14. CHECKING PROCEDURE General information This procedure is intended to check the oscilloscope performance with a minimum of test steps and actions required It is assumed that the operator doing this test is familiar with oscilloscopes and their characteristics WARNING Before switching on ensure that the oscilloscope has been installed in accordance with the instructions mentioned in Chapter 2 NOTE The procedure does not check every facet of the instruments calibration rather it is concerned primarily with those parts of the instrument that are essential to measurement accuracy and correct operation It is not necessary to remove the instrument covers to perform this procedure All checks are made from the outside of the instrument If this test is started a few minutes after switching on bear in mind that test steps may be out of specification due to insufficient warm up time Therefore to ensure accuracy allow the full indicated warm up time The following abbreviations are used CW Clockwise CCW Counter clockwise The brief checking procedure is set up in such a way that in a fixed sequence of ten steps the most important functions including all front panel controls are shown and checked At the end of each step the continuously controls must be reset to the previous setting As stated the procedure can be performed without removing the instrument covers For a complete check of every facet of the instruments calibration
