28. 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 (Error! Reference source not found.
circuit) at any of the points, remove the header and inspect for shorting.
29. If successful, leak check the spectrometer to ensure a leak free seal.
30. Place the spectrometer cover over the header and align the holes (Figure 2-13Error!

32. Re-plug in both the pre-amp and ion source cable.
33. Reinstall the leak detector covers and fasten hardware.
34. Power up the leak detector.
35. Let the unit run for 20-30 minutes, then perform a calibration (via the I/O, front panel
display, or RS232), per the user manual, to validate a successful installation.
