8. BALANCE CALIBRATION 
 
To ensure very high accuracy of weighing, periodical entering to memory 
correction factor of balance indication referring to standard mass is required; it 
is so called balance calibration. In WLT balances it is inaccessible for user. The 
procedure of calibration can be performed only by authorized services of the 
manufacturer.
