Error/Display
Drying operation is not aborted until after
3'10", 3'30" or 5' although the sample no
longer loses weight
The message ERROR appears in the display
The reproducibility of the results is unsatis-
factory
Possible cause
•Minimum drying time 3'10"/3'30"/5', de-
pending on the setting of the abort criterion
• Admissible temperature range exceeded
• The sample material is inhomogeneous in
regard to moisture
• The sample material is hygroscopic or
contains highly volatile substances that
evaporate even before the start of the
infrared drying
• Film formation at sample surface
• Drying is incomplete since it has been
prematurely terminated
• Small amount of sample
• Low moisture content
Rectification
• Perform new setting or use time-controlled
switching off
• Disconnect power connector and plug in
again
• If error message remains, inform
METTLER TOLEDO service
• Increase amount of sample
• Calculate mean values
• Change sample preparation
• Use blotting paper to increase surface area
• Increase amount
• Prolong time
