Question: 

Can you zero the test leads on the ohm setting?

Answer: 

        This is what we call  “zero-ing” the leads or zero offset. Normally it works for those meters which have “REL” button displayed have zero-ing setting (see pic 1).

        It will also be mentioned in the user manual (specification section) if the meter can compensate for offsets (see pic 2) or it will be stated in measuring resistance section (pic 3).

        Simply press the “REL” button, it will zero-ing test leads.
