Ion Source Header Pin Schematic - Agilent Technologies VS Series Operation Manual

VS Series Component Leak Detector
17. On the PCB, use the resistance meter to verify an open circuit between any two of the
six ion source header pins (except FIL-1 to FIL-1 and FIL-2 to FIL-2 which should be 0.3
Ohms or less). Also verify an open circuit between the body of the spectrometer and any
of the ion source header pins (Figure B-56). If there is continuity (short circuit) at any of
the points, remove the header and inspect for shorting.

18. Re-Install the cover with the four screws.
19. Re-plug in both cables and ground strap.
20. Verify that turbo vent valve is closed.
21. Leak check the spectrometer to ensure a leak free joint.
22. Close the cover and secure using existing hardware.
23. Power up the leak detector.
24. Let the unit run for 20 minutes, then perform a calibration (via the I/O, front panel
display or RS232), per the user manual, to validate a successful installation.
