C-1 Spectrometer (Ion Source Assembly) - Agilent Technologies VS Series Operation Manual

PD03 - Verify that the diaphragm pump is functional, electrically (running) and
creating a vacuum.
Spec Tube message error appears on the front panel display
This error can also occur during normal operation.
Causes/Resolutions
1. Spectrometer pressure is > 7E-3 due to a gross leak:
a. Select Setup menu > Gauge Calibration menu and ensure that the Spectrometer
Pressure reading is < 1E-4 Torr.
b. Check for a gross leak at the turbo inlet, spectrometer centering ring or at the
spectrometer header (O-ring misaligned) or entire spectrometer.
2. Spectrometer pressure is >1E-4 due to a misaligned, incorrectly assembled or
contaminated total pressure plate:
a. Disassemble the spectrometer header from the spectrometer body and inspect the
total pressure plate (Figure C-1 and Figure C-2).
