IMPORTANT
PREFACE
Thank you for purchasing an SJP-CE Series electronic balance. This is a precision instrument
equipped with exacting mechanisms in a compact body. The SJP-CE 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. Basic Operations
3.1 Installation
1 Positioning the measurement pan
First, mount the pan base on the
main unit of the balance and place
the measurement pan on top of it.
2 Securing the exact level of the balance
Position of air bubble
in the level
Turn the adjusters until the bubble
rests in the center of the red circle
on the level.
<Caution>
Use caution when operating the
adjusters on the square-pan type to
prevent them from lifting up.
3 Connecting the AC adapter
Connect the AC adapter to the
balance, as illustrated at left.
※Take 5 minutes before operation.

3.2 Operation Check
1 Turning on the power
*
When the balance has the AC
adapter connected, it displays [＊].
Pressing the On/Off key
The display section lights up, and
the balance is ready for operation.
2 Checking the display Check to see if the display has any
missing indications or unlit parts.
A few seconds after startup, the
indication is reset to zero.
※At the same time, the back-light is
on. ( The back light is always on
during power on )
（When the balance is sealed）
After every segment lights,[
] appears Adjust Zero point and
Weight display appears.
If something is loaded, the display
does not change after [] In
this case, remove the load.
3 Switching the measurement mode
Press the Function key.
Each time the key is pressed, the
unit of measurement changes, as
indicated.
※The balance is shipped from the
factory with the following switching
sequence: [g] →[ct] →[Pcs] →
[%] →[g] →· · ·
※[ct] is not available for
SJP-6200CE & SJP-12KCE
4 Verifying changes in the read-out indicator
Press the measurement pan lightly
and make sure that the read-out
indicator changes.
Also, ensure that the read-out
indicator is reset to zero when you
release your hand.
5 Turn off the power

3.3 Operation for Tare Subtraction
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.

5 Adding samples to be measured
The balance indicates only the

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.

☆Key Points of the Procedure ☆
The following applies equally to all the measurement modes for weight measurement, counting, and
percentages.
1. 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
[＊].
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
0・|・|・| F
g
0・|・|・| F
○ g
4. When the read-out indicator is reset to zero or the tare is subtracted, the balance indicates zero
this way: [→0 ←]. If the tare is subtracted, the indicator reads as follows: [NET].
* If the indication
deviates from the
true zero point by
1/4 of a graduation
or less, [→0 ←]
disappears.
* If the tare is
subtracted, the
balance indicates
zero, and [NET]
lights up.
→0← 0|||F
g
→0← 0・|・| | F NET
g
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.
9. To print data on the balance, set “Output Control ()” to [], [], [], or [], so that only
stable data will be printed (see “4.3 Interface Section” on page 14).

5. Switching Function for Units of Measurement
Pressing the Function key allows the user to switch the unit of measurement to [g], [ct], [%], and so
on.
Up to five different units can be registered for use only when the function key is properly set on a
balance for which the balance is not sealed.

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.

☆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.
6. The units can be set only on the balance is not sealed.
7. When units other than
[g] or [ct] is selected and the power is turned off, [g]is automatically
selected the next time the power is turned on. ( under the balance is sealed.)

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. Sampling Counting Pieces

※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.
