The procedures that follow allow you to quickly compensate the calibration
of the oscilloscope for any external temperature variations. This ensures the
most accurate measurements. No test equipment is required to perform
these procedures.
Optimum instrument performance depends on the recommended
20 minute minimum warmĆup time prior to performing the following
calibration routines. All calibration routines require a successful
completion (no failed" message).
The Temperature Compensation Calibrations affect the accuracy of
the display system; therefore, they should only be performed by a
qualified technician.
