PicoScope 2204A vs Hantek HT-25. Here we show how to set the custom oscilloscope probe in PicoScope 7 for the Hantek HT-25 secondary ignition clamp. We are using the PicoScope 2204a, however the probe settings should apply to any oscilloscope or secondary ignition probe. The waveform file can be found in the Mechanic Mindset Waveform Library at mechanicmindset.com

Using the non-automotive Pico 7 software and the 2205a, when adding new probe is selected the equation pops up and you simply input 10000 volts and choose volts and not KV, all reading will be correct. There appears to be no need to copy from Pico automotive.
This was an excellent info video as per usual. The Pico scope 7 software is very easy to use even for this old guy. Some computer experts and programmers complain on some forums, perhaps they have limited knowledge of automotive requirements and suggest that they view your videos.
That’s right, it’s very easy! I think people who have used Pico 6 for a long time are still in the change curve. Maybe there are deeper reasons they don’t like it. We only scratch the surface of the PicoScope software capabilities 👍
Thanks Darren,, Pico must send you all there latest machine's no charge 👌,, All your good pico ,, report and hard work
We do some work with Pico Automotive already 😁. But not for these types of oscilloscope as the are not optimised for automotive 👍
@MechanicMindset If I’m using a Hantek HT25COP ignition probe wand. Do I need to use an attenuator on my pico scope 2204a?
Thanks Darren
Like you said the pattern looks very grainy even after slight clean up. I find it useless if cannot see the spark-line/burn time.
Thanka mate , i buy pucoscope 2204A and practising that , thanks much !
Great! Enjoy
again nice info. darren thanks for sharing your knowledge as always.
Thanks for the video. I have a little hard time to hear what you say at about 2:50. But i think that you tell us that the probe did not have attenuator(think it show 12v when you touching the battery), so you must connect an external attenuator? But isnt the voltage at the secondary ignition 40000-50000v? Is there so powerfull attenuators to buy?
Yes, no attenuator (possibly some components to clean the signal). The attenuator isn’t needed because we aren’t physically measuring the kV, just the magnetic field around the wire. The custom probe gives us the approximate relative kV reading. Hope that helps
@@MechanicMindset Thank you. I watch the video one more time after your comment, and now i fully understand. Almost feel embarrassed😀
@@AN77 It’s important you ask! Many others are thinking the same but will never ask. Thanks!
When i close the time panel, invert turns off. If i open the zoom pop.up the invert turns off. If i do injector + secondary the signal invert turns off. Any idea of this strange behaviour of not keeping the invert on? Even though the invert button is pressed?
Hey I'm just starting to get into Scopes thank you for all your videos you didn't need to use an attenuator for this?
Not needed, the put out voltage is actually very low for this probe 👍
Hi Good video. Can I use pico scope 2000 with software picoscope 7?
Thank you..
Yeah for sure! That’s what I’m using here. Normal Pico 7 though 👍
I am thinking of renewing my 2204A for the 2406B with 4 channels, 50MHz bandwidth, sample rate: 1GS/S unlike the 2204a having 100MS/S, rise time 7ns unlike the 2204a which has 35ns . I think it would go well, what do you think???
It will be a bit better, good memory too but I really think it’s best to save a little more and go for the 4425A. The 2000 series is still an 8bit scope with common grounds. And no access to any of the Automotive goodies. I got the 2405A recently and it’s great step up from the 2405a, still shares limitations 👍
So the 2205A will work with the automotive version of the pico automotive software?
Great video Mate.
Thanks
Very clear video, thank you. I have one probably quite dumb question. That probe seems to have no protection at all (as you said, no attenuator.) If the HT lead is faulty (i.e. insulation breaking down), do I risk sending kilovolts through the Pico into my laptop? Or is it going to go to ground through the probe's ground?
Hmmm, maybe it will go to ground, I’m not sure what has less resistance. I will try to find out. It in my list of videos to make actually: see if it can take the spike 🤣
@@MechanicMindset I'll let you try that with your laptop :)
Is there no way to use the automotive pico scope software with the 2204a?
I just read in the Pico Forum that the 2000 series scopes are not made for use in the automotive industry. In other words, they are not made to be used on cars, more for lab work. Is this true?
What they generally mean by that is that the 2000 series is not suitable for high voltage testing since that would fry the 2000 series oscilloscopes. It can measure up to 20V but I believe it has protection up to 100V. It also has common ground instead of individual grounds per channel, which can cause some issues in very specific cases.
In general the 2000 series is great for Automotive just make sure you use an Attenuator when you're working on things with higher voltage. 👍
Also automotive version have presets for sensors,coils etc,. But using presets you will really never learn how to properly setup a scope
@@mandytuning what automotive scope do you recommend?
I signed up for free access and cannot find waveform library. Please let me know where it is. Great videos btw
Hi, it’s in courses called TH-cam Wavefoms. The downloads are under the videos. 👍
Hi Darren
Just buyed the Topdon Phoenix Max, which comes with a 4-channel Oscilloscope.
Is it possible to use the Hantek pins and attenuator?
For sure! It all works as long as it’s BNC.
I have the same scope to do a video on soon, but with the ThinkTool Max/S20. Hope to get it up in the next couple weeks; just working it out 😁
@@MechanicMindset looking forward to see
good info! i think i used 1000x10 on my mp408 and have setup 1kv-100kv will have to test it out next time i get pug wires! thanks bob
Ah ok cool! Let us know how it goes 👍
@@MechanicMindset can I email you ?
@@MrMexanik066 Sure!
@@MrMexanik066 info@mechanicmimdset.com
Is it possible to use the pico Software with a Hantek scope ?
No
Should you use the attenuator with it if that isn’t one on the cable
No, it’s not needed. This only picked up around 1V actual voltage reading
@@MechanicMindset oh cool got all the stuff now going to try it and a ripple test on alternator too 👊🏻
I’m Assuming if you’re using DSP and you’re comparing multiple channels while you lose the amplitude you should still be able to make a comparison between the different channels if there’s something wrong. I hope that makes sense.
For sure, if they all have the same DSP applied, you’re still just looking to compare the waveforms
Same like one video for cc650 amp how to create pico 7
2204Apico
Any kind of car can be compression tested by picoscope
Yeah, pretty much
I don't see the ignition probe option on the PicoScope7 T&M
No it’s not there, Automotive only. This video shows you how to set it up in T&M
podrias ayudarme con el hack para usar picoscope 7 automotive, please, I can use the same hack, which I use for picoscope automotive 6?
Not possible th-cam.com/video/QfWS05bJMWU/w-d-xo.html
great video
Thanks Alexy! Have you got an ignition clamp?
@@MechanicMindset yup i have just the same setup as yours with the same oscilloscope as yours and in few weeks im going to test the ignition on my old BMW motorcycle.
P.S. where i can get the extension between the COP and the spark plug?
@@alexybodom You can find the Hantek HT308, although I have PicoScope version
@@MechanicMindset okay thanks a lot 😊
Hi great videos .Just invested in a pico scope 2040A but for use on JCB Agg and construction machines .After 30 years the technology used in these machine has gone through the roof so it’s time to start learning again . Just looking at your on line learning to see if it would be useful for me in my job and would be interested in your thoughts . Cheers allastaire
Awesome. Yes we have many Agricultural, commercial and heavy diesel students. Make sure you get some attenuators; assuming you’re 24V?
Hi mixture of both 12 and 24 volt even as low as 8,5 volts
