RE: My meter is scaled to 200 ma.

When you measured it, did the needle deflect? A volt meter will put 0.1 to 0.2 volts or so out when measuring resistance. Be careful with a meter as you can easily fry it by putting too much voltage or current on it if there is no internal or external shunt or voltage divider.

If your meter is set up as an ammeter, it will have a shunt resistor that the volt meter measures across. So, if the scale is 0.2A or 200mA, a 1 ohm shunt (internal or external) will make the meter see 0.2v at full scale. Good ol' Ohms Law.
