8. After the balance has been installed, calibrate the balance using the calibration weight provided
with the balance. For details, refer to “8. CALIBRATION”.
9. A special weighing pan designed appropriately for the sample to be weighed or the peripheral
system can be attached to the balance. About how to design a weighing pan, refer to “24
DESIGNING A SPECIAL WEIGHING PAN”.

11

3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weighing data, note thefollowing:

3-1 Before Use
 Install the balance in an environment where the temperature and humidity are not excessive.
The best operating temperature is about 20°C / 68°F at about 50% relative humidity.
 Install the balance where it is not exposed to direct sunlight and it is not affected by heaters
or air conditioners.
 Install the balance where it is free of dust.
 Install the balance away from equipment which produces magnetic fields.
 Install the balance in a stable place avoiding vibration and shock. Corners of rooms on thefirst floor are best, as they are less prone to vibration.
 The AD-4212A/B series balance responds even to very subtle
airflow. To avoid the influence of ambient airflow or airflow
caused by balance operation, make sure to use the dust
guard and the breeze ring (AD-4212B-101/102 only).
 Level the weighing unit by adjusting the leveling feetand confirm it using the bubble spirit level.
 If the leveling adjustment is difficult to perform due tothe installation conditions, perform calibration using acalibration weight or controlled actual sample before
weighing.
 Ensure a stable power source when using the AC
adapter Warm up the balance for the appropriate duration. Plugin the AC adapter as usual.
• AD-4212A series balance: 30 minutes or more
• AD-4212B series balance: one hour or more
 Calibrate the balance before use or after having moved
it to another location.
In addition, calibrate it periodically to maintain the accuracy.

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

123-2 When Building into a System
The AD-4212A/B is a precision balance. When it is built into a system and used, errors such as
unstable weight values may occur due to static electricity, vibration and materials used for thedevices near the balance.
When using the balance that is built into a system, take the following precautions.
 Errors due to a static charge
When the ambient humidity is less than 45% RH, insulators such as plastic or glass are prone to static
electricity. When charged material comes close to the balance, a pulling force is generated between
the charged material and the weighing pan. This causes an unstable weight value.
To protect the balance against a discharge generated by charged material when it comes close
to the balance, make sure to earth ground the weighing unit and the display unit.
(Static electricity generated by static induction will not be canceled by earth-grounding.)
Charged plastic breeze break
The pulling force
makes the weightvalue unstable

A pulling force generated between
the charged sample and the balancecauses an unstable weight value.

Measures to take (Plastic is used in the measures below. They can be applied to glass, too.)
When the sample or devices are plastic
 Use a static eliminator that generates no air blow such as the
AD-1683, DC static eliminator, to remove static electricity.
 Place the sample in a container that is made of a conductive
material such as metal and that can be sealed and weigh it.
When the sample is powdery When the balance is used in combination with a feeder forbatch weighing of powdery samples, samples may becharged by rubbing sample particles against each other.
Use a static eliminator and perform weighing while removing
static electricity.

Chargedmaterial
Metal case

Grounding

When the sample container is made of material that is prone to static electricity such as plastic
 Cover the outside of the container with a metal such as aluminum foil.
 Apply an anti-static agent onto the container.
When making a breeze break using plastic
 Apply an anti-static agent onto the breeze break.
 Use a conductive acrylic fiber.
When plastic exists in the balance installation site Cover the plastic with a grounded metal.
 Apply an anti-static agent onto plastic.

13

When an operator is static charged
If an operator’s clothes are static charged, especially in winter, it may be a cause forunstable weight values.
 Wear an anti-static wrist strap.


Errors due to airflow
Where the influence of ambient airflow is greatsuch as: close to an air conditioner, door or
passage way. Even very subtle airflow that is
hard to be detected may influence the weighing
operation.
 Avoid those areas as a weighing site.
 If weighing is to be performed in such anarea, use a breeze break or take otherappropriate measures.

