Hi Everybody!
I just got Pico standard kit + WPS500+ Firstlook sensor + new 2000 Amp clamp.
Made test with friend Volvo CR diesel engine ( just test, car is 2 years old and no problems )
Couple questions came out:
1. With Pico diagnostics battery test I connected voltage probe with crocodile straight to alternator and message, that no voltage signal. Measured with scope B channel and there definitely was voltage. Put croc to battery directly and we at least got some measurements.
We run test and I also added new 2000A clamp on channel B.
It showed that about 150 A during crank ? I expect at least 250 A during crank on engine. I did not saw any place for amp clamp selection ( 600 vs 2000 A )

I have my own Opel Zafira A with mechanical diesel pump. Any clue, how to determine 1. cylinder on it ?, because there is no electrical injector on it. Also, I need to deal with other old mechanical diesel engines .
I have used a diesel piezoelectric sensor on the number 1 cylinder fuel line. They come with different sizes, so be aware of this - if you choose to buy one. The piezoelectric sensor produces a small voltage.
