cleared after the first test cycle.
Indicates that the leak detector is in the process of Zeroing out a background signal. The Zero
routine is initiated automatically during the startup and calibration routines, or manually when
the operator presses the Zero button on the Home screen.
Indicates that the system is setting the initial zero values during the startup routine.
