AS Level Physics Circuits Question

I have a circuits problem which I think i may be able to solve on my own, except that the voltmeter in question is described as an 'accurately calibrated voltmeter'. Can anyone explain to me what this means, and if it will affect my calculations?
Help greatly appreciated!!
:cool:

All it means is that the voltmeter is set to zero when there is no potenital difference across the terminals. So voltmeters that are not properly calibrated, may have a systematic error associated with them. ie. all the readings they provide are wrong by so many volts. eg. a systematic error of +0.5 volts would mean that a reading of 2 volts would actually be a reading of 1.5 volts.
