screw driver to remove the four screws securing it. The screw shown in the top right of Figure 3-4
will be securing a grounding strap. Leave the ground strap hanging from the leak detector frame.
Disconnect the two electrical cables plugged into the spectrometer board, the pre-amp RJ45 style
connector on the turbo side of the spectrometer, and the ion source multi-pin connector (Cables
not shown for clarity: refer to Figure 3-5). Remove the top cover, set aside with the screws.
