Successfully passing Hardware Self Test does not guarantee 100% of the
oscilloscope's functionality. Hardware Self Test is designed to provide an 80%
confidence level that the oscilloscope is operating properly.
To perform front panel self test
Pressing [Utility] > Service > Front Panel Self Test lets you test the front panel keys
and knobs as well as the oscilloscope display.
Follow the on-screen instructions.
Failures in the front panel self test indicate problems with the keyboard, keypad, or
display.
To verify default setup
The oscilloscope is designed to turn on with the setup from the last turn on or
previous setup.
To recall the default setup:
1 Press the [Default Setup] key.
This returns the oscilloscope to its default settings and places the oscilloscope
in a known operating condition. The major default settings are:
• Horizontal:
• main mode.
• 100 us/div scale.
• 0s delay.
• center time reference.
• Vertical:
• Channel 1 on.
• 5V/div scale.
• dc coupling.
• 0V position.
• probe factor to 1.0 if an AutoProbe probe is not connected to the channel.
• Trigger:
• Edge trigger.
• Auto sweep mode.
