Replacement Parts
This chapter contains instructions for removing and ordering
replaceable assemblies. Also included is a parts list for the assemblies
and hardware of the oscilloscope that you can order from
Hewlett-Packard.
Before working on the oscilloscope, read the safety summary at the
back of this book.
WARNING
Hazardous voltages are on the CRT, power supply, and display sweep board.
To avoid electrical shock, disconnect the power cord from the oscilloscope.
Wait at least three minutes for the capacitors in the oscilloscope to
discharge before you begin disassembling the oscilloscope. Read the Safety
Summary at the back of this manual before beginning disassembly.
CAUTION
Do not replace assemblies with the oscilloscope turned on, or damage to the
components can occur.
CAUTION
ELECTROSTATIC DISCHARGE (ESD) can damage electronic components.
When using any of the procedures in this chapter, you should use proper
ESD precautions. As a minimum, you should place the instrument on a
properly grounded ESD mat and wear a properly grounded ESD strap.
