But to repeat it again:
There's no way to make the unit cycle 250 times per second if the pulse frequency is 250 and have it reflect in the display. What you see is perfectly normal. The display "samples" the output of the pulse at a different frequency of the pulse, so it may sample the pulse while its rising, falling or even at the bottom of the top. It's not random, but to your mind it may appear that way. There's no way to make those sync up. If the display cycled 250 times per second, you wouldn't see anything but 888 likely. When setting the pulse after it is first turned on, you have several seconds in which to set the pulse before the display starts cycling. If you go beyond that default time, you have two choices. 1) Turn it off and then back on to finish setting, 2) Turn pulse frequency to a minimum and the display will cycle slowly enough to register. For me, I just set pulse to a minimum to start with and adjust pulse frequency last.
