Hello everyone, I recently bought this colorimeter but I'm having troubles getting it to work on my mac. Going through the mailing list archive I found something similar to what's happening to me (see attached log).
Hi, looking at the log, it seems that your instrument is faulty. It returns the error 1B "NEEDS_OFFSET_DRIFT_CAL" which is described as "A valid offset drift calibration does not exist". I would say it needs to go back to the factory for a re-calibration, since important calibration information seems to be missing. Graeme Gill.
