My multitester doesn't react - Skil 2100DAF Digital Angle Finder

There are several reasons why the tester doesn't react..try to check these:
1. Check the safety fuse inside it.
2..The test lead set (the red & black wire w/ pin )
might have cut inside it,particularly in the part of
ends,near the pins/plugs.
3. The bateries might be o voltage and need to be
replaced.,or if the batery is good,just clean the
contact or teminal of the bateries.( a common
multi tester have 3 bateries, composed of 2 size
"AA" & 1- 9volts size.) these bateries are all
assigned to the "continuity"section of the tester.
(these are: X1;X10;X100 ; X 1K & X10K. )
so,if the tester is not functioning only in that
section,the first thing you have to check are the
bateries.Now.if you replaced the bateries with
new one but it is atill not working,then we go
back to my tip number 1 above.,that is to check
the test lead.
3. if you already finish checking the above method
and it still not working,then there is a problem in
the resistors of the system.

But, is your tester is digital? if it has no power: just simply check the fuse & batery..But if it has a power but not working when you use to test,you jst check the test lead or the selector switch becos the contact inside might be loosen.
