1. INTRODUCTION
This manual describes how this balance works and how to get the most out of
it in terms of performance.
EJ series balances have the following features:
The EJ series are high-resolution type electronic balances having a display
resolution of 1/12,000 ~ 1/60,000.
The balance has a counting function, % function and a comparator function.
The backlight LCD will help with use in a dimly lighted place.
The balance can be operated with an AC adapter, or 4 x “AA” size dry-cell
batteries for cordless operation.
The optional RS-232C serial interface can be connected with a printer or personal
computer, and Good Laboratory Practice (GLP) data can be obtained.
The optional USB interface is available to connect with a personal computer
easily.

4. SETTING UP
4-1. Setting up your balance
1. Place the weighing pan on the main unit as shown in “2. UNPACKING”.
2. Adjust the level of the balance using the leveling feet. Use the spirit level to confirm.
The bubble should be in the center of the circle.
3. Calibrate your balance before use. (See “7. CALIBRATION”)
Balance location
To measure correctly, to keep the balance in good condition, and to prevent hazards,
observe the following:
Do not install the balance in locations that are subject to excessive dust, breezes,
vibration, large temperature fluctuations, condensation, or that may have
magnetic fields.
Do not install the balance on a surface that is soft or that may cause the balance
level to shift.
Do not install the balance in direct sunshine.
Do not install the balance near heaters or air conditioners.
Do not use an unstable AC power source.
Do not install the balance in a place where combustible or corrosive gases may exist.
Allow the balance to reach equilibrium with the ambient temperature before use.
Switch the power ON at least half an hour before use so that the balance can
warm up.
When the balance is installed for the first time, or the balance has been moved,
carry out calibration as described in “7. CALIBRATION”
4-2. Power source
For the power source, the AC adapter or 4 x “AA” size dry-cell batteries can be used.
When using the AC adapter
Use a stable power source. To use the AC adapter,
insert the AC adapter plug into the AC adapter jack
on the rear side of the EJ.
When using the dry-cell batteries
Prepare 4 x AA size (LR6 / R6P) dry cell batteries. The batteries are not included in the
product,
CAUTION
Take great care of the polarity of batteries. The polarity marks are shown in the
battery box.
Replace used batteries with four new ones when “lb0” is displayed.
Do not mix used and new batteries. Do not mix the battery type. It may cause
damage to the batteries and the balance.
The battery life depends on the ambient temperature, how to use and so on.
AC adapter jack
5
Remove batteries when the balance is not to be used for a long time. They may
leak and cause damage to the balance.
Damage due to battery leakage is not covered by the warranty.
Installing batteries
1. Turn off the balance and disconnect the AC adapter if used.
2. Slide the battery cover off.
3. Push the battery box up to unhook and pull it out.
4. Insert new four batteries (LR6 / R6P / AA size) into the
battery box, taking extreme care of the polarities.
5. Push the battery box into the balance as before.
6. Attach the battery cover.

All of the symbols are displayed as shown above.
(About units: Only the units available will be displayed.)
The display turns off except for a weighing unit and the decimal point.
The balance waits for the weighing data to become stable, and zero will be
displayed with the ZERO indicator (power-on zero).
The range for power-on zero is within ±10% of the weighing capacity around the
calibrated zero point.
If the power is switched ON while there is a load beyond this range, the balance will
be tared to zero and the NET indicator and the ZERO indicator turn on.

5-2. LCD backlight
The LCD backlight will turn on when the weight value changes more than 4d (4 x min.
display division) or any key operation is done. When the weight data becomes and
stays stable for some moment, the backlight will automatically turn off. There is also a
setting that the backlight is always on or off. For details, see the function setting “ltUp”
of “Function list”.

5-3. Units
The most common unit of weight used around the world is the gram, but there is often
a need to shift to alternative units specific to the country where the balance is used or
to select modes such as counting or percent.
The units and the order they appear in the display are as follows:
Ounce (avoir)
Percent mode
Counting mode
Gram
Density
(specific gravity)
Among the units, those available for the user have been set at the factory before
shipping.
The unit can be selected in the function setting mode. The order of the units available
is the same as above.
Note
It is possible to store only the units that will be actually used from
the units available. It is also possible to specify the display unit that
will be shown first when the power is switched ON. For details, see
“8-4. Storing weighing units”.

acceleration value of the area where the calibration using a weight is
to be done, and calibrate the balance according to the procedure
above. See the next section to set the value.

7-2. Gravity acceleration correction
When the balance is first used or has been moved to a different place, it should be
calibrated using a calibration weight.
But if the calibration weight cannot be prepared, the gravity acceleration correction will
compensate the balance. Change the gravity acceleration value of the balance to the
value of the area where the balance will be used. See the gravity acceleration map
appended to the end of this manual.
Note
Gravity acceleration correction is not required when the balance is
calibrated using a calibration weight at the place where the balance
is to be used.
1. Press and hold the calibration (CAL) switch until
Cal appears, and release the switch.
2. The balance displays Cal 0 .
3. Press the RE-ZERO key.

The next output can be obtained after the display returns below +4d.
Auto-print mode B
Set the function “prt 3”.
The balance transmits the weighing data when the display is stable (the STABLE

9-3. EJ-07 / EJ-08 Underhook
By attaching the underhook to the bottom of the balance, large objects that are difficult
to load on the weighing pan can be weighed, and the density (specific gravity) of
objects may be measured. Refer to the “9-6. EJ-13 Density Determination Kit” for the
information about the density measurement.
EJ-07 is for use with the EJ-3000 / EJ-4100 / EJ-6100.
EJ-08 is for use with the EJ-1500 / EJ-2000.
The calibration with a weight being hung on the hook is required for
an accurate weighing.
EJ-07 / EJ-08 Installation
Open the cap on the bottom of the
balance, and screw the underhook
into the mounting hole.
Caution
Do not apply excessive force to the underhook.
When not in use, remove the underhook and attach the cap to prevent dust
from getting into the balance.

Density (specific gravity) measurement
The density of a liquid can be changed and there are two ways of setting. One is to
set the water temperature and the other is to set density value directly.
The factory setting for density of a liquid is 25 °C as water temperature (the density
value ρ = 0.99704 (g/cm
The density (specific gravity) is calculated by the following formula.
S = X ρ S: Density (specific gravity) of a sample
A: Weight in air
B: Weight in liquid
ρ: Density of liquid (water)
The result is shown with two decimal places.

RS-232C interface.
• The result of calibration (“Calibration report”)
• The result of calibration test (“Calibration test report”)
• The “Title block” and “End block” for GLP data
The GLP output format includes the balance manufacturer name, model number,

Do not disassemble the balance. Contact your local A&D dealer if your
balance needs service or repair.
Please use the original package for transportation.
Do not use organic solvents to clean the balance. Use a warm lint free cloth
dampened with a mild detergent.
To clean around the pan support, refer to the drawings below.
