The majority of ammeters are connected in series and have a shunt 
resistor connected in series too. 
Since the ammeter shunt has a very low resistance, wiring the ammeter in 
parallel with a voltage source will cause a short circuit, at best 
blowing a fuse, possibly damaging the instrument and wiring.
In short an external or internal shunt is required when fitting an 
Ammeter. Is this what Frans refers too?
