Introduction

Thank you for purchasing A&D’s electronic balance.
Please read this instruction manual carefully to understand and make full use of the BA series
analytical balance.
Caution. Operations may differ depending on the software version of your balance.
For confirmation of the software version of the balance, refer to “28. Checking the Software
Version of the Balance”.

Features
Equipped with the breeze break auto doors that can be opened and closed without touching them.
The removable glass breeze break makes it easy to clean the inside of the weighing chamber.
Equipped with a data memory function to store weighing values, sensitivity adjustment records,
calibration test results, and multiple unit weights (mass per sample in counting mode). (For weighing
values, up to 200 values can be stored.)
The BA series can automatically perform sensitivity adjustment with the internal weight. (Automatic
sensitivity adjustment)(Temperature change, set time, fixed time interval [interval time])
When performing sensitivity adjustment, calibration test, etc., 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 function built into the balance allows you to output the weighing value with the date andtime. (The clock settings can be restricted so that only the Administrator can change them.
[Password function])
The BA series comes standard with the underhook for weighing magnetic materials.
Multiple units of measure are available, including the most common units used around the world.
BA-6DE/BA-225D/BA-125D has the smart range function as standard. This function allows forweighing with the precision range after subtracting the tare within the weighing capacity.
The readability of precision range for BA-6DE is 1 μg.
The readability of precision range for BA-225D/BA-125D is10 μg.
With the password function, the use of the balance and the operation of changing the function table
can be restricted.
With the key lock function, the key operation can be disabled and the balance can be operated only
by a command from an external device.
RS-232C and USB interfaces for outputting the weighing value and data of the balance are equipped
as standard. Windows Communication Tools Software (WinCT) makes it easy to communicate witha Windows personal computer. The latest version of WinCT is available for download on A&D
website.
The BA-6E and BA-6DE are equipped with a DC type ionizer (static eliminator) that does not
generate wind, and eliminates static electricity from charged objects before weighing in order toreduce errors due to static electricity. The discharge electrode unit of the ionizer can be removed
and can be cleaned and replaced by itself.

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 with the highly sensitive
BA-6E/BA-6DE.
Install the balance in an environment where the temperature and humidity are not excessive. The
best operating temperature is about 20°C ±2°C at about 45% to 60% RH 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.)
Place the balance on a horizontal table, and make sure that it is not tilted.
We recommend using an anti-vibration table (AD-1671) for the BA-6E/BA-6DE.
It is advisable to install the display unit in a location other than on the antivibration table so thaterrors due to tilt that occurs when operating the switches of the balance on the anti-vibration table
can be avoided.
Install the balance in a stable location, avoiding vibration and shock. Corners of rooms on the firstfloor 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 balance with the leveling feet and bubble spirit level. Refer to “2.3.1. How to adjust thelevel 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/BA6DE, 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 toanother location so that accurate weighing can be performed. For details, refer to “7. Sensitivity
Adjustment/Calibration Test”.

CAUTION

Do not install the balance where flammable or corrosive gas is present.

Precautions during use for more accurate weighing
For precise and accurate weighing, please take notice of thefollowing.
Charged sample
Weighing errors may occur due to the influence of static
electricity. Note that if the ambient humidity drops below
Metal case
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 series balances. Refer to “29. 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.
IonizerWipe off charged materials such as plastic with a damp cloth
Groundto suppress static electricity.
Place the sample in the center of the weighing pan.
Influence of magnetism may cause weighing errors. Whenmeasuring magnetic materials (iron, etc.), keep the sample
away from the balance main body by means such as underhook
weighing.
Weighing errors may occur if there is a difference between theambient temperature and temperature of the sample (and thecontainer). For example, when the room temperature is 20 °C,
convection occurs around a Petri dish or watch glass that is
Magnetic
40 °C and the balance displays a value lighter than the actual material
Underhook weighing
weight. Before weighing the sample and the container, try toacclimatize them to the ambient temperature.
Convection
Perform the weighing operation carefully and quickly. If
measurement takes a long time, error-inducing factors will
Room temperature
increase due to changes in temperature and humidity in the
20°C
weighing chamber, air turbulence or reaction/humidity
40°C
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 longtime, the measured value will change due to deviation from thezero point caused by environmental changes or due to creep
No impact shock
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. Place the sample in the center of the weighing pan.
With the highly sensitive BA-6E, the weighing value may
fluctuate after the stabilization indicator lights up. It is advisable
to set a certain reading time (5 seconds, etc.) after thestabilization indicator lights up and read the value.
When pressing keys, do not press with a sharp object such as aGood
Badpen. Instead, press the center of the key with your finger.
Be sure to press the RE-ZERO key before weighing in order to eliminate measurement errors.
For weighing where impurities will be a problem, it is advisable to prepare samples outside theweighing chamber in order to prevent the substance from scattering inside the weighing chamber.
Measurement results include error from air buoyancy. The buoyancy of air varies depending on thesample volume, atmospheric pressure, temperature, and humidity. Correct the buoyancy for themost precise measurement.
Prevent foreign substances such as powder, liquid, and metal pieces from entering the balance.
14

