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 cordlessoperation.

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 displayedwith the ZERO mark (power-on zero).
The range for power-on zero is within ±10% of the weighing capacity around thecalibrated 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 isdisplayed for approximately 5 minutes. See “8-5. Function list” andset 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 thatthe 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:
Pound

Ounce (avoir)
Percent mode

Troy ounce
Counting mode
Metric carat
Gram

Momme
Pennyweight
Tael

Grain

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”

 NoteIt is possible to store only the units that will be actually used fromthe units available. It is also possible to specify the display unit thatwill be shown first when the power is switched ON. For details, see“8-4. Storing weighing units”.
