    9. CHECKWEIGHING Checkweighing is a working mode using two thresholds (Min and Max) to control sample weight (LO - sample mass too small, HI - sample mass to large, OK - sample mass correct). Such solution enables fast evaluation of sample mass There is no need for constant control of the weighing result.