Influence of the air flow
makes the weightvalue unstable

Where the influence of heat or drafts is great Eliminate temperature differences between
a sample and the environment.
When a sample is warmer (cooler) than the
Draft
ambient temperature, the sample will be
40 C
20 C
lighter (heavier) than the true weight. Thiserror is due to a rising (falling) draft aroundthe sample.
 Do not touch the sample directly with yourhand. Use tweezers or other tools.
If you touch the sample, the same typeerror described above will occur.
 Do not perform weighing where it is exposed to direct sunlight. Weighing errors may
occur due to sudden temperature change or drafts.
Where the influence of vibration is great, such as:(1) Soft ground (2) Second or higher floor (3) Near center of a floor far from pillars (4) Seismic
isolated structures (5) Near tall buildings.
In the areas listed above, the scale may yield unstable weight values on windy days or after anearthquake. Especially in case of (4) and (5), weight values may be unstable during and for along period of time after strong winds or an earthquake.
 Error due to moving the weighing unit
The performance of this device is guaranteed on the condition that it does not move.
When incorporating the weighing unit into a system where the main body moves, pay
sufficient attention to the following and perform sufficient preliminary checks.
If you move the weighing unit, it may be damaged due to impact.
Also, the weight value will not be stable immediately after moving.
Avoid sudden movement, stopping, and impact, and allow sufficient waiting time for the weightvalue to stabilize when acquiring the weighing data.
The device used to move the balance should have a structure that can maintain thehorizontality of the weighing unit. If the levelness shifts, zero point and sensitivity shift will
occur, so perform re-zero operation and calibration in that case.
In order to avoid the influence of vibration, the platform used for moving should be made tohave a structure that is not very susceptible to vibration, such as reducing play on moving
parts.
14 Errors due to other causes
Change in temperature or humidity
A sudden change in temperature or humidity can generate a draft and cause the balance toabsorb or exude moisture, which leads to weighing errors.
 Avoid sudden change in temperature or humidity.
 Use an air conditioner to control the temperature or humidity.
Magnetic material
The balance uses a strong magnet as part of the balance assembly, so use much care whenweighing magnetic materials.
 Place a non-magnetic object such as aluminum or brass between the sample and thebalance, also keep an appropriate distance between them while weighing.

3-3 During Use
 To minimize the affect by electrical noises, earth groundthe weighing unit and the display unit.
 Make each weighing gently and quickly to avoid errors
due to changes in the environmental conditions.
 Do not drop things upon the weighing pan, or place asample on the pan that is beyond the balance weighing
capacity. Place a sample in the center of the weighingpan.
 Do not use a sharp instrument such as a pencil to press
the keys. Use your finger only.
 Press the RE-ZERO key before each weighing to prevent
possible errors. In addition, a RE-ZERO signal can besent using external contact input/RS-232C command.
 Take into consideration the affect of air buoyancy on a sample when more accuracy is required.
 Keep the balance interior free of dust and foreign materials.

3-4 After Use Avoid mechanical shock to the balance.
 Calibrate the balance, using a calibration weight, periodically.
 Do not disassemble the balance. Contact the local A&D dealer if the balance needs service orrepair.
 Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that ismoistened with warm water and a mild detergent.
 Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid
spills and excessive dust.

3-5 Power Supply When the AC adapter is connected, the balance is in the standby mode if the standby indicator ison (refer to “4 DISPLAY SYMBOLS AND KEY OPERATION”). This is a normal state and does
not harm the balance. For accurate weighing, plug in the AC adapter and warm up the balance
for the appropriate duration before use.

8. CALIBRATION
Calibration
Calibration using the calibration weight
Calibration is possible without removing the special weighing pan or jig attached to the weighingpan.
(However, as long as the total of the special plate and jig and the calibration weight used does notexceed the capacity of the balance.)

Calibration test
To check the weighing accuracy using the calibration weight and output the result.
(Calibration test does not perform calibration.)

Caution Calibration adjusts the balance for accurate weighing.
Besides periodic calibration and before each use, perform calibration when:• the balance is installed for the first time.
• the balance has been moved.
• the ambient conditions have changed.
 Do not allow vibration or drafts to affect the balance during calibration.
 To output the data for GLP using the RS-232C interface, set “GLP output ( info )” of “Dataoutput ( dout )”. For details, refer to “10. FUNCTION TABLE”. Time and date are added to the
GLP report. If the time or date is not correct, adjust them. For details, refer to “10-9 Clock andCalendar Function”.
 Calibration test is available only when “GLP output ( info )” of “Data output ( dout )” is set to “1” or “2”.
 The calibration and calibration test data can be stored in memory. To store them, set “Datamemory ( data )” to “3”. For details, refer to “14. DATA MEMORY”.

