Hi everyone,
I have been playing around with my FY3224S in the Manual Trigger mode. My model seems to have some bugs here. I have attached some pictures showing the trouble.
At first I selected a sine wave of 1kHz. Then I pressed the “count” button three times to enter the Manual Trigger mode. In line 1 of the display I selected a count of 8 waveforms and pressed the button. 8 waveforms come out well on CH1. With 9 or 10 waveforms, the 2 latest waves come out wrong. From 11 onwards the output is ok. See pics A - D.
If I selected a square wave of 1 kHz instead of the sine, the 9th pulse is distorted (note the glitch to GND and an apparent longer “ON” time from 8-9 ms). See pic E.
If you select a slightly lower frequency, for example 0.995 kHz, the output shows a similar behaviour as with 1kHz plus an additional signal jump at 10.8 ms. See pics F - G.
At one time, the display got confused, showing “Manual Tri SINE”, but I forgot the exact button sequence to get this display. See pic H.
Can someone check these findings with his FY3224S? Do you get similar results?
