Paul, Graham, Tim, ... I've been on contact with Volker (universal-solder.ca) and Oren (ES100 designer). Here's what he says: > > The accuracy of the ES100 is limited to 50ms, since the sampling rate > is decimated to 20Hz in our final digital-processing stage there (this > was intended for human-read clocks and not for anything more demanding > than that), but better precision may be derived from it based on > averaging of consecutive readings.