Caution on using an external calibration weight The accuracy of the weight can influence the accuracy of weighing. Select an appropriate
weight as listed below. A calibration weight (conforming to OIML, Class E2 or equivalent) is
provided with the balance as a standard accessory.

Available only for the AD-4212A series balance when “To use
the extended functions” is selected for the function switch and isused for special applications.
For details, refer to “20. EXTENDED FUNCTIONS”.

Factory setting*4“Not weighing” is a condition that a weight value is not displayed such as re-zero operation or
display-off state.

CautionThe balance may not transmit the data completely at the specified refresh rate, depending on
the baud rate or data added to the weighing data such as time, date or ID number.

10-4 Description of the Class “Environment, Display”
Condition ( Cond )Cond 0Cond 2This parameter is for sensitive response to the fluctuation of a weight value.
Used when fast weighing speed is required.
After setting, the balance displays FAST.
This parameter is for stable weighing with slow response. Used to prevent aweight value drift due to vibration or drafts.
After setting, the balance displays SLOW.
Note
For the AD-4212A series balance, with “Hold function (Hold)” set to “ON(1)”, this item is used to set the averaging time.

Stability band width ( 5t-b )This item controls the width to regard a weight value as a stable value. When the fluctuation persecond is less than the parameter, the balance displays the stabilization indicator and outputs orstores the data. The parameter influences the “Auto print mode”

5t-b 0This parameter is for sensitive response of the stabilization indicator. Usedfor exact weighing.

5t-b 2This parameter ignores slight fluctuations of a weight value. Used to preventa weight value from drifting due to vibration or drafts.
Note
For the AD-4212A series balance, with “Hold function (Hold)” set to“ON (1)”, this item is used to set the stabilization range..

Hold function ( Hold ) (Animal weighing mode, AD-4212A only)This function is used to weigh a moving object such as an animal.
When the weight value is over the weighing range from zero and the display fluctuation is within thestabilization range for a fixed period of averaging time, the processing indicator illuminates and thebalance displays the average weight of the animal. When the animal is removed from the weighingpan, the display returns to zero automatically.
This function is available only when the hold function parameter is set to “1” (the animal modeindicator ANIMAL illuminates) and any weighing unit other than the counting mode is selected.
The averaging time and stabilization range are set in “Condition (Cond)” and “Stability band width (5t-b)”.

Zero tracking ( trc )This function tracks zero point drift caused by changes in the environment and stabilizes the zero
point. Three levels of zero tracking are available. When the weight value is only a few digits, turn thefunction off for accurate weighing.
Note
Digit, when used for the AD-4212A/B series balance, indicates the minimum displayable weighing value.

The tracking function is used. Strong zero tracking.
The tracking function is used. Very strong zero tracking

Display refresh rate ( 5pd )Frequency to refresh the display. This parameter influences “BCD output”, "Comparator contact
output" and “Stream mode”.
Note
The balance may not transmit the data completely at the specified refresh rate, depending on
the baud rate or data added to the weighing data such as time, date or ID number.

Decimal point ( pnt )The decimal point format can be selected.

Auto display-ON ( p-on )When the AC adapter is plugged in, the display is automatically turned on without the ON:OFF key
operation, to display the weighing mode. Used when the balance is built into an automated system.
A warm up for the appropriate duration is necessary for accurate weighing.

Auto display-OFF ( poff ) (AD-4212A only)
When the AC adapter is connected and no operation is performed (inactivity state) for 10 minutes, thedisplay is automatically turned off and the standby indicator is illuminated.

Capacity indicator ( g5i )In the weighing mode, the indicator displays the weighing data relative to the weighing capacity inpercentage. (Zero = 0%, maximum capacity = 100%)
When the “Data memory ( data )” parameter is set to parameters other than “0” (not used), the indicator
displays the information stored in memory, such as the amount of memory data or data number.