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 cloththat 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-6E/BA6DE, 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-6E/BA-6DE always in a state where power is being supplied.

Counting mode (PCS)This is the mode to determine the number of objects in a sample. Based on the reference sample
unit weight (weight per piece), the balance calculates and displays how many pieces the sample
weight corresponds to. The smaller the variation in the unit weight of sample pieces is, the moreaccurate the count will be. The balance is equipped with the Automatic Counting Accuracy
Improvement (ACAI) function to improve the counting accuracy.
Note.

It is recommended that the unit weight (weight per piece) of the sample should be 0.1 mg or
more.
If there is a large variation in the unit weight of sample pieces, it may not be possible to countaccurately.
If a large error is found in the counting measurement, try a method such as performing ACAI
frequently or multiple measurements.

Selecting the counting mode

Step 1. Press the MODE key to set the unit display to ”

Storing a unit weight“ (pieces).

Step 2. Press the SAMPLE key to enter the unit weight storing mode.
Note that even in the unit weight storing mode, pressing the
MODE key switches to the next mode.
Step 3. Select the number of sample pieces using the SAMPLE
key. (10 pcs  25 pcs  50 pcs  100 pcs  5 pcs)
Note that a greater number of sample pieces at time ofunit weight storing will yield more accurate counting result
since the sample unit weight is usually considered to varyslightly.
Step 4. Place a container on the weighing pan, if necessary.
Press the RE-ZERO key to set the display to. (In this example, the number of sample
pieces to store is set to 25.)
Step 5. Place the displayed number of sample pieces on theweighing pan/container.
Step 6. Press the PRINT key to store the unit weight. The balancedisplays the count. (In this example,
is displayedwhen 25 is set.)
The balance prompts to add more sample pieces if it judgesthat the loaded sample is too light (resulting in large counting
error). Add more sample pieces until the displayed number isreached, and then press the PRINT key again. When the unit
weight is stored correctly, the balance displays the count.
If the balance judges that the sample is too light to be stored
as the unit weight, it displays.
The stored unit weight is stored in nonvolatile memory even
if the power is removed.

Automatic Counting Accuracy Improvement (ACAI)This function automatically improves the counting accuracy each time the numberof sample pieces is increased. (Errors will be reduced as variations in sample
weight are averaged.)
After storing the unit weight in step 6, proceed to step 8 below.

Processing indicator

Step 8. Add a few sample pieces. The processing indicator then turns on.
(Three or more pieces are required in order to prevent errors. The processing indicator does
not turn on if overloaded. Add approximately the same number of sample pieces as
displayed.)
Step 9. Do not touch or move the sample pieces while the processing indicator is blinking. (Theaccuracy is being updated.)
Step 10. The accuracy is updated after the processing indicator turns off. Each time this process isrepeated, the counting accuracy will improve further. The range of ACAI after exceeding 100 is
not predetermined. Add approximately the same number of sample pieces as displayed.
Step 11. Remove all the sample pieces used with ACAI from the weighing pan and start counting work.
Note.
Do not change units during ACAI processing.

Storing unit weights

By using the data memory function, up to 50 unit weights can be stored.

Step 1. Set the "Data memory ()" item of the function table

Impact Shock Detection (ISD) Function

The BA series has a function to detect impact shocks to the mass sensor section and to display the
impact level. (Available with balance software versions: 1.006 or later for the display unit and 1.002
or later for the weighing unit)
By lowering the impact level at the time of loading, it is possible not only to alleviate variation in theweighing value but also to reduce the risk of failure of the mass sensor section.
Especially when incorporating the balance in a production line, etc. and weighing by means such as
an automated system, impact to the sensor may be applied greater than expected. When designing
automatic systems and the like, it is recommended that you minimize the impact level as much as
possible while checking the shock indicator.
The shock indicator has 5 levels from level 0 to level 4.

