DMM current measurement

I'm confused (so what's new?)

In the handbook (not to hand, so this is from memory) for my cheapo handheld dmm it states that for current measurement the voltage dropped by the meter is 200mV.

As far as I know, you use a shunt resistance to pass the current and measure the voltage drop across it - obviously not a fixed voltage drop. I've been looking and looking and looking on the internet to try to find out how this fixed voltage drop works - so far nothing doing. Anyone know what's going on here? Or could it be a mfr (Mastech) typo?

TIA
 
Oh, never mind, I found out. It means the voltage drop at full scale. Duh!
