Warning
Troubleshooting and repair of this instrument without the cover exposes high
voltage points that may, if contacted, cause personal injury. Maintenance and
repair of this instrument should, therefore, be performed only by a skilled
person who knows the hazards involved. Where maintenance can be performed
without power applied, the power should be removed. When any repair is
completed, be sure that all safety features are intact and functioning and that all
necessary parts are connected to their grounds.
Assembly Level Text
To locate troubleshooting information for an individual assembly, refer to Table 6-1.
Block Diagrams
Instrument-level block diagrams are located at the end of this chapter. Power levels and
voltages shown on block diagrams are provided as a troubleshooting aid only. They should not
be used for making instrument adjustments.