Readability display at start ( rng )When weighing is started, the digit of the readability can be turned off without any key operation. (rng 1)
Weighing can be started with the readability of the previous measurement displayed. (rng 2)

36

Tare at start ( p-tr )When a hopper is attached to the weighing pan and loss-in weighing is performed, the remaining
amount of the material will become unknown if tare is performed each time a weighing starts.
When "p-tr 0" is selected, tare is not performed at weighing start. So, the remaining amount of thematerial can be monitored when the power is turned on. When setting to p-tr 0, do not perform the
RE-ZERO operation frequently.

10-5 Description of the Item “Data output mode”
The parameter setting of the “Data output mode ( prt )” applies to the performance when the “Datamemory ( data )” parameter is set to “2” (to store the weighing data) and when the data is transmittedusing the RS-232C interface.
Notes
Data output to the RS-232C is not available when the BCD output (OP-01) is installed.
BCD output is refreshed at the display refresh rate.

12. COUNTING MODE (PC)This is the mode to determine the number of objects in a sample based on the standard sample unitmass. The unit mass is the mass of one piece of the sample. The smaller the variables in eachsample unit mass are, the more accurate the counting will be. The AD-4212A/B series balance isequipped with the Automatic Counting Accuracy Improvement (ACAI) function to improve the counting
accuracy.
Notes
Use samples with a unit mass of 1 mg or more (AD-4212A-100, AD-4212B series) or 10 mg ormore (AD-4212A-200/600/1000) for counting.
If the sample unit mass variable is too large, it may cause a counting error.
To improve the counting performance, use the ACAI function frequently or divide the samples
into several groups and count each group.

Selecting the counting mode
1 Set “Unit selection ( Unit )” parameter of the function table to pC (counting mode). For
details, refer to “5-2 Changing the Unit”.

Storing a sample unit mass
2 Press the SAMPLE key to enter the sample unit massstoring mode.
To return to the counting mode without storing the sample
unit mass, press the CAL key.
3 To select the number of samples, press the SAMPLE key
several times. It may be set to 10, 25, 50 or 100.
Note
A greater number of samples will yield more accurate counting result.
4 Place a container on the weighing pan, if necessary. Press
the RE-ZERO key to cancel the weight (tare). The number
specified in step 3 appears.
e.g.:
25 0 pC is displayed if 25 is selected in step 3.

5 Place the number of samples specified on the pan. In thisexample, 25 pieces.
6 Wait for the stabilization indicator to be displayed. Pressthe PRINT key to calculate and store the unit mass. Thebalance displays 25 pC (counting mode) and is set tocount samples with this unit mass. (The sample unit massstored, even if the AC adapter is removed, is maintained in
non-volatile memory.)
To improve the accuracy of the unit mass, proceed to step 8.

52

Weighing
panContainer

Sample(25 pieces)

NotesIf the balance judges that the mass of the samples is toolight and is not adequate to be used as the unit mass, it
displays 1lo . In that case, store the mass by some quantity.
For example, when the model with the readability of 0.01 g isused and 10 pieces of samples weigh 0.05 g. Store 100
pieces of samples as 10 and multiply the weighing result by
10.
If the balance judges that the mass of the samples is toolight to aquire accurate weighing, it displays an error
requiring the addition of more samples to the specified
number. In the example above, 150- pC appears, requiring
25 more samples. Add 25 samples and press the PRINT key.
When the unit mass is stored correctly, the balance
proceeds to the counting mode.

7 Place the samples to be counted on the pan.
While the stabilization indicator is on, pressing the PRINT
key will output the weight value, using the RS-232C serialinterface.
Note
Peripheral equipment, that is sold separately, such asa printer or a personal computer is required.

The counting result

Counting mode using the ACAI function
The ACAI is a function that improves the accuracy of the unit
mass automatically by increasing the number of samples andaveraging the unit mass variable to minimize the weighing
error, as the counting process proceeds.
8 If a few more samples are added, the processing indicator turns on. To prevent an error, add
three or more. The processing indicator does not turn on if overloaded. Try to add the same
number of samples as displayed.
9 The balance re-calculates the unit mass while the processing indicator is blinking. Do not touchthe balance or samples on the pan until the processing indicator turns off.
10 Counting accuracy is improved when the processing indicator turns off.
Each time the above operation is performed, a more accurate unit mass will be obtained.
There is no definite upper limit of ACAI range for the number of samples exceeding 100. Try to
add the same number of samples as displayed.
11

Remove all the samples used in ACAI and proceed with the counting operation using theimproved unit mass.

