100g, i.e., 200g, 500g, 1000g, etc., as long as the weight does not exceed the
maximum capacity of the balance. Use a calibration weight of at least 20% of the
total capacity of the scale (eg. 6kg for a 30kg capacity counting scale.
NOTE: The counting scale is calibrated at the factory and can be used out of the
box. It should be calibrated one time per year.

least 10pcs). Press PCS/SET to confirm.
As more units are added, the counting window will show the amount of units.
The total weight window will display the total sample weight.
The unit weight window will display the weight of a single unit.
NOTE:Use larger initial samples for more accurate results:
Pcs. Weight <0.3g = Not Accurate.
Pcs. Weight 0.3g-0.5g = Use 50+ pcs sample for counting function.
Pcs. Weight: >0.5g = Use 10+ pcs sample for counting function.

Use M+ to find the cumulative weight and piece count of samples. For
example, place a sample of 100 pcs (2kg) on the scale. Press M+ and remove
the sample. Add 50 pcs (1kg), weigh, and remove. Press M+ and the total
count (150 pcs) and weight (3kg) will be displayed.
Place the first sample on the weighing pan.
Once the weight is shown, press M+.
Remove the first sample from the weighing pan. The display will return to “0.”
Place the second sample on the weighing pan.
Press M+ again.
Remove the second sample from the pan. The display will return to “0.”
