Here is the version details of my DSO -
Hardware Ver V2.70
DS203 Mini DSO SYS Ver 1.52
DS203 Mini DSO APP (PLUS A1) Ver 1.00

@shoeb

1. Is it the latest one?

HW: Yes

@shoeb

2. I can set 10v maximum in ChA and ChB. So, is it the maximum voltage that can be seen using 1X probe?
   10V/scale …

@shoeb

If yes, using 10x probe I can view only 100v. Right?

100V/scale (respect max. of the probe)

@shoeb

3. How I can enable auto measurement?

There is no “fool proof” button; you need some knowledge how to use an oscilloscope.
