The removable breeze break makes it easy to clean the inside of the weighing chamber.
A self check function is included for automatically evaluating repeatability performance without a weight.
The BA-T series can automatically perform sensitivity adjustment with the internal weight. (Automatic
sensitivity adjustment)
(Temperature change, set time, fixed time interval [interval time])
When performing the sensitivity adjustment/calibration test, etc. for the balance, the output
corresponding to GLP/GMP, etc. can be output.
Using a printer (sold separately), it is possible to record the sensitivity adjustment/calibration test
results.
GLP :Good Laboratory Practice. Standards for implementing safety tests for drugs and medicines.
GMP :Good Manufacturing Practice. Rules for manufacturing and quality control.
The clock built into the balance allows you to output the weighing value with the date and time.
(The clock settings can be restricted so that only the Administrator can change them. [Password
function])
The BA-T series comes standard with the underhook for weighing magnetic materials.
Four different applications are available.
Normal weighing, counting mode, percent weighing, minimum weight alert function.
BA-6DTE, BA-225DTE and BA-125DTE have the smart range function as standard. This function allows
for weighing with the precision range after subtracting the tare within the weighing capacity.
The readability of precision range for BA-6DTE is 1 μg.
The readability of precision range for BA-225DTE and BA-125DTE is 10 μg.
With the password function, the sensitivity adjustment of the balance and the operation of changing the

Installation considerations, preparation and precautions
Prepare the following installation conditions in order to bring out the full performance of the balance.
Note that the installation environment needs to be taken into consideration for the highly sensitive BA-
6TE / BA-6DTE.
Install the balance in an environment where the temperature and relative humidity are not excessive.
The best operating temperature is about 20°C ±2°C at about 45% to 60% relative humidity.
Install the balance where it is free of dust.
The weighing table should be solid. (An anti-vibration table or stone table is ideal)
We recommend using an anti-vibration table (AD-1671) for BA-6TE.
It is advisable to install the display unit in a location other than on the anti-vibration table so that errors
due to tilt that occurs when operating the switches of the balance on the anti-vibration table can be
avoided.
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. Avoid breezes and drafts in the
room.
You can reduce the influence of breezes and drafts by using an AD-1672/AD-1672A (large size) or AD-
1676 (medium size) tabletop breeze break.
Install the balance where it is not exposed to direct sunlight.
Install the balance away from equipment which produces magnetic fields.
Level the weighing unit with the leveling feet and bubble spirit level. Refer to “2.3.1. 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-6TE/BA-
6DTE, 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 how to adjust sensitivity, refer to
“10. [Sensitivity Adjustment] Screen”.
Do not install the balance where flammable or corrosive gas is present.
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.

Precautions during use for more accurate weighing
For precise and accurate weighing, please take notice of the
following.
Weighing errors may occur due to the influence of static
electricity. Note that if the ambient humidity drops below 45% RH
insulators such as plastics are liable to have static electricity.
Ground the balance and perform the following as needed.
A DC type ionizer that produces no currents of air is available for
the BA-T series balances. Refer to “22. Ionizer (AX-ION-25)” and
remove static electricity from the charged sample directly.
Increase the relative humidity at the place where the
balance is installed.
Weigh the sample in a conductive metal container or the
like.
Wipe off charged materials such as plastic with a damp
cloth to suppress static electricity.
Influence of magnetism may cause weighing errors.
When measuring magnetic materials (iron, etc.), keep the
sample away from the balance main body by means such as
underhook weighing.
Place the sample in the center of the weighing pan.
Weighing errors may occur if there is a difference between the
ambient temperature and temperature of the sample (and the
container). For example, when the room temperature is 20 °C,
convection occurs around a Petri dish or watch glass that is
40 °C and the balance displays a value lighter than the actual
weight. Before weighing the sample and the container, try to
acclimatize them to the ambient temperature.
Perform the weighing operation carefully and quickly. If
measurement takes a long time, error-inducing factors will
increase due to changes in temperature and humidity in the
weighing chamber, air turbulence or reaction/humidity absorption
by the sample.
Do not leave the sample on the weighing pan for an extended
period of time. If a sample is left on the weighing pan for a long
time, the measured value will change due to deviation from the
zero point caused by environmental changes or due to creep
phenomenon.

When placing a sample on the weighing pan, do not drop it, or do not place a sample greater than the
balance weighing capacity. In addition, place the sample in the center of the pan.
With the highly sensitive BA-6TE, the weighing value may fluctuate after the stabilization indicator lights
up. It is advisable to set a certain reading time (10 seconds, etc.) after the stabilization indicator lights
up and read the value.

17
For weighing where impurities will be a problem, it is advisable to prepare samples outside the
weighing chamber in order to prevent the substance from scattering inside the weighing chamber.
When pressing the touch screen or keys, do not press with a sharp object such as a pen. Instead,
press the center of the key with your finger.
Be sure to press the RE-ZERO button before weighing in order to eliminate measurement
errors.
Measurement results include error from air buoyancy. The buoyancy of air varies depending on the
sample volume, atmospheric pressure, temperature, and humidity. Correct the buoyancy for the most
precise measurement.
Prevent foreign substances such as powder, liquid, and metal pieces from entering the balance.
Precautions after use
Avoid mechanical shock to the balance.
Do not disassemble the balance.
Do not use any strong organic solvents to clean the balance. Clean the balance with a lint free cloth that
is moistened with a mild detergent.
Prevent foreign substances such as powder, liquid and metal pieces from entering the balance.
Caution on the power supply
Be sure to warm up the balance before use for at least an hour, or at least four hours for BA-6TE/BA-
6DTE, with the AC adapter connected to the power supply.
The balance is constantly provided with power as long as the AC adapter is connected.
The balance is not adversely affected in this state.
It is advisable to always keep the balance in this state for accurate weighing.
Be sure to keep the BA-6TE/BA-6DTE always in a state where power is being supplied.
