Adjustment Procedures
The factory adjustment procedure consists of a series of steps; as you move
through these steps, the oscilloscope display provides instructions that describe
the speci
fi
c input signal requirements for each step. If the oscilloscope passes the
step, it moves on to the next step. If the oscilloscope fails, you can repeat the
step or choose to abort the procedure.
If you have dif
fi
culty completing the steps, refer to the
Completing the Procedure
section for speci
fi
c instructions and troubleshooting information. (See page 3-6.)
To complete the calibration procedure, you must know how to operate the
oscilloscope calibrator. Please refer to the user manual, which can be found at

NOTE.
Do not turn any knobs or push any front-panel buttons other than the Next
Step or Previous Step buttons during the adjustment procedure. Doing so will
cause the oscilloscope to abort the adjustment procedure. The oscilloscope uses
the previous calibration constants if the adjustment procedure is aborted or fails.
The screen does not display the actual oscilloscope settings (such as channel input
impedance, or vertical and horizontal settings) during the adjustment procedure.
The oscilloscope automatically sets the instrument settings, but these settings may
not read out correctly on the display.
During some steps, the instrument may appear to be idle for several minutes while
it is processing information internally.
If the oscilloscope completes all steps in the procedure successfully, a "Pass"
message is displayed and the new calibration constants take effect. If the
oscilloscope does not pass a step, you can repeat the step. To cancel the calibration
procedure, press the
Menu Off
front panel button on the oscilloscope. This
reverts the oscilloscope to the old calibration constants.
Factory Adjustment Procedure
To perform the factory adjustment procedure, complete these steps:
1.
Connect the oscilloscope to an AC power source.
NOTE.
You must connect the oscilloscope and the test equipment to the same
AC power circuit. Connect the oscilloscope and test instruments to a common
power strip if you are unsure of the AC power circuit distribution. Connecting the
oscilloscope and test instruments to separate AC power circuits can result in offset
voltages between the equipment, which can invalidate the adjustment procedure.
2.
Power on the oscilloscope and warm it up for 30 minutes.