You can turn off the impact shock detection by setting to/in the function table. Even
if the impact shock detection function is turned off, a record is kept in the balance when there is a shock
impact.
Note□ Impact on the weighing sensor is not only that applied to the weighing pan when loaded, but also
may be impact applied from the table on which the balance is installed. The impact detection function
also works for impact coming from the table.

Recording Impact History
Impacts of impact level 3 or higher are stored on the balance with data and time (up to 50 instances).
When the password lock function is ON (), the login user information is added when outputting
the impact history.
Note□ If data instances exceed 50, the stored data with the lowest impact level will be overwritten.
□ The stored impact history cannot be deleted.
□ Impact data where the balance is not energized (during transport, etc.) is not stored.

Sensitivity Adjustment/Calibration Test

Since the balance's resolution is high, weighing values may change due to gravity and daily
environmental changes. It is necessary to perform sensitivity adjustment with the weight in order tokeep the weighing values from changing even if gravity or the environment changes. It is
recommended that you perform sensitivity adjustment if the balance is installed for the first time or
relocated, or when the weighing values change significantly in daily check, etc.
Sensitivity adjustment means to adjust the weighing value of the balance using the reference weightor internal weight.
Calibration test is to weigh with the reference weight and compare how much the result deviatesfrom the reference value. Note that sensitivity adjustment is not performed in calibration test.

Sensitivity adjustment

Automatic sensitivity adjustment
Adjusts the balance automatically using the internal weight according to ambient temperaturechange, set time or interval time.
Sensitivity adjustment using the internal weight

Calibration test

Calibration test with an external weight
Checks the accuracy of weighing using your external weight and outputs the result.
Note that sensitivity adjustment is not performed.
Calibration test with an internal weight
Checks the accuracy of weighing using the internal weight and outputs the result.
Note that sensitivity adjustment is not performed.

Caution for sensitivity adjustment/calibration test

Do not allow vibration or drafts to affect the balance during sensitivity adjustment or calibration test.
The GLP/GMP (etc.) compliant report can be output in sensitivity adjustment/calibration test. To
output the GLP/GMP compliant report, you need to set “GLP output ()” in the function table andprepare a personal computer or optional printer. A timestamp (clock and calendar) is available for
the GLP output using the clock function of the balance. If the time/date is not correct, adjust theclock by referring to “9.4. Clock and calendar function“ in “9. Function Table”. The calibration test is afunction that is available only when the output of GLP/GMP (etc.) compliant report is set.
By setting "Data memory ()" of the function table, the data of sensitivity adjustment report andcalibration test report can be stored in memory.

This indicator means the balance is measuring sensitivity adjustment data/calibration test data. Do not allow vibration or drafts to affect the balance while
this indicator is displayed.

Automatic sensitivity adjustment
This function automatically adjusts the sensitivity of the balance according to ambient temperaturechange, set time or interval time using the internal weight. It works even when the display is off.
For the automatic sensitivity adjustment mode, “Temperature change ()”, “Set time ()”,
or “Interval time ()” can be set in “Sensitivity adjustment mode ()” of the function table.
For the set time, "Set time 1 () and "Set time 2 ()" are available in the function table.
The Interval time can be set in the range of 0.5 hours to 24 hours in "Interval time ()" of thefunction table.
After sensitivity adjustment, the balance will output the sensitivity adjustment report and store thedata as set in the function table.
For the sensitivity adjustment report output, the GLP/GMP (etc.) compliant report is output as set in"GLP output ()" of the function table.
The data memory function stores the sensitivity adjustment report as set in “Data memory function()” of the function table.
For details, refer to “GLP output ()” and “Data memory function ()” of the function table.
Caution If something is on the weighing pan, the balance itself will judge that it is in use and will not
perform automatic sensitivity adjustment.
The criteria for performing automatic sensitivity adjustment are as follows.
Model
BA-6E/BA-6DE/BA-225/BA-225D/BA-125D

Range
Less than 0.1 g

To maintain the correct sensitivity adjustment of the balance, do not place anything on the weighing
pan while not in use.

