Problems
Problem/Meaning Remedy
Selected temperature is too high and the 
sample is oxidized;  
sample is boiling or burning and the 
splashes are continuously changing the 
weight.
– Reduce drying temperature
– Lay glass-fiber filter onto the sample
– Reduce the sample quantity or apply 
the sample more evenly
– Select a semi-automatic switch-off 
criterion or select timer mode
Measurement time too long – Increase temperature
– Reduce sample quantity
– Preheat the analyzer by running a 
drying process for 2 or 3 minutes 
with an empty sample pan, for 
example
Sample loses weight before it is analyzed – Remove the sample pan and apply 
the sample outside the analyzer
Sample is liquid or pasty – Use glass fiber filter
Sample has only a low moisture content – Increase sample quantity
Insufficient heating output – Clean temperature sensor
Place of installation unstable  
(vibrations, etc.)
– Set up the scale in another area
