2.10.5 Pulse Interval Accuracy Test
Wire the units as in the figure below, enter all settings (PWM output settings), then
confirm that the criteria are met.
The figure below shows an example of wiring CH5. Actual measurment should be
performed on all channels.
Use an external power supply of 5 V, load resistance of 100 Ω, and a counter trigger level
of 2.5 V.
