PIECE COUNT: SAMPLING
If an unknown piece weight is to be determined you may do this by sampling a
certain number of pieces. The number of pieces taken from or placed on the
weighing system determines the accuracy of the sampling. The total weight of the
pieces taken from or placed on the weighing system for the sampling should be no
less than 4-5 kg. The greater the weight difference, the greater accuracy. The
standard sampling amount is 10 pieces, but this number can be increased up to 95
pieces.
NOTE: If the accuracy is too low when sampling, the indicator will show "ERR05".
