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.
WARNING

Maintenance is performed with power supplied to the oscilloscope and with the
protective covers removed. Only trained service personnel who are aware of the
hazards involved should perform the maintenance. Whenever possible, perform the
procedures with the power cord removed from the oscilloscope.
