It couldn't be "out of calibration" to the extent that it couldn't measure
voltages to within 5% or better unless it was failing completely.  I calibrated
stuff for a living at one point in my life, and nothing really drifts even 1%
since we got rid of tubes/valves and electrolytic capacitors.  Modern DVMs are
quite good.
