PREFACE
Thank you for purchasing an SJ Series electronic balance. This is a precision instrument equipped with
exacting mechanisms in a compact body. The SJ series provides enhanced functions, including a
counting mode for stock control of parts, a percentage mode for comparative measurements given in
percentages, and a limit function for measuring constant quantities by consecutive weighings. Despite
its many functions, the balance is easy to operate and features user-friendly keys. Furthermore, the
large liquid-crystal display provides excellent visibility, and the instrument’s high speed and
stability−intrinsic to a tuning fork design−help boost operational efficiency.
Before using the balance, please check that the following items have been included in the
package.
Should you find any missing parts, please contact your local dealer or our marketing division at once.

3.
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 that the balance is turned off.
When the balance is switched on again, [*] will disappear.
※If the balance is running on batteries and the unit is switched off, the display does not display [*].
The bar graph shows the current load status with respect to the
capacity of the balance. The nearer the [F] mark draws, the smaller
the measurable weight becomes.
※Even when the display currently indicates zero with the tare
subtracted, the weight corresponding to the subtracted tare is
indicated on the bar.

When the balance remains stable, the stability indicator [○] remains
on. If the balance becomes unstable, the stability indicator [○] will disappear.
When a displayed value flickers or the stability mark 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.

5.
When the tare is subtracted, the measurable range is reduced.
Measurable Range = Capacity - Tare Weight
6.
If [] appears when a sample is loaded, the measurable range has been exceeded.
7.
In counting mode or percentage mode, if no sample is stored in memory the indicator will not
change, even when the measurement pan is pressed.
8.
The measurement mode that is activated when the balance is switched on will be the one that was
active when last switched off. For example, if the balance was switched off in counting mode, this
counting mode will be reactivated the next time the balance is switched on.

6. Counting Pieces
To implement piece-counting, the specified samples are loaded on the balance, and their average unit
weight (hereinafter, simply the “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 on to 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.

※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.

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:
(1)
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 “12.
Specifications,” on page 31.
(2)
In the sampling of Operation Step 3, press the Set key 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;
(1)
When the samples to be counted deviate widely in weight or the number of samples
displayed deviates.
(2)
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 you change the sampling number, subsequent sampling will start from the new sampling number.

7. Measuring Percentage
The percentage measurement function operates by weighing an actual sample, selected as the
reference, and saving its weight as the 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.

flashes. If the balance is affected by wind or other vibrations during this process, the saving time
may be prolonged.
2.
If [] appears briefly, it indicates one of the following states:
(1)
The weight of the reference sample is insufficient.
For the limit weight that can be saved (% limit weight), please refer to “12. Specifications,” on
page 31.
(2)
While setting up the reference value in Step 2, the Set key has been pressed while the
samples were loaded on the balance.
※If [] appears, sampling has been interrupted and the sample value being processed
will not be saved.
3.
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.
21
8. Limit Function
The limit function judges measurements according to a limit value saved in the balance.
The function shows the judgement result by displaying the [] mark as either HI (excessive), OK
(appropriate), or LO (insufficient). This function is very useful when discriminating between conforming
and nonconforming articles. It is also useful when measuring a given constant quantity consecutively, in
conjunction with a range of reference weights defined by upper- and lower-limit values.
This function can be used in weight mode, counting mode, or percentage mode.
Limit value input methods
Either of the following two methods can be used in the different modes:
(1)
Actual quantity setup method ........ An actual sample is loaded on the balance and its weight
saved as the limit value.
(2)
Numeric value setup method ......... The limit value is entered with a key stroke.
※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.
Indication of judgement result
The [] mark lights up as either HI, OK, or LO on the left side of the display, indicating the result of
judgement.

9. Calibrating the Balance
Since electronic balances are affected by gravity gravitational acceleration, they produce different
values in various locations. Therefore, before use, balances must be calibrated at the location where
they are installed. Calibration is also required after long periods without use, or if a balance begins to
produce inaccurate values.
Calibration of a balance, or “span adjustment,” is required to produce accurate measurements.
※ Span adjustment should be performed with the balance installed perfectly level and without any load
on the measurement pan.

☆ Key Points of the Procedure ☆
1.
Pressing the Function key in Step 2 interrupts the span adjustment and returns you to the original
measurement mode.
2.
The calibration weight used for span adjustment should be heavier than half the capacity of the
balance.
To implement a calibration as precisely as possible, use a weight close to the capacity of the
balance.
※ Calibration weights can be ordered from Shinko. For ordering information, please contact
Shinko.
3.
If problems arise during span adjustments, one or more of the following error messages will
appear:
(1)
[]: The calibration weight exceeds the capacity of the balance.
(2)
[]: The calibration weight is less than half the capacity of the balance.
(3)
[]: The difference between before and after calibration values is too large (1.0%
or more).
※If error messages are displayed, calibration cannot take place.
Check the weight and re-calibrate. If the same error continues after repeated calibrations using
the correct weight, please contact our Marketing Division or Technical Service Division.

10. Operating the Balance with the Battery
This function can be used only when the balance is battery-operated.
10.1
Specifications
• Built-in nickel-cadmium battery
• Charging time: Approximately 12 hours
• Drive time:
Approximately 32 continuous hours
• Number of charge/discharge cycles: 300 or more
10.2
Charging Method
※While the balance is battery-operated, [
] stays on. The indicator flashes [
] (charging
], charge the battery by
required) when battery capacity decreases. If the balance flashes [
following these steps:
(1)
Connect the dedicated AC adapter to the balance.
(2)
Turn the balance off.
(3)
Charging takes approximately 12 hours, with power switched off. Charging the battery longer than
12 hours decreases battery life.
10.3
User Precautions
1.
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 will also decrease battery life.
2.
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.
3.
When the battery displays no indication, or an indication disappears 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.
4.
Charging the battery while [
!
] is displayed reduces battery life.
Cautions To operate the balance safely, observe the following (failure to do so could result in
malfunctions, breakage, burst batteries, or fire):
1.
Do not disassemble or modify the battery. Do not reverse the balance connection or short-circuit
the positive and negative polarities of the balance.
2.
Use only the supplied AC adaptor.
3.
Do not incinerate used batteries. Dispose as hazardous material only.
