Reply to "True RMS"

bmoran4OGR Forum Member

A true RMS meter is needed only when accurate measurement of non-pure sine wave AC Voltage is what is sought. All of Lionel's classic transformers from the pre and postwar era are pure sine wave. For amp readings, true RMS is not a significant factor. I use an inline series meter as the doughnut clamp style ones require an external power supply of sorts.
