Someone needs to measure the voltage at the transformer (voltage
in and voltage out). Remember that using a digital meter can
result in measuring AC voltages that are really not there.
A high impedance source. The voltage is really there, but the source
has a VERY low load capacity.
True. Voltage but almost zero current potential.
Possibly leading to inconsistent readings on different ranges of an
analog meter (meter causes a different load on each range).
You are too use to professional level meters. :-) Most digital meters
OP's will have low enough resistance they would be lucky to get any readings
of voltage no matter what range they used. :-)
Of course you are right.