14. DATA MEMORY
Data memory is a function to store weighing data or calibration data to display or output later. The
data memory function can also store multiple upper/lower limit values or unit mass values, for laterselection as necessary.
One of the following data sets can be stored: Weighing data (Up to 200 sets. 100 sets when the time and date are added.) Calibration and calibration test data (latest 50 sets)
 Unit mass in the counting mode (Up to 20 sets)
 Upper/lower limit values (Up to 20 sets)
Note
Data memory function is not available when the BCD output (OP-01) is installed.

14-1 Notes on Using Data Memory
To use the memory function, set the “Data memory ( data )” parameter of the function table. In
addition, for weighing data, set the “Time/Date output (5-td)” parameter. For details on setting thedata memory, refer to “10. FUNCTION TABLE”.
For weighing data, the data contents to be stored and the storage capacity depend on the “Time/Date
output (5-td)” parameter setting.

Releasing “Clr”
If a different type of data exists in memory when the data is stored, “Clr” appears blinking in theupper left of the display. For example, you want to store weighing data but calibration data or unit
mass data remains in memory.

Under such a condition, before storing data, delete the data in memory as follows:
1 Press and hold the PRINT key until SClr no with “no” blinking is displayed, then release the key.
2 Press the RE-ZERO key to display SClr gowith “go” blinking.

The AD-4212A/B series balance is of the DCE type (Data Communication Equipment), which canbe connected to a personal computer using the RS-232C interface.
Before connection, read the personal computer manual thoroughly.
Use a standard DCE cable for connection (cable type: straight through).

17-4 Using Windows Communication Tools (WinCT)
When Windows is used as an operating system in a personal computer, the WinCT software can beused to transmit the weighing data to the personal computer.
The current version of the WinCT can be downloaded from the A&D website. Check for applicable
Windows versions when downloading the software.
For details on WinCT, refer to the WinCT instruction manual which is available on the A&D website.
The WinCT software has two communication methods: “RsCom” and “RsKey”.

RsCom Can transmit commands to control the balance.
 Can make bi-directional communication between the balance and a personal computer using
the RS-232C interface.
 Can display or store the data using a text file format. Can also print the data using a printerconnected to the personal computer.
 When several ports of a personal computer have balances connected, can communicate witheach balance simultaneously.
 Can share a personal computer with other application software.
 Can receive the balance GLP report.

RsKey Can transmit the weighing data output from the balance directly to other application software
such as Microsoft Excel.
 Can be used with most application software.
 Can receive the balance GLP report.

RsWeight
 Balance data can be imported to a PC and graphed in real time.
 The maximum value, minimum value, average value, standard deviation, MAX, MIN, etc. of thedata can be aggregated and graphed, which is convenient for material analysis and quality
control.
Note
Windows and Excel are registered trademarks of Microsoft Corporation.

69

Using the WinCT software, the balance can do the following:
1 Analyzing the weighing data and the statistics with “RsKey”
The weighing data can be input directly into an Excel worksheet. Then, Excel can analyze thedata to obtain total, average, standard deviation, maximum and minimum value, and display
them in a graph.
2 Controlling the balance using commands from a personal computer
By using “RsCom”, the personal computer sends commands such as “re-zero” or “sendweighing data” to the balance and controls the balance.
3 Printing the balance GLP report using your printerThe balance GLP report can be printed using a printer connected to the personal computer.
4 Receiving weighing data at a certain interval
The weighing data can be received at a certain interval and data characteristic with elapsed
time can be obtained.
5 Using the AD-4212A/B series balance memory function
The data can be stored in the balance’s memory. Of the data stored, the weighing data andcalibration data can be transmitted to a personal computer at one time.
6 Using a personal computer as an external indicator
With the “RsKey” test mode function, a personal computer can be used as an external weightindicator for the balance. (To do this, set the balance data output mode to stream mode.)7018. COMMANDS

Notes: nnn indicates a three-digit numerical value.
The command is sent to the balance with the terminator selected in the “Terminator(Crlf)” parameter of “Serial interface ( 5if )” added.

