Repair Procedures
This section gives detailed descriptions of procedures to repair the
instrument. Always disconnect the instrument from line power before repair.
WARNING To disconnect the instrument from line, pull out the power cord. The
power supply still uses some power, even if the power switch on the
front panel is turned off.
For exchange of electronic assemblies we recommend to use an antistatic
grounding kit (part number 9300-0933) to prevent the electronics from
damage by electrostatic discharge.
• Before you unpack any electronic replacement parts, connect yourself
electrically to the instrument with the help of a wrist strap.
• Connect the packing material with the electronic replacement part to the
instrument.
• Touch electronic boards only on the corners and avoid touching the metal
traces and electronic items on the board.
• When you remove electronic assemblies from the instrument, always put
them back into the antistatic bags or place them on a material that has an
electrical connection to the instrument.
