Its always kind of thrown me off, so just to be sure I'm measuring correctly...

Using a multimeter to measure current, with the dial set to 200mA, the digital readout says 06.7
Does that mean 67mA?

 

If you have a battery and a resistor, and you know Ohm's law, check it yourself.

 

I assume you're talking about using a current clamp with your multimeter? If so, that would depend on the output specs of your current probe. Most of the probes I've dealt with put out 1 mA for every 1A measured (1mA/A). I've also seen 100 millivolts/A, 10 mV/A, and others.

Assuming a 1000:1 ratio (1mA/A) current probe, if your meter is on any mA range, you simply read the number as amps. In your case, it would read as 6.7mA

 

On 3-1/2 digit meters, the 200mA range setting will measure from 0.0 to 199.9mA.

The display is in mA.

When possible, you're better off measuring voltage across a known resistance than to measure current directly. When measuring current, if you accidentally touch the probes across a low impedance source of current, you will instantly blow the meter's fuse.

I have a precision 1 Ohm 50 Watt resistor that I use for such measurements. Since I = E/R, reading voltage across the resistor translates directly to current in Amperes.

 

On the other hand, if you're measuring current inline, then what you see is what you get. 6.7 on a 200mA range is 6.7mA. On a 20mA range, you get more accuracy (you might instead read 6.73mA). On a 2A range, you can measure higher currents, but with less accuracy - it would probably show as 1A.
