Hi, the limit at the moment is set at a scan time of 15 seconds. This determines the buffer size used to store the raw readings. You'll have to tell me whether that is long enough for a high quality (ie. not scanning too fast) scan of your longer ruler. If not, it's easy enough to increase. Graeme Gill.
