1 Disconnect any external cables from the front panel.
2 Disconnect the power cord, then remove the cabinet
following the instructions on
Series models or
USE AN EXTERNAL FAN TO AVOID OVERHEATING COMPONENTS !
When you remove the oscilloscope cover and main shield, use an external fan to
provide continuous air flow over the heat sinks. Air flow over the heat sinks is
reduced when the cover and main shield are removed, which leads to higher than
normal operating temperatures. Have the fan blow air across the system board
where the heat sinks are located. Otherwise, damage to the components can
occur.
If the cover of a 6000A Series oscilloscope is removed but the main shield remains
installed and the bottom holes are not blocked, the instrument will cool properly.
HAZARDOUS VOLTAGES EXIST — HIGH VOLTAGE IS PRESENT ON DSO6000L
SERIES POWER SUPPLY HEAT SINKS !
The power supply heat sinks of the 6000L Series oscilloscopes are at a high
potential. This presents an electric shock hazard. Protect yourself from electric
shock by keeping this area covered or by not coming in contact with the heat sinks
when the power cord is attached to the oscilloscope!
