Operation 9
If samples to be counted deviate widely in weight, or a higher measure of accuracy is desired, it is
recommended that users use the “Raising the Counting Accuracy” method. This procedure results in greater
precision by increasing the number of samples used in the sampling operation.
2.3.1 Sampling
9. Press key to display [Pcs].
10. Place the tare and press . The tare is subtracted and the balance now indicates zero.
11. Press . The display flashes a number, such as [  ]. This means that ten samples are to be loaded. The
sampling number that was used in the previous sampling will be displayed here.
12. Press . Each press of the key changes the value on the right end. Select the desired value. Continue to step
5 if the sampling number need not to be changed.
If samples to be counted widely deviate in weight, or a higher measure of accuracy is desired, it is
recommended that users change the sampling number to a larger value.
13. Count the samples carefully and load them in the center of the measurement pan.
14. Press . The balance saves the unit weight and reverts to measurement mode.
Key Points of the Procedure
1. While the samples are being saved, the value indication disappears and only [M] flashes to indicate that memory
saving is underway. If the balance is affected by wind or other vibrations during this process, the saving time may be
prolonged.
2. If [  ] appears, it indicates one of the following states:
• The weight of one sample (measurable unit weight) is insufficient. For the range of unit weights that can be measured
and saved, please refer to “Specifications” on page 26.
• In the sampling of Operation Step 3, press with the samples loaded on the balance.
If [

] appears, the sampling is interrupted and the data in progress is not saved.
3. The operation for increasing counting accuracy is referred to as the Memory Update Method. This procedure updates
the memory with a unit weight that represents a more precise average by gradually increasing the sampling number.
This operation improves counting accuracy and is recommended for the following cases:
• When the samples to be counted deviate widely in weight or the number of samples displayed deviates.
• When greater accuracy is desired.
4. If [  ] appears in Memory Update Method, it indicates that a counting error is likely due to the small number of the
samples loaded on the balance. [ ] will light up at the judgment indication
LO
. As the memory update continues,
counting accuracy improves and the above indication disappears.
5. If the sampling number is changed, subsequent sampling will start from the new sampling number.
2.3.2 Increasing the Counting Accuracy (Memory Update Method)
This procedure is the same as the sampling procedure described on the previous page, to the point at which
the sampling number is changed.
1. Count the samples carefully and load them on to the center of the measurement pan.
2. Press . The unit weight of the sample is saved, and the display changes to a flashing value. This flashing
value denotes that the Memory Update method is currently active.
3. Add approximately an equal number of samples as the number currently displayed. Add them generally, in groups of
