Agilent Technologies Helium Leak Detector
Indicates that the calibration routine was executed successfully.
Indicates that the leak detector is preparing for a calibration routine.
Indicates that filament 1 of the ion source has burnt out. Filament 2
automatically lights if it is still good, and a flashing C appears in the leak
rate exponent, indicating that a calibration routine is required.
Indicates that filament 2 of the ion source has burnt out. Filament 1
automatically lights if it is still good, and a flashing C appears in the leak
rate exponent, indicating that a calibration routine is required.
Indicates that the system is lighting the filament.
Indicates that the leak detector requires calibration.
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" on page 84.
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.
