Hi Martin, just a follow up i could not reproduce duty cycle wave form using manual settings, i only showed you that setting to explain what i was seeing, i am investigating this further as i am suspecting that this fan might not be controlled by PCM i will update when i get more accurate info. Chee...

Martin thanks for the heads up i will definitley give it a try and report back. the reason i went to the guided test is that the first time i dreamed duty cycle on the Chrysler the scope setup the parameters automatically for me this is where i got confused and went to the guided test, which i norma...

Hi martin, I've sent you the waveform as per instructions, As for the test i have simulated with the probe when the scope was connected to quickly touch the ground wire on & off to simulate the test you has suggested, yes i see a square wave. which is confusing/frustrating me as im thinking what am ...

Hi Martin, thank you for your reply, I am not seeing a square wave pattern. the first time i measured duty cycle i was measuring instrument cluster light dimming, I connected the scope and the software automatically set parameters. and the square wave was displayed. The engine fan i used the paramet...

Hi to all, i have a issue in that i not getting the duty cycle to show on the screen. the test i was carrying out was engine fan duty cycle. i had connections correct as i could measure with a DMM. i have measured duty cycle before successfully, but with the latest software i have not. Also i tried ...

Hi I'm David from Melbourne Australia, I teach automotive to apprentices and I'm looking forward to using the picoscope in the classroom, also i hope to share any knowledge that i have. I have used oscilloscopes before but the picoscope is a excellent tool, powerful and easy to setup which makes dia...
