How to test capacitors of non working circuit board using capacitor meter?
It is not possible to test the capacitors while they are still soldered onto the board. Because the capacitors are connected to other things, the measurement will not be accurate. This is especially true of power decoupling capacitors, where the measured capacitance will actually be the sum of all the decoupling capacitors.

As an alternative I would suggest using a continuity device to check for shorts. Since your meter does not have that feature, you can use the ohm-meter to check that out. An excessively low number will indicate a capacitor short.
