10.3 

Amount of substance and duration of the drying cycle. 

The composition of the substance affects significantly the duration and the accuracy of the 
humidity measurement results. 
A small amount of the substance will result in a faster drying cycle, but with less precise 
results. 
While a greater amount of the substance will need higher drying times but with more reliable 
and repeatable results. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Therefore, based on the substance, it’s necessary to determine the right compromise 
between the drying time and the accuracy of the results you want to obtain. 
 
 

11 Care and Maintenance 

Periodic maintenance of your balance guarantees the safety of your measuring tool. 

▪

 

Cleaning 

Before cleaning the balance, unplug the power supply unit from the wall socket. 
Do not use harsh products (solvents or similar agents), but a damp cloth with a mild 
detergent. Prevent the penetration of liquids into the device during cleaning; after cleaning, 
dry with soft cloth. Remains of sample and dust can be removed with the use of a brush or 
vacuum cleaner. 

▪

 

Safety checks

 

The safety of the device is no longer ensured when: 
-The power supply unit is visibly damaged  
-The power supply unit no longer works 
-The power supply unit has been stored for a long time in unfavorable conditions. 
In these cases, please contact the service center where technicians will perform any 

repairs to restore the device in a safe condition.
