Depends whether the meter is digital or analoge, where the other clip is and
what you are trying to measure. If you were measuring the voltage wrt
ground at any point then the +ve of the meter would normally be connected to
ground and the negative to whatever you are measuring. Getting the clips
the 'wrong' way round on a digital meter would do no more than show the
voltage as negative. On an analogue meter the needle would try to go the
wrong way, but some meters have a 'reversal' button so you would just push
that. In any case, reversing the polarity is not as damaging as overdriving
the movement.