7118-2 Acknowledge Code and Error Codes
When the “Serial interface function ( 5if )” parameter is set to “erCd 1”, the balance outputs <AK>code or error code to each command as follows:<AK> (06h)Acknowledge in ASCII code.

 When the balance receives a command to request data and cannot process it, the balancetransmits an error code (EC, Exx).
When the balance receives a command to request data and can process it, the balance outputs
the data.
 When the balance receives a command to control the balance and cannot process it, thebalance transmits an error code (EC, Exx).
When the balance receives a command to control the balance and can process it, the balancetransmits the acknowledge code.
Among commands to control the balance, the following transmit the acknowledge code bothwhen the balance receives the command and when the balance has accomplished thecommand. If the command cannot be processed properly, the balance transmits an error code
(EC, Exx). This error can be released using the CAL command.
CAL command (Calibration command) ON command (Display ON command)
P command (Display ON/OFF command) R command (RE-ZERO command)
R command example

 When a communication error has occurred due to external noise, or a parity error has occurred
due to transmission error, the balance transmits an error code. In this case, send the commandagain.

72

18-3 Control Using CTS and RTS
Depending on the “Ct5” parameter of “Serial interface ( 5if )”, the balance performs as follows:

Ct5 0
Regardless of whether the balance can receive a command or not, the balance keeps the CTS line HI.
The balance outputs data regardless of the condition of the RTS line.

Ct5 1
The CTS line is kept Hi normally. When the balance cannot receive the next command (e.g. while thebalance is processing last command), the balance sets the CTS line to Lo. The balance confirms thelevel of the RTS line before outputting a set of data. If the RTS level is Hi, the balance outputs data. If
the RTS level is Lo, data is not output (The data is canceled).

18-4 Settings Related to RS-232C
Concerning the RS-232C, the balance has two functions: “Data output ( dout )” and “Serial interface( 5if )”. Set each function as necessary.

7319. BCD OUTPUT (OP-01)
Weighing data will be output in BCD, in sync with the display refreshing. In addition, the polarity (+/-)
and balance condition (stable/not stable, overload(positive/negative)) will be output.
The strobe signal allows inputting data easily. Inputting BUSY will hold data or prevent data that isbeing output from being rewritten. The logic of weighing data, status, and strobe signal can beswitched individually in the function table.
Contact input is available for RE-ZERO and ON/OFF. (The same operations as pressing the
RE-ZERO and ON/OFF keys.)19-1 Connector Pin Nos. and Specifications

The AD-4212A series balance has several extended functions equipped for special applications or totroubleshoot when using the standard functions.
Some settings of the extended functions may affect the weighing accuracy. Therefore, they are set todisabled at the factory when shipped. To enable the extended functions, set the function switch"Extended functions" to "1" (To use the extended functions). For details, refer to "9-1 Permit orInhibit".
When "To use the extended functions” is selected, one item has its setting range extended as shown
below and some more items are added as shown on the next page.

77

78

20-1 Description of "Averaging range" and "Averaging time"
Averaging range ( f1-b ) and averaging time ( f1-t )1. When the fluctuation of a weight value is beyond the range that is selected in "f1-b", theaveraging operation is disabled and the display reflects the varying value.
2. Once the fluctuation becomes within the selected range, the averaging operation starts tostabilize the weight value.
3. The process of averaging increases. When the selected time is reached, moving averaging will
be performed.

When a small amount of sample is weighed or is filled, the fluctuation of a weight value is too small
to be beyond the selected range and the averaging operation is not disabled. Consequently
moving averaging is always performed and it takes a longer time to reach the final weight value.
Under such a situation, change the setting of "f1-b" to a smaller range. But please note that thesmaller the range is, the more prone to external disturbance the value will become.

79

21. MAINTENANCE
 Do not disassemble the balance. Contact the local A&D dealer if the balance needs service orrepair.
 Use the original packing material for transportation.
 Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that ismoistened with warm water and a mild detergent.

