Hmm, Very dodgy website with not a great deal of information. Doesn't seem to read many code groups - about half a dozen for the 4200 and about a dozen for the QP's but less if you disregard the MY variant's..
This seems to be the pertinent bit of information...
You need to know one think! this is a Tester not a Engineer!
You need to buy it from a Company that can help
if you needed...
This seems to imply that you can read, but you can't adjust...
Best avoided?