Tips

The automatic sensitivity adjustment notice (theindicator blinking) indicatesthat the automatic sensitivity adjustment will start. If the balance is not in use, after
blinking for a while, the balance will start automatic sensitivity adjustment using theinternal weight. (The blinking duration depends on the environment.)

Although it is possible to continue using the balance even while the automatic sensitivity
adjustment notice (theindicator) is blinking, use after sensitivity adjustment is completed isadvisable in order to maintain the weighing accuracy.
"Prohibit automatic sensitivity adjustment" or "Allow automatic sensitivity adjustment" can beselected in the setting described in “8. Function Selection Switch and Initialization”.

Condition ()

Sensitive response to fluctuation of a weighing value
For powder or liquid target weighing, weighing a very light sample, or when work
efficiency is required rather than display stability, set the parameter to be a small value.
When set, FAST is displayed.
Slow response to fluctuation of a weighing value.
To prevent the weighing value from drifting due to vibration or drafts, set the parameterto be a high value. When set, SLOW is displayed.

Stability band width ()

This item is to control the width to regard a weighing value as a stable value. When the fluctuation
range of weighing value within a certain period of time is less than the parameter, the balancedisplays the stabilization indicator and the data can be output (or stored) as set in function table(,, etc.).
This setting influences "auto print mode". The readability being displayed is 1 d.
Example. For the BA-6E, if 0.00001 g display is selected with the SAMPLE key, 0.00001 g is 1 d.
The stabilization indicator will not display if the value is not stable enough, and it will
disappear if there are even slight fluctuations in the weighing value. To perform
weighing with strict judgment, set the parameter to a low value.
The stabilization indicator becomes less responsive to slight fluctuations in theweighing value. To prevent the weighing value from drifting due to factors such as theusage environment, set the parameter to a high value.

Zero tracking ()

This function tracks zero point drift caused by changes in the environment and stabilizes the zero
point. The degree of tracking can be selected from three levels.
If zero is not stable, increase the parameter.

5910. GLP Report and ID Number
Main objectives

The GLP/GMP compliant data can be output to a personal computer or optional printer via the RS232C serial interface.
The GLP/GMP compliant report includes the balance manufacturer (A&D), model name, serial
number, ID number, date, time, and space for signature. For a sensitivity adjustment or calibration
test, the result and the weight used are also included.
The balance can output the following GLP/GMP compliant reports via the RS-232C or USB.
Sensitivity adjustment report(Output for sensitivity adjustment using the internal weight, automatic sensitivity adjustment,sensitivity adjustment using the external weight)
Calibration test report(Output for calibration test using the internal weight or external weight)
Breaks (“title block" and "end block") for easy management of a series of weighing data
By changing the function table, sensitivity adjustment results and calibration test results can be
temporarily stored in data memory and output in batch.
Note.
For details, refer to “11. Data Memory”.
The ID number can be used as an identification number for the balance during maintenance of thebalance.
The ID number is stored in non-volatile memory, even if the AC adapter is removed, and it is valid
until a new registration is made.
For check/adjustment of time/date, refer to “9.4. Clock and calendar function”.
When printing a GLP compliant report with an AD-8127 multi-functional compact printer connectedto the balance, the clock function of the printer can be used to print the time and date. (Function
table). Centralized management using the password lock function on the AD-8127 side iseffective in preventing time and date tampering.
Note.
To output GLP/GMP compliant reports, set the print mode of the AD-8127 to the dump print
mode. If the external key print mode is set for weighing value printing, press and hold the ENT
key of the AD-8127 for 2 seconds to switch between the external key print mode and dump

