Basic Operation
3.2 Operation Key Points
The following applies to all measurement modes for weight measurement, tare, counting and percentages.
• After the balance is switched off, there is still enough current to display . This indicates that the AC adapter is
connected to an electrical outlet, but the balance is turned off. When the balance is switched on again, turns off.
If the balance is running on batteries and the unit is switched off, does not display.
• The capacity bar graph shows the current load status with respect to the capacity of the balance. As the capacity
annunciators draw near to the F annunciator, the smaller the measurable weight becomes.
Figure 3-4. Capacity Bar Graph
A subtracted tare weight is included in the capacity bar graph, even when the display indicates zero.
• The stability indicator is on as long as the balance is stable. It does not display if the balance becomes unstable.
When a displayed value flickers or the stability annunciator flashes on and off, it is likely that the balance is being
affected by wind or other vibrations. Use the windshield or vibration dampers to protect against such adverse effects.
Figure 3-5. Stability Annunciator
• When the read-out indicator is reset to zero or the tare is subtracted, the balance displays .
If the tare is subtracted, the indicator displays .
• When the tare is present, the measurable range is reduced. The measurable range is the capacity minus the tare weight.
• If displays when a sample is loaded, the measurable range has been exceeded.
• In counting or percentage mode, the indicator does not change, even when the measurement pan is pressed, if no
sample is stored in the memory.
• The active measurement mode on startup is the mode that was active when the balance was last switched off. For
example, if the balance was switched off while in counting mode, the balance starts in counting mode the next time it is
switched on.

3.3 Tare Procedure
1. Place a container on the balance. The balance indicates the weight of the item.
Figure 3-6. Taring a Container
2. Press to tare the weight of the item. The weight (tare) is subtracted and the balance indicates zero.
3. Load the sample to be weighed. The balance indicates only the weight of the sample loaded in the container.
Figure 3-7. Weighing a Sample
Determining Additional Sample Weight
1. Pres s to reset the indication to zero. The total weight of the sample loaded on the measurement pan is tared.
Figure 3-8. Taring Initial Sample
2. Load the additional sample. The balance indicates the weight of only the added sample.
Figure 3-9. Weighing Additional Sample
When the weight of a sample currently loaded on the measurement pan is reset to zero with the Zero/Tare key, only
the weight of the newly added sample is measured.

Basic Operation
3.4 Battery Operation
Information in this section applies only when the balance is battery operated.
3.4.1 Specifications
Built-in nickel-cadmium battery
Charging time Approximately 12 hours
Drive time Approximately 24 continuous hours
Number of charge/discharge cycles 300 or more
3.4.2 Charging Method
While the balance is battery-operated, the full battery indicator stays on. The charging required indicator flashes
when the battery capacity decreases. If the balance flashes , charge the battery by following these steps:
1. Connect the dedicated AC adapter to the balance.
2. Turn off the balance.
3. Charge the battery for approximately 12 hours, with the power switched off.
Charging the battery longer than 12 hours decreases battery life.
3.4.3 User Precautions
• Once charging is complete, use the balance without the AC adapter to avoid over-charging. This can occur since the
balance continues to charge the battery with a weak current when the power is switched on. Overcharging also
decreases battery life.
• When the balance is used for the first time after purchase, the operating time may be shorter than when using a fully
charged battery. This is due to natural discharge of the battery. Although the balance can be used while is flashing,
it should be recharged as soon as possible.
• When the battery displays no indication, or an indication turns off quickly after the balance is switched on, battery
capacity is low. In these cases, either charge the battery immediately, or plug in the AC adapter.
• Charging the battery while is displayed reduces battery life.
Observe the following to operate the balance safely; failure to do so could result in malfunctions, breakage,
burst batteries, or fire:
Do not disassemble or modify the battery.
Do not reverse the balance connection or short-circuit the positive and negative polarities of the balance.
Use only the supplied AC adapter.
Do not incinerate used batteries. Dispose as hazardous material only.

5.0 Counting Pieces
To implement piece counting, the specified samples are loaded on the balance and their average unit weight (here after,
referred as unit weight) is entered and saved. The procedure for saving unit weights is called sampling.
The counting procedure consists of loading articles that have already been sampled onto the balance. The number of pieces is
then calculated by dividing the total weight of the loaded articles by the unit weight saved in memory. Piece counting cannot be
implemented unless sampling has already taken place.
Figure 5-1. Sampling and Counting Pieces
If samples deviate in weight, or a higher measure of accuracy is desired, see Section 5.3 on page 17. This procedure
results in greater precision by increasing the number of samples used in the sampling operation.
5.1 Sampling
1. Press to scroll through unit of measurement options until Pcs displays.
2. Place container on the measurement pan and press . Container is subtracted and balance indicates zero.
3. Press . The display flashes a number signifying the number of samples to be loaded. The displayed
sampling number was the number used in the previous sampling.
Figure 5-2. Sample Number Entry
4. Continue to step 5 if the sampling number does not need to be changed or press to change the number.
Press key until desired number displays.
If samples deviate in weight, or a higher measure of accuracy is desired, it is recommended that users change the
sampling number to a larger value.
5. Count the samples carefully and load them in the center of the container.
6. Press . The balance saves the unit weight and returns to measurement mode.
