1. INTRODUCTION
This manual describes how this balance works and how to get the most out of
it in terms of performance.
The EK-i and EW-i series balances have the following features:
The EK-i series are high resolution type electronic balances having a resolution of
1/6,000 ~ 1/60,000.
The EW-i series are triple range balances and each range has a resolution of
1/3,000.
The balance has a counting function, % function and a comparator function.
The backlight LCD will help with use in a dimly lighted place.
The standard RS-232C serial interface can be connected to a printer or personal
computer.
Using the serial interface, Good Laboratory Practice (GLP) data can be output.
The optional rechargeable battery pack (OP-09) is easy to install for cordless
operation.

4. SETTING UP
4-1. Setting up your balance
1. Place the weighing pan on the main unit as shown on the previous page.
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 the rechargeable battery pack (OP-09:
Optional item) is available.
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 EK/EW-i.
When using the rechargeable battery pack (OP-09)
Insert the rechargeable battery pack into the main unit.
The balance can be used continuously for about 9 hours using the battery pack.
If “Lb0” is displayed when using the battery pack, immediately stop
using it, and recharge the battery pack or use the AC adapter.
See “11-3 OP-09 Rechargeable battery pack”, for instructions to
install and charge the battery pack.
Be sure to charge the battery pack before using it for the first time.

5. OPERATION
5-1. Turning the power ON and OFF
1. Press the ON/OFF key to turn the power ON.
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 weight data to become stable, and zero will be displayed
with the ZERO mark (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 mark and the ZERO mark turn on.
2. Pressing the ON/OFF key again, and the power will be switched OFF.
Auto-power off function
It is possible to have the power automatically switched OFF, if zero is
displayed for approximately 5 minutes. See “8-5. Function list” and
set the function “
poff
”.
5-2. LCD backlight
The LCD backlight will turn on when the weight data changes more than 4 display
digits 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”.
7
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:
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, while skipping the units that are not available.
Some units are not available for higher or lower capacity models. For details, see “13.
SPECIFICATIONS”
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”.

to 4).
Operation
Function setting Operation
rng 1
Automatic range
When the weight value exceeds the maximum value of
the range, the weighing range changes automatically
from a lower to a higher weighing range.
When there is nothing on the weighing pan and the
display shows zero with the ZERO mark, the weighing
range changes from a higher to the lowest range.
When the RE-ZERO key is pressed in a higher range,
the balance will be tared to zero and the weighing range
changes to the lowest range.

Manual range
Press the SAMPLE key when the display shows a
weight value (neither counting nor % display). The
weighing range changes to a higher range at any load.
Press the SAMPLE key to change from a higher to the
lowest range, when there is nothing on the weighing pan
and the display shows zero with the ZERO mark.
When the RE-ZERO key is pressed in a higher range,
the balance will be tared to zero and the weighing
range changes to the lowest range. If the weight of the
object is not more than 2% of the weighing capacity, the
RE-ZERO key doesn’t tare, but zeroes the balance
and the weighing range doesn’t change.
Press the SAMPLE key to change the weighing range
at zero display.

OP-04 Installation
1. Remove the cover of the option slot on the rear of balance by pressing and lowering
it down.
2. Insert the option into the slot and secure it with the screws attached.
11-2. OP-07 Underhook assembly
By attaching the underhook assembly to the bottom of the balance, large objects that
are difficult to load on the weighing pan can be weighed in suspension, and the
specific gravity of objects may be measured.
OP-07 is available for use with the EK-6000i / 12Ki / 4100i / 6100i and EW-12Ki
balances only.
The calibration with a weight being hung on the hook is required for
an accurate weighing.
OP-07 Installation
Remove the cover on the bottom of the balance, and screw the underhook assembly
into the mounting hole.
32
11-3. OP-09 Rechargeable battery pack (Ni-MH)
By installing the rechargeable battery pack (Ni-MH) into the balance, cordless
operation can be carried out for approximately 9 hours (used with the LCD backlight
off).
OP-09 cannot be used together with OP-04.
The battery life will vary depending on how the balance is used,
ambient temperature and so on.
Charging the battery pack
Connect the AC adapter to the balance and turn the power off, then charging starts. It
will take approximately 15 hours to reach full charge.
If “
lb0
” is displayed when using the battery pack, immediately stop
using it, and recharge the battery pack or use the AC adapter.
Charge the battery pack at a temperature between 0°C (32°F) and
40°C (104°F).
Do not charge too long. Overcharging will reduce the life of the
batteries.
Be sure to charge the battery pack when using for the first time or if
it has not been used for a long time (more than one month).
Recharging two or three times may be needed to reach full charge.
Be sure to use only the AC adapter that is provided with the EK/EW-i
balance.
OP-09 Installation
See the OP-04 installation.
11-4. OP-12 Carrying case
OP-12 is available for the convenience of carrying the balance by hand. However, note
that because these balances are precision equipment, they will not be able to
withstand excessive shock, such as being dropped.
33
12. MAINTENANCE
12-1. Notes on maintenance
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 lint free cloth
dampened with a mild detergent.
12-2. Error codes
Overload error
Warning to indicate that an object beyond the balance
capacity has been placed on the pan. Remove the object
from the pan.
Warning to indicate that the balance detects an
unexpected load. Remove all objects from the pan or
check that the weighing pan is correctly installed.
Range over notice
This will be shown if the weight sensor receives strong
force upward. Check if there is anything sandwiched
around the weighing pan. There is a possibility that the
weight sensor itself may have a failure.
Unit / 100% weight error
The unit / 100% weight is too light in the counting / %
mode.
Sample quantity notice
When sample weight is light and the counting error could
become large, the balance will prompt you to use a
larger number of samples. Place the displayed number of
samples on the pan and press the PRINT key to store
the unit weight.
Note: Pressing the PRINT key without adding
samples may reduce counting accuracy.
Starting from the 100 samples, 100 - may
be displayed when the sample weight is light.
This is for your notice and press the PRINT
key without adding any samples.
When “aCai 0” (ACAI disabled) or “Umin 2” is
set, this notice is not shown.