13. Minimum Weight Alert Function
Minimum weight is the minimum sample weight required to perform correct quantitative analysis
taking the measurement error of the balance used into account. If the sample amount is too small,the proportion of measurement error in the measured value increases, and the reliability of theanalysis result thus may drop.
The minimum weight alert function makes it possible to judge immediately whether the sample
amount meets the set minimum weight.
With this function, “” displays blinking at the top of the unit when the sample amount is less than
the set minimum weight. When the sample amount exceeds the set minimum weight, “” ishidden.
This function can be used only when the unit is "mg".
The minimum weight can be changed in the function table. The factory setting is 0 mg. When the set
value is 0 mg, even if the "Minimum weight alert function ()" of the function table is set to"Enables comparison excluding near zero ()" or "Enables comparison including nearzero ()", the alert is not displayed. Values above the weighing capacity cannot be set asa minimum weight.
There are two types of alert displays: Near zero is within ± 10 d of 0 mg.
“Enables comparison excluding near zero ()““Enables comparison including near zero ()”
CautionWhen a parameter other than "Disables minimum weight alert function ()" is set, the
MODE key is assigned to the minimum weight setting and the unit cannot be changed with the
MODE key. (The unit is fixed to mg.)
To change the unit, disable the minimum weight alert function.
To disable the minimum weight alert function, refer to the procedure in “13.1. Enabling theminimum weight comparison” and set to.

The built-in underhook is used for underhook weighing such as measurement of magnetic materials
and the like.
To use the underhook, open the cap on the bottom of the balance.
Caution
Do not apply excessive force to the underhook part.
Do not open the cap unless necessary. (For protection from dust)
The underhook can be used only in the hanging direction (pulling direction).
If the balance is tilted greatly, attached parts such as the weighing pan will come off. Remove them
before work.
Keep in mind that draft enters the balance easily when the underhook cap is removed, affecting theweighing values.

Repeatability is an index of variation in measured values when the same mass is repeatedly loaded
and unloaded, and is usually expressed as the standard deviation (σn-1). The BA series have aninternal weight.
The repeatability check function uses the internal weight to acquire measurement data 10 times anddisplays the standard deviation. By using this function with the installed balance, repeatability in the
installation environment can be checked.
Example.

"Standard deviation = 10.0 mg" shows that the results of repeated measurements of thesame sample fall within the range of ±10.0 mg with a frequency of about 68%.

Step 1. In weighing mode, press and hold the
SAMPLE key for 4 seconds.

Step 5. Press the CAL key to return to weighing mode.
Note
Consider the result of this function as a reference value because the condition where the internal
weight of the balance (BA-6E/BA-6DE with about 5 g or BA-225D/ BA-225/BA-125D with about 100g) is used is different from the condition of the repeatability listed in “30. Specifications”.
In order to measure data correctly, do not apply vibration or drafts while collecting data.
With the password function enabled, only logged in user who is allowed to operate the function table
can use this function.

Displays the received data and saves it as a text file (.txt).
Communicates with multiple balances by performing multiple operations.
Runs at the same time as other applications. (Does not occupy the computer)
Receives the GLP compliant output data of the balance.

“RsKey”

Enters the weighing data of the balance directly into other applications.
Any type of application, such as Word or Excel, can be used as long as keyboard input is possible.
Inputs the GLP compliant output of the balance.
The test display function allows you to use your computer as an external display for the balance.

“RsWeight”

The received data can be graphed in real time.
The maximum value, minimum value, average value, standard deviation, fluctuation count, etc. of
the received data can be calculated and displayed.

When the balance receives a command requesting data:
If the balance can output the data, it sends the requested data.
If the balance cannot output the data, it sends an error code (EC,Exx).
When the balance receives a control command,
The balance will send an AK code (acknowledgment, ASCII 06h) upon confirmation of receipt of thecommand and completion of the process.
If the balance cannot execute the command, it sends an error code (EC, Exx).
The following control commands have multiple responses from the balance during processing.
(Refer to the next page.)
An <AK> code (acknowledgement, ASCII 06h) will be sent when the command is confirmed andeach process ends. If the balance cannot execute the command process, it sends an error code

The key switches of the balance can be locked by sending a specified command to the balance. Thisis a useful function when you want to control the balance only with an external device such as apersonal computer.
Even in the key lock state, it is possible to operate the keys with the key control commands. For the
key control commands, refer to “22. Commands”.
Key lock state can be checked by sending a command to check the state to the balance.
Key lock is maintained until either a command is sent to the balance to release or the power isturned off by unplugging the AC adapter.

Locking all key switches
All the key switches of the balance can be disabled by sending a KL command to the balance.

