i.e.,
it can give you precisely the same wrong answer each time.

What are precision problems (as opposed to accuracy problems)?
Accuracy is conformity to a
"true" value. That is, a measuring instrument is accurate if it gives
you the same measurement as other calibrated instruments give -- a measurement
that has been independently confirmed to be real.
Precision is an
indication of the uncertainty in the measurement -- e.g., the number of
significant figures the measuring instrument reliably gives.
