Note: *1) If using a sample of 10 pcs., press PIECES key without entering a number of
sample.
Note:*2) To have accurate unit weight calculation, the sample weight must be more
than the insufficient range of the scale. (Insufficient range = 0.0% ~ 0.7 % of
scale capacity) If sample weight is less than the range, the number of pieces
required for accurate sampling would be displayed in PROCEDURE 3.
NOTE: *3) When the unit weight is developed though sampling, the accuracy can be
improved by increasing the sample size using recomputing feature. This
function works only when the “RECOMP” sign lit.
