does this work "close enough" to get idea if power supply is good (low ripple) ?
"
A ripple voltage is a small AC voltage, which is placed on top of a DC offset. It can be measured using a digital multimeter.
Plug the probes into the digital multimeter. Two probes are normally supplied. Plug the red probe into the positive terminal and the black probe into the negative terminal. Switch on the digital multimeter by turning the dial on the front panel clockwise.
Select the "AC Voltage" by turning the dial on the front to the picture of an oscillatory wave. Bring the probes into contact with the circuit that has the ripple voltage. The multimeter will only measure the AC component of the signal -- i.e., the ripple voltage.
