I have an old XT computer with a crystal oscillator that I would like to test.

My multimeter has a Mhz setting that as far as I know should allow me to test it. (Providing the crystal is powered)

The problem is that most of the time during the measurement the computer crashes. About 1 out of 10 times am I able to see a constant measurement (the actialactual frequency also displayed on the oscillator), but only for a couple of seconds. Most of the time the pc crashes as soon as I touch 1 of the 2 leads.

I would like to ensure that it is operating correctly. Is this normal and as such not the proper way to test ? Is there another way to determine the crystal is in good working order ?
