How did you test the caps - with a capacitance meter or ESR meter?

I there i used a capacitance meter to test them but i removed every cap out of the board to test them?

Really need an ESR meter to check them. The capacitance can be ok but the cap still be bad. What are the voltages coming out of the power supply?
