Are you sure it is the tuning fork and not the reference for your counter? - 73 - Mike

I have stable (e-07) tuning forks which happen to jump too, and I don't understand why, even having under control temperature and air pressure. Sometimes they return to their prior frequency with another jump, and this could happen even days later, sometimes they jump and then recover smoothly the prior frequency in a short time (such as one hour). I have no idea whether any correlations would exist between crystals and tuning forks jumps, regarding the causes that could trigger metastability, and hence I would have a look at crystal data in order to improve the base for future speculation. Thanks in advance.
