6.1 ERRORS
The main screen will list any errors currently occurring on the instrument in the lower right corner. Operation error messages
will remain until the error condition is remedied. Operation errors relate to temperature and gas flow accuracy during
operation. Initialization errors will appear on bootup for 15 seconds and then disappear. Initialization errors relate to
calibration issues (i.e. if the unit is uncalibrated or if the yearly calibration is out of date).