22. TROUBLESHOOTING
22-1 Checking the Balance Performance and Environment
The balance is a precision instrument. When the operating environment or the operating method isinadequate, correct weighing cannot be performed. Place a sample on the pan and remove it, andrepeat this several times. If the balance seems to have a problem with repeatability or to perform
improperly, check as described below. If improper performance persists after checking, contact the
local A&D dealer for repair.

Checking that the balance performs properly (AD-4212A only) Check the balance performance using the self-check function.

Operation
1 Press and hold the MODE key until RESPONSE isdisplayed, and then release the key.
2 The balance automatically starts to check its
internal performance
3 After self-check, the balance displays the results
and returns to the weighing mode.
e.g. “ OK”The example above indicates that the result of theself check is good.
Note
If improper performance is found in the self check,the balance displays CH no. Contact the local
A&D dealer for repair.
 Check the balance repeatability using the calibration weight. Be sure to place the weight in thecenter of the weighing pan. Pay attention to the airflow and be sure to use the breeze break.
 Check the balance repeatability, linearity and calibrated value using external weights with aknown value.

80 When the balance is built into a system, remove the balance from the system. Place it on asolid table. Install the breeze break and perform checking.
When the balance proper performance is confirmed, refer to page 12 to set up the installation
site.

Checking that the operating environment or weighing method is proper
Operating environment
 Is the weighing table solid enough Is the balance level? Refer to “3-1 Before Use”.
 Is the operating environment free from vibration and drafts? Has the stainless steel breeze
break been installed?
 Is there a strong electrical or magnetic noise source such as a motor near the balance?
 Is there a heat source near the balance?
Weighing method Does the weighing pan touch the breeze break or anything? Is the weighing pan installed
correctly?
 Is the RE-ZERO key pressed before placing a sample on the weighing pan? Or, is RE-ZERO
performed using external contact input or an RS-232C command?
 Is the sample placed in the center of the weighing pan?
 Has the balance been warmed up for the appropriate duration before weighing?
AD-4212A series balance: 30 minutes or more
AD-4212B series balance: one hour or more Are the leveling feet of the weighing unit placed flat to the installation surface?
If not, the weight value will be unstable or the specified repeatability cannot be obtained.
Improve the installation condition, by securing the weighing unit or reducing the vibration that isconveyed to the weighing unit.
Sample and container
 Has the sample absorbed or lost moisture due to the ambient conditions such as temperatureor humidity?
 Has the temperature of the container been allowed to equalize to the ambient temperature?
Refer to “3-2 When Building into a System”.
 Is the sample charged with static electricity? Refer to “3-2 When Building into a System”.
 Is the sample of magnetic material such as iron? Use much care when weighing magnetic
materials. Refer to “3-2 When Building into a System”.

To save the weighing data, unit mass, calibration data or upper/lower limit values
using the data memory function.
Calibration
Adjustment of the balance so that it can weigh accurately.
OutputTo output the weighing data using the RS-232C interface.
Zero point
A weighing reference point or the zero display. Usually refers to the value
displayed when nothing is on the weighing pan.
Data number
Numbers assigned sequentially when weighing data or unit weight is stored.
Digit
Unit of digital resolution. Used for the balance, the minimum displayable weighing value
Tare
To cancel the weight of a container which is not included in the weighing data.
Mode
Balance operational function.
Re-zeroTo set the display to zero.
GLP
Good Laboratory Practice.
Repeatability
Variation in measured values obtained when the same weight is placed andremoved repetitively. Usually expressed as a standard deviation.
e.g. Standard deviation=1 digit: This means that measured values fall within ±1
digit in the frequency of about 68%.
Stabilization time Time required after a sample being placed, until the stabilization indicatorilluminates and the weighing data is displayed.
Sensitivity drift An affect that a change in temperature causes to the weighing data. Expressed as
temperature coefficient.
e.g. Temperature coefficient = 2 ppm/°C : If a load is 100 g and the temperaturechanges by 10°C, the value displayed changes by the following value.
0.0002%/°C x 10°C x 100 g = 2 mg
