Calibrating and Adjusting
User Calibration 53
This chapter explains how to adjust the oscilloscope for 
optimum operating performance. You should perform 
self-calibration according to the following recommendations:
• Every 12 months or after 2000 hours of operation
• If the ambient temperature is >10 °C from the calibration 
temperature
• If you want to maximize the measurement accuracy
The amount of use, environmental conditions, and experience 
with other instruments help determine if you need shorter 
adjustment intervals.
Let the Equipment Warm Up Before Adjusting
Before you start the adjustments, let the oscilloscope and test 
equipment warm up for at least 30 minutes.
Read All Cautions and Warnings
Read the following cautions and warning before making 
adjustments or performing self-calibration.

hazards involved should perform the maintenance. Whenever possible, perform the
