Maintaining The Electronics - HP 5973 Hardware Manual

Maintaining the electronics

The MSD electronics do not require any scheduled maintenance
None of the electronic components of the MSD need to be replaced on a
regular schedule. None of the electronic components in the MSD need to be
adjusted or calibrated on a regular schedule. Avoid unnecessary handling of
the MSD electronics.
Very few of the electronic components are operator serviceable
The primary fuses can be replaced by the operator. The RF coils can be
adjusted by the operator. All other maintenance of the electronics should be
performed by your Hewlett-Packard service representative.

Electrostatic discharge is a threat to the MSD electronics during
maintenance
All of the printed circuit boards in the MSD contain components that can be
damaged by electrostatic discharge (ESD). Do not handle or touch these
boards unless absolutely necessary. In addition, wires, contacts, and cables
can conduct ESD to the printed circuit boards to which they are connected.
This is especially true of the mass filter (quadrupole) contact wires which
can carry ESD to sensitive components on the side board. ESD damage may
not cause immediate failure but it will gradually degrade the performance
and stability of your MSD.
