4. Press the measurement pan lightly and ensure that the display changes.
5. Release and ensure that the read-out indicator resets to zero.
3.2 Tare
1. Place a container on the balance. The balance indicates theweight of the item.
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.
Determining the weight of an added sample:
4. Press toreset theindication tozero.Thetotalweightofthe sampleloadedonthe measurementpanistared.
5. Load the additional sample. The balance indicates the weight of only the added sample.
Note
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.

Operation
Key Points of the Procedure
The following applies to all measurement modes for weight measurement, 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.
Note
If the balance is running on batteries and the unit is switched off, does not display.
• The bar graph shows the current load status withrespect to the capacity of the balance.As the F annunciator draws
near, the smaller the measurable weightbecomes.
Note
A subtracted tare weight is indicated on the bar even when though the display may indicate 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.
• When the read-out indicatoris reset to zero or the tare is subtracted, the balance displays
0
.
If the tare is subtracted, the indicator displays T.
• When the tare is present, the measurable range is reduced. The measurable range is the capacity minus the tare weight.
•If0-Err 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 offwhile in counting mode, the balance starts in countingmode the next time it is
switched on.
3.3 Counting
To implement piece counting, the specified samplesare loaded on the balance and their average unit weight (hereafter,
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 thebalance. The number ofpieces is
then calculated by dividing the total weight of the loaded articles by the unit weight saved in memory. Piece counting cannotbe
implemented unless sampling has already taken place.
Note
If samples to be counted deviate widely in weight, or a higher measure of accuracy is desired, seeSection 3 on page
10. This procedure results in greater precision by increasing the number of samples used in the sampling operation.
3.3.1 Sampling
1. Press to display Pcs.
2. Place the tare (measurement pan) and press . The tare is subtractedand the balance now indicates zero.
3. Press . The display flashes a number signifying the number of samples to be loaded. The sampling number
that was used in the previous sampling is displayed.
4. Press . Eachpressof thekey changesthevalue ontherightend.Select thedesiredvalue. Continue tostep
5 if the sampling number need not to be changed.
Note
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.

5. Count the samples carefully and load them inthe center of the measurement pan.
6. Press . The balance saves the unit weight and reverts to measurement mode.
Key Points of the Procedure
• The value indication turns off and M flashes to indicate that memory saving is underwaywhen samples are being saved.
If the balance is affected by wind or other vibrations during this process, the saving time may be prolonged.
•If  displays, 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.
• In the sampling of Operation Step 3, press with the samples loaded on the balance.
Note
 displays if the sampling is interrupted and the data in progress is not saved.
3.3.2 Increasing the Counting Accuracy (Memory Update Method)
The operation for increasing counting accuracy is referred to as the MemoryUpdate Method. This procedure updates the
memorywithaunitweightthatrepresentsa morepreciseaveragebygraduallyincreasingthe samplingnumber.Thisoperation
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.
• When greater accuracy is desired.
Note
If  displays in Memory Update Method, it indicates that a counting error is likely due to the small number of the
samples loaded on the balance. illuminates at LO. As the memory update continues, counting accuracy improves
and the above indication is no longer illuminated.
If the sampling number is changed, subsequent sampling starts from the new sampling number.
Note
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 centerof the measurement pan.
2. Press .The unit weight of the sample is saved, and a flashing value displays. Thisflashing value denotes
that the Memory Update method is currently active.
3. Add an approximately equal number of samples as the amount displayed. Add them in groups of about the same
number, until the number of samples is approximately double. The additional samples need not be counted.
4. Press . After the unit weight of the samples has been saved, the display begins to flash, indicating that the
Memory Update Method is still running.
5. Repeat steps 3 and 4. The total number of samples to be saved should be approximately 1/5 to 1/2 of the number of
samples to be measured.
6. Press . The balance saves the unit weight and returns to measurement mode.

Operation
3.4 Measuring
The percentage measurement function operates by weighing a reference sample and saving its weight as a reference value
and indexing it as 100% . When a measurement sample loaded on the balance is lighter or heavier than the reference, its
weight is indicated as a percentage (%) value relative to the reference weight.
1. Press to display % .
2. Press . flashes on the display. The balance is now ready for reference value setup.
3. Load the reference sample.
4. Press . The balance indexes the weight value of the reference sample as 100% and returns to
measurement mode.
5. The balance now indicates the weight of the loaded sample as a percentage (%) value relative to thereference value.
Key points of the procedure
• Whilesamplesarebeingsaved,thevalueindicationturnsofftemporarilyandonly Mflashes.Ifthebalanceis affectedby
wind or other vibrations during this process, the saving time may be prolonged.
• The minimum intervals between percentages in the unit switch from 1% to 0.1% to 0.01% depending on the reference
weight from the sampling.
•If displays briefly, it indicates one of the following states:
• The weight of the reference sample is insufficient. For the limit weight that can be saved (% limit weight).
• While setting up the reference value in Step 2, was pressed when the samples were loaded on the
balance.
Note
If  displays, sampling has been interrupted and the sample value being processed is not saved.
3.5 Battery Operation
Information in this section applies only when the balance is battery operated.
3.5.1 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
3.5.2 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.
Note
Charging the battery longer than 12 hours decreases battery life.

3.5.3 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 maybe shorter than when using a fully
chargedbattery.Thisis duetonaturaldischargeofthebattery.Althoughthebalancecan beused while isflashing,
it should be recharged as soon aspossible.
• When the battery displays no indication, oran 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.
CAUTION
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.

•If is set, no unit of measurement is displayed, even when units of measurement are set in subsequent parameters.
• cannot be set in .
• If the same unit of measurement is set multiple times, the second time (and all subsequent times) the unit(s) occurs, it is
ignored when the display switches.
4.3 Limit Function
Thelimitfunction judgesmeasurementsaccordingtoa limitvaluesavedin thebalance.Thefunctionshows thejudgmentresult
by displaying the annunciator as either HI (excessive), OK (appropriate), or LO (insufficient). This function is useful when
discriminating between conforming and nonconforming articles. It is also useful when measuring agiven constant quantity
consecutively, in conjunction with a range ofreference weights defined by upper- and lower-limit values.
This function can be used in weight mode, counting mode, or percentage mode.
4.3.1 Limit Value Input Methods
Either of the following two methods can be used in the different modes:
• Actual Quantity Setup Method - An actual sample is loaded on the balance; its weight is saved as the limit value.
• Numeric Value Setup Method - The limit value is entered with any key stroke.
Note
The limit values entered are held in memory, even when the balance is powered down. The respective limit values for
weight mode, counting mode and percentage mode are set up independently.
4.3.2 Indication of Judgment Result
The annunciator lights up as either HI, OK or LO on the left side of thedisplay, indicating the result of judgment.
Judgment Results Upper/Lower Limit Setting One-Point Setting
HI (excessive) Upper-limit value < measurement value No indication
