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 “6. Calibration”)
Balance location
To measure correctly, to keep the balance in good conditions, and to prevent hazards, observe the following
• Do not install the balance in locations that are subject to dust, breeze, vibration, large temperature fluctuations, condensation or that may have a magnetic field.
• 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 (OP09-i 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
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.
• Be sure to charge the battery pack before using it for the first time.

5-1. Turning the power ON and OFF
1. Press the ON/OFF key to turn the power ON.
All the display symbols are displayed as shown above. (About units: Only the units available illuminate.)
When the weighing value internally becomes stable, the display turns off except for a weighing unit and a decimal point.
The balance waits for the weighing data to become stable, and zero will be shown 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 is 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 value changes more than 4 display digits or any key operation is done. When the weight data becomes and stays stable for some time, it will automatically turn off. There is also a setting that will make the backlight always stay 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 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 on different models. For details, see “13. Specifications”

5-4. Selecting a weighing unit
Press the MODE key to select a unit.
The following sections describe about three common units: g (gram mode), pcs (counting mode), and % (percent mode).
5-5. Basic operation
1. Select a weighing unit.
2. When the display doesn’t show zero, press the RE-ZERO key to set the display to zero.
3. When using a tare (container), place the container on the weighing pan, and press the RE-ZERO key to set the display to zero.
4. Place the object to be weighed on the pan or in the container. Wait for the stability mark ( o ) to be displayed and read the value.
5. Remove the object from the pan.
• Note The RE-ZERO key will zero the balance if the weight is within ±2% of the weighing capacity around the power-on zero point. The ZERO mark turns on. When the weight exceeds +2% of the weighing capacity, it will be subtracted to zero as a tare weight. In this case the ZERO and NET marks turn on.
Each press of the key switches the units available in the order described on the previous page.

5-6. Weighing range for the E series
• The EW-i series have three weighing ranges, and the display shows which range the weight value belongs to with the mark R1, R2 or R3.
• There is a function setting to select how the weighing range changes.
• Select from automatic range (rng 1), manual range (rng 0) or fixed range (rng 2 to 4).
Operation
Automatic range
When the weight value exceeds the maximum value of a range, the weig hing range changes automatically from a fine to a coarser weighing range.
• When there is nothing on the weighing pan and the display shows zero with the ZERO mark, the weighing range changes from the coarse to the fine range.
• When the balance is in range 2 or 3 and there is nothing on the weighing
pan, press the RE ZERO key to re zero the display. The balance will return
to the fine range and gross weight zero will be displayed with the zero mark
• When the balance is in the coarse range with an object (container) on the weighing pan press the RE ZERO key to tare the course display. The balance will return to the fine range and net weight zero will be displayed with the zero mark
Manual range
• Press the SAMPLE key when the display shows a weight value (neither counting nor % display). The weighing range changes to a coarser range at any load.
• Press the SAMPLE key to change from a coarser to the fine 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 coarse range the object (container) is tared and the display will return to the fine range in a net weighing mode
• When in range 2 or 3 and a weight less than 2% of capacity is on the weighing pan the display will be re zero when the RE ZERO key is pressed, remaining in the same range and in gross weighing mode. Press the SAMPLE key to change to the fine range if required.
Fixed range
• The weighing range is fixed. Set the function to the weighing range according to the purpose.
