This is a list of the most common faults/actions. For other warning/messages/issues 
and for more advanced troubleshooting you must contact a FOSS representative. 
You will then be instructed on how to proceed and if a service visit is required. 

 

Global H (GH) and Neighbourhood H (NH) are two statistical warnings indicating 
that the sample and the calibration do not work together. Either the wrong 
calibration is selected or the sample is not properly represented in the calibration 
set. 

A typical way to reduce the number of warnings and errors based on GH and NH is 
to add those samples to the calibration set. Take the samples, scan them, make a 
reference (chemical) analysis and add them to the calibration. 

This is typically done together with an application specialist from FOSS or from 
your own organisation.
