How sensitive is the NCV feature?

I called it a name and it still works. It detects LED voltage on Christmas tree lights from about 5 inches away... you may find your meter has feelings, but mine seems to not care about sensitivity.. it just indicates voltage is present.

Do the Battery Test selections test under load?

The M4KOR model does the 1.5v - 9v - 12v battery tests each is under a small load, and does test the battery voltage as part of the DC volts ranges. The M6KOR model does NOT perform battery tests under load, but does test the battery voltage as part of the DC volts ranges.

Would you choose this model or another for automotive diagnosing?

To answer your question I'm a master Automotive technician most of the people in the business use flukes but our use these ones because they are accurate and work just as good as the fluke when it comes to Automotive Diagnostics. There is nothing you can't do with this digital multimeter that you can do with a fluke

I have been trying to measure the ac/dc amps with this but doesn't work. i wanted to know if i am missing something or its actually faulty?

Make sure you have the leads in the proper slots or ports for the amperage reading.
