3 Calibrating and Adjusting
This chapter explains how to adjust the oscilloscope for optimum operating
performance. You should perform self-calibration according to the following
recommendations:
• Every two years or after 4000 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.

maintenance. Whenever possible, perform the procedures with the power cord removed from the
oscilloscope.
