Title: relative compression test on 24 volt system.
Post by nero411 on Jun 12^th, 2017 at 5:13am

Greeting to you all.

this keep bothering me for quit a while but didn't find the time to send this post.

I work as field tech for caterpillar dealer so most of the machine are 24v, i found that i cant perform a relative compression test & pico keep send this massage (see attach file) the raw voltage is out of screen as well. i didn't find any way to do change configuration that will set for 24v.
I use the 4425 four channel diesel kit.

any suggestion? did i missed something?

The other thing i would like to know is about save my scope file in a well organize comfortable & ease way of using it, like the good old program from AES WAVE information management system (that unfortunately doesn't support win 7 & up).

Any ideas on this topic?

Thanks in advance.

Nir

Have you tried the battery test instead?

The battery test has a button for 24V and you can hook up High Amp clamp to channel B and attach it to the battery negative cable and crank it over.

Yes I'm quit aware of those tests. Basically this what i did for relative compression test i used the current clamp.
As for battery test there is no issue for me.

Thanks.

Hi Nero I'm a Diesel guy myself. I have never used Pico Diagnostics but I can try it out myself when I get back to work. Make sure you go to Cummins Bus, I have a lot of good stuff on there for us Diesel Techs. :) Any questions let me know. :) Nice to have another Diesel guy. We are starting to grow in numbers which is awesome! Hallelujah! For awhile I thought I was talking to myself when I first got on this forum,lol. ;D

Hi Nir,

There is a newer software version out for PicoDiagnostics. The current software version is 1.9.5.2724 so it may be worth updating then trying again. Let us know how you get on!
