UNI-T UT81B Automotive Use

hi I have used this graphing meter for a few years now and it has been in a few of my videos, occasionally I get asked about it's ability for automotive use. I decided to put a short video together to demonstrate it at work. it's a single channel graphing meter, and still has some use to the technician in the automotive industry. there are times that you need two or more channels, I hope this helps thanks for watching.