26. Maintenance

Treatment of the balance

When cleaning the balance, wipe it with a lint free cloth that is moistened with a little neutral
detergent.
Do not use organic solvents or chemical cleaning cloths to clean the balance.
Do not disassemble the balance.
When transporting the balance, use the packing material and box that the balance was containedat the time of purchase.
For transportation, remove the following parts from the balance main body:
Weighing pan parts (weighing pan, pan support, dust plate, breeze break ring, breeze breakbottom plate)
Small glass breeze break parts (side panes (3), top pane, base stand)Breeze break front glass, breeze break doors, breeze break top door, attached cables)

12827. Troubleshooting

Checking the balance performance and environment

Since the balance is a precision instrument, in some cases it may not be able to measure correct
values due to adverse effects of the measurement environment or measurement method.
If repeatability is poor when the sample is loaded and unloaded several times, or if the balance
seems to be operating abnormally, check the following items. If the problem persists after checking
each item, contact your local A&D dealer for repair. "Frequently Asked Questions" and answers tothem are also posted on our website ( https://www.aandd.jp ).

1. Checking that the balance works properly.

Method 1. As a simpler test, check the repeatability with an external weight. Be sure to place theweight in the center of the weighing pan.
Method 2. As a precise test, check the repeatability, linearity, weighing value, etc. with a weight of aknown weight.

2. Checking that the measurement environment and method are appropriate.
Check the following check items.

Operating environment

Is the table on which the balance is placed sturdy? (Specifically for BA-6E/BA-6DE)
Is the balance level? For how to adjust the bubble spirit level, refer to “2.4. Precautions during use
for more accurate weighing”.
Is the operating environment free from vibration and drafts?
Is there any strong electrical or magnetic noise source such as a motor near the balance?

Weighing method

Is the weighing pan set so that it does not touch other parts such as the breeze break and dust plateframe? (Is it installed correctly?)
Do you always press the RE-ZERO key before placing your sample on the weighing pan?
Do you place your sample in the center of the weighing pan?
Did you perform a sensitivity adjustment before weighing?
Did you warm up the balance before weighing for at least an hour with the AC adapter connected tothe power supply?

Sample and container

Is the sample free from moisture absorption or evaporation due to the influence of ambient
temperature and humidity?
Is the temperature of the container of the sample acclimatized to the ambient temperature? Refer to“2.4. Precautions during use for more accurate weighing”.
Is the sample free of static electricity? Refer to “2.4. Precautions during use for more accurate
weighing”. The sample may be charged with static electricity especially with the BA-6E/BA-6DE
when the relative humidity is low.
Is the sample a magnetic material (iron, etc.)? Care must be taken when weighing magnetic
materials. Refer to “2.4. Precautions during use for more accurate weighing”.
129

Other display
The automatic sensitivity adjustment notice (theindicator blinking) indicatesthat the automatic sensitivity adjustment will start.
If the balance is not used for a certain period of time with this indicator blinking, thebalance automatically performs sensitivity adjustment using the internal weight.
(The blinking period depends on the operating environment.)
Tips

Although it is possible to continue using the balance even while this mark is
blinking, use after sensitivity adjustment is completed is advisable in order tomaintain the weighing accuracy.

Asking for repair
If the balance needs service or repair, contact your local A&D dealer.
The balance is a precision instrument. Use much care when handling the balance when transporting
the balance.
Use the packing material and box that the balance was contained in at the time of purchase.
Remove the weighing pan and pan support from the main unit of the balance.

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, insulatorssuch as powders, filters, and weighing paper, tend to be charged when the humidity is 45% RH orless, and an error of a few milligrams may occur during weighing. By removing static from theweighing object with the ionizer, it is possible to eliminate the error in the weighing value due tocharging, and correct weighing can be performed.

Usage
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 “2.2. 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 theionizer 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 three 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.

Maintaining the ionizer
Caution: Do not touch electrode units while the ionizer is in operation. Doing so may result in electric
shock.
Dust and other substances adhere to the electrode needle area of the ionizer over time, degrading
the static elimination capacity. To maintain the performance, clean the electrode needle on electrodeunits with a dry cotton swab, etc. on a regular basis.
If the static elimination capacity does not recover because the tip of the electrode needle on anelectrode unit is worn out, replace all of the four electrode units with new ones. The lifetime ofelectrode units is approx. 10000 hours.

Replacement procedure
Step 1. Disconnect the balance connection cable and turn off the power.
Step 2. Rotate electrode units counterclockwise by 45° to pull them out.
Step 3. Insert new electrode units and rotate them clockwise by 45° to secure them.
