3.1 Weighing Mode

Repeatedly press Unit until the desired unit icon is displayed.
Press 0/T to zero the balance and then place objects to be weighed on the pan.
3.2 Count Mode
- Use the Count mode to count parts of uniform weight.
To access Count Mode, press Unit until the display shows [Count].
Establish an Average Piece Weight (APW) - Each time a new type of part is to be counted, the nominal weight of
one piece (APW) must be established using a small quantity of pieces.
With [CLr.APwW] displayed, press No to use the previously saved APW, or press Yes to establish a new APW. The
display indicates the number of pieces to be used to establish the new APW. If a different sample size is preferred,
press No until the desired sample size is displayed (5, 10, 20, 50 or 100). Put the specified number of pieces on
the pan. Press Yes to accept new APW or No to abort.
Count - Place the quantity to be counted on the pan.
APW Optimization - Since the weight of each piece varies slightly, APW Optimization may be used to increase the
accuracy of the count. The balance automatically recalculates the Average Piece Weight when the number of parts
on the pan is less than three times the original sample size. The display shows [APwW.OPT] each time the APW is
