PREFACE
Thank you for purchasing an SA/CA-E Series electronic balance. This is a precision instrument
equipped with exacting mechanisms in a compact body. 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.
With dry cell operation, you can use the balance where no power supply is available.

1 Place the tare (container) on the balance. As you place the tare, the balance
indicates its weight.
2 Reset read-out indication to zero. Press the Zero/Tare key.
The tare is subtracted and the
balance indicates zero.
3 Load the sample to be weighed. The balance will now indicate only
the weight of the sample loaded in
the tare.
☆Weighing only the weight of an added sample
4 Resetting the indication to zero Press the Zero/Tare key.
The total weight of the sample
loaded on the measurement pan is
indicated as zero.
5 Adding samples to be measured The balance indicates only the
weight of an added sample.
When the weight (of a sample)
currently loaded on the
measurement pan is reset to zero
with the Zero/Tare key, as
mentioned above, only the weight of
the sample will be measured.

1. After the balance is switched off, there is still enough current to display [＊]. This indicates that the
AC adaptor 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 [＊].
2. 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.
3. 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.
Unstable Stable
4. When the read-out indicator is reset to zero or the tare is subtracted, the balance indicates zero this
way: [→0 ←].
* If the indication
deviates from the
true zero point by 1/4
of a graduation or
less, [→0 ←]
disappears.
* If zero is set or the
tare is subtracted,
the balance indicates
zero, and [→0 ←]
lights up.
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. The measurement unit 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 gram, this gram unit
will be reactivated the next time the balance is switched on.

5.2 Setup of Units of Measurement
When values [ ] to [ ] are entered prior to use, the desired unit of measurement to be
displayed can be chosen simply by pressing the Function key. For more information on the units of
measurement that can be set here, please refer to “4.2 Description of Functions” on page 13.
Example:To change the default factory settings to pound units, use [ ] in the factory
settings.
1 Display the function item [ ] Press and hold down the Function
key.
Release the key as [ ] appears
on the display.
The function setup mode is now

☆Key Points of the Procedure ☆
☆☆
☆
1. When set values are entered in the function items [ ] to [ ] prior to use, the desired
unit of measurement to be displayed can be selected simply pressing the Function key. For
more information on the units of measurement that can be set, please refer to “4.2 Description of
Functions,” on page 13.
2. The units are displayed in the same sequence as the settings made from [ ] to [ ].
3. If [ ] is set, no unit of measurement will be displayed, even when units of measurement are set
in subsequent items.
4. [ ] cannot be set in [ ].
5. If the same unit of measurement is set multiple times, the second time (and all subsequent times)
the unit(s) occurs, it will be ignored when the display switches.
16 6. Calibrating the Balance
g
gg
g
g

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.
※Always perform calibrations without samples loaded on the measurement pan.
1 Activating the span adjustment function
Pressed
continuously
Key released
Press and hold down the Function
key.
Release the key when the display
changes from [ ] to [ ].
2 Starting the span adjustment
Release
simultaneously.
Press the Function key while
holding down the Zero/Tare key.
Press the Function key while holding
down the Zero/Tare key, then
release both keys simultaneously. The
display flashes [ ], indicating
that zero-point calibration is underway.
3 Zero calibration Zero-point calibration is finished when
the display changes to [ ].
Proceed to the calibration of the
capacity point.
17
Calibrating the Balance (cont.)
4 Calibrating the capacity point Open the windshield. Load the
①②

calibration weight in the center of the
balance. Close the windshield.
The display flashes, indicating that
capacity point calibration is in progress.
5 Terminating the span adjustment When the calibration of the capacity
point is finished, the original
measurement mode is restored.
☆
☆☆
☆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).
4. The windshield should be opened and closed politely.
※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.
