16. Make desired adjustments to your oscilloscope settings and obtain a stable display.
17. Adjust the tips so both touch or are almost touching.
18. Connect both tips to the calibrator output signal.
19. Verify a straight line is shown centered on the screen. There should be no vertical deflection,
to indicate good CMRR.
20. One of the channels may be at fault if a square wave or part of a square wave is shown.
This concludes the functional tests of the WaveLink High Bandwidth Differential Probe.
