Zero Check Weighing
Zero check weighing is used when comparing subsequent samples to an initial reference sample. In
this case, the UNDER limit must be a negative value and the OVER limit must be a positive value.
Place the reference item on the scale and press TARE. Remove the reference sample and place the
item to be compared on the scale to determine if it is within the ACCEPT range.
If the item is lighter than the UNDER limit, the yellow UNDER LED will light. If the item is within the
target weight range, the green ACCEPT LED will light. If the item is heavier than the OVER limit, the
red OVER LED will light.
