Overview of the Adjustment Process
Before performing adjustment procedures, you must warm up the oscilloscope
for at least 30 minutes in an ambient temperature between 20
°
C and 30
°
C.
Adjustments performed before warm-up or outside this temperature range may
result in poor performance or calibration failure.
The factory adjustment procedure consists of a series of steps; as you move
through these steps, the oscilloscope display provides instructions that describe
the specific 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 difficulty completing the steps, refer to the
Completing the
Procedure
section for specific instructions and troubleshooting information.
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
