Re: motor rpm photo tach sensor

Hi NathanUnger, Instead of advice about probe, here is how I would approach this: Basically, I need to get accurate RPM from device that rotates in direct ratio to engine RPM. Then it is so easy to get the accurate RPM waveform for anything directly geared to engine, belt or gear, as long as there i...

Re: Need to know how much capture time will be saved

Hi, this is solved by using function named "action", I am using it extensively for exactly the reason you have named here. This "action" function will keep your scope recording until the buffer is full, then automatically save the file to your hdd and start capturing new data, then after buffer full...

Just small update, I have added the CAN ID in decimal numbers and sorted from small to high.

Re: Interesting CAN BUS fault on 2018 Landrover discovery

Hi RYM6746, Just by looking on your waveforms, the good one has high load compared the problematic one. I mean there is so many more frames sent on the good one, it is probably due to engine not running when you have captured the waveform of faulty vehicle. Also by looking at the affected frames, it...

Re: Setra 517 HD Clutch position sensor

I would try all what Ben advised and also unplug the sensor as you suggest, to see if the signals will both go high. If the bearing is not an active actuator itself but a sensor only, and as you said there are two potentiometers, it sounds like a double signal sensor, as back up like design where th...

Re: Setra 517 HD Clutch position sensor

Hi flaurits, Here is my explanation: First how such sensor/device works. (I may be wrong as I have never seen such machine) If it is what I think, many such applications are in passenger cars. There is a PWM signal from the ECU which is desired position of the device, then the device carry out the t...

Re: Kia Ceed 3 1.6 diesel alternator ripple test

Hi, The best practice to find out where the spikes come from is to use other channel and read other signals. For example if the injectors would be the spike sources, the signal (falling or rising edge) would always match the spike on the original signal (here it would be your alternator ripple wavef...

Re: Connecting scope stalls engine

Thank you for the update.
If you would have time, please try to upload the waveform here.
It will help many other Picoscope users as we all need to learn.
And this forum here is the best place to share our stories from real diagnostic situations.
Best Regards,
Roman

Re: Giving Up on the Source

Hi Josh, I have personal experience from Bentley dealerships where noise is extremely important to customers as the expectation is far higher than at premium brands as Mercedes or Audi. The NVH plays major role in decision and demonstration to customer (printed report) where customer feels the "nois...
