Ripple voltage can be measured most accurately
with an oscilloscope. However, an alternate way to
get an indication of ripple voltage is with a CE
meter (PN 1749231).
a. Connect a capacitor (0.22 uF or larger, 50 Vdc
or higher) in series with one of the meter leads.
b. Set the meter to a range that will read 2.5 Vac.
c. Connect one meter lead to the dc voltage in
question, the other lead to frame ground.
(Remember, a capacitor is in series with one
of the leads.)
d. If the meter pointer leaves zero on the meter
scale, excess ripple voltage may be present.
