• Install the balance where it is free of dust.
• The weighing table should be solid. (An anti-vibration table or stone table is ideal)
• Place the balance on a horizontal table, and make sure that it is not tilted.
• Install the balance in a stable location, avoiding vibration and shock. Corners of rooms on the first floor are best, as they are less prone to vibration.
• Install the balance where it is not affected by heaters or air conditioners.
• Install the balance where it is not exposed to direct sunlight.
• Install the balance away from equipment which produces  magnetic fields.
• Level the balance with the leveling feet and bubble spirit level.
• Refer to “3.1. How to adjust the level of the balance”.
• Be sure to warm up the balance before use for at least an hour, or at least four hours for BA-6E / BA-6DE, with the AC adapter connected to the power supply.
• Adjust the sensitivity of the balance before using it for the first time or after having moved it to another location so that accurate weighing can be performed. For details, refer to the detailed instruction manual listed in “1.1. Detailed manuals”.

How to adjust the level of the balance

• Level the balance by adjusting the leveling feet so that the bubble of the bubble spirit level is centered in the red circle.

• When the bubble is off to the left.
  Turn the leveling foot on the front right in the clockwise direction.

• When the bubble is off to the right.
  Turn the leveling foot on the front left in the clockwise direction.

• When the bubble is off to the backward  position.
  Turn both leveling feet on the front in the clockwise direction at the same time.

• When the bubble is off to the forward  position.
  Turn both leveling feet on the front in the counter clockwise direction at the same time.

• Error Displays (Error Codes)

Other display

• The automatic sensitivity adjustment notice (the indicator blinking) indicates that the automatic sensitivity adjustment will start.
• If the balance is not used for a certain period of time with this indicator blinking, the balance automatically performs sensitivity adjustment using the internal weight. (The blinking period depends on the operating environment.)
• Although it is possible to continue using the balance even while this indicator is blinking, use after sensitivity adjustment is completed is advisable in order to maintain the weighing accuracy.

Ionizer (AX-ION-25)

The AX-ION-25 ionizer comes standard with the BA-6E / BA-6DE. The ionizer removes static electricity by irradiating the target object with positive or negative ions, which are generated from four discharge electrodes by DC corona discharge. Ordinarily, insulators such as powders, filters, and weighing paper tend to be charged when the humidity is 45% RH or less, and an error of a few milligrams may occur during weighing. By removing static from the weighing object with the ionizer, it is possible to eliminate the error in the weighing value due to charging, and correct weighing can be performed. For details, refer to the separate instruction manual in “1.1. Detailed manuals”.

Using the ionizer

• Step 1. Make sure that the AC adapter of the balance is not connected, and then connect the balance  and the ionizer (as noted in “2. Assembly and Installation”).
• Step 2. Connect the AC adapter, plug it in, and then turn on the power. The power lamp of the ionizer  lights up.
• Step 3. Place the target object within the effective range of static elimination.
• Step 4. Hold your hand over the IR sensor (touchless infrared proximity sensor) on the front of the ionizer to start static elimination. The ION lamp indicating that static elimination is in progress lights up.
• Step 5. Refer to the figure below for the effective range of static elimination, and perform static elimination. At factory setting, when 3 seconds have passed from the start of static elimination, the ION lamp indicating that static elimination is in progress turns off and static elimination stops.
