[Therion] Detecting errors

[Ben Cooper]

An error of 3 degrees in clino does indicate a device out of calibration.  I would expect it to be within 0.5 degrees for a well calibrated device, and would not tolerate more than 1 degree.  In my experience poor calibration is usually down to either just inaccurate calibration shots, or local magnetic anomalies: take off watch, step counter, metal belt buckle, jewellery, glasses, helmet, lights, steel toe caps, etc!!
