Aren't you supposed to calibrate any measurement equipment across its full measurement range? That could take some time! :lol:

Well.. true. All of our timers/stopwatches are in perpetual calibration. The users get mad because the equipment is not available for use; but not my problem!! I let them know that the 5 year time verification is just about done!:tg::lmao:

Just a thought, but one could just open the stop watch, and make a measurement of the actual crystal timebase. 32,768 Hz if I remeber correctly in most cases. This method eliminates the repeatabilty of the Techs reaction time, and ups the actual measuremt resolution provided you have a decent counter, or sig gen and oscope. This shudl get you the MUC needed for just about any MFR spec. Now the UC of the stop watch in use is still goign to have issues, but the cal is solid.
