No easy way . . . apply the correct voltage (I think regulated 5V?) and hook it up to an oscilloscope to measure the frequency . . . But I think it requires caps as well and I wouldnt know what values to use . . .

The one time I broke my crystal was because my robot fell 6 feet (about 8 times) . . . the sharp jostling would do it.

this is a pretty easy solution, no oscilloscope involved.
