Do not use the AC adapter provided with the balance for other models or equipment withwhich the AC adapter may not be compatible.
If you use the wrong AC adapter, the balance and other equipment may not operate properly.

2-2. Installing the Balance
Install the balance as follows:
1. Place the balance on a solid weighing table. Refer to "3. Precautions" for installing the balance.
2. Assemble the pan support, weighing pan, breeze break ring and breeze break, on the balance asshown in the illustration on page 7.
3. Adjust the leveling feet to level the balance. Confirm it using the bubble spirit level.
4. Confirm that the AC adapter type is correct for the local voltage and power receptacle type.
5. Connect the AC adapter to the balance. Warm up the balance for at least one hour with nothing on theweighing pan.
Note
The AC adapter plug is protected against dust and may be difficult to insert. When inserting
the plug, turn the plug while pushing on it.

Precautions

To get the optimum performance from the balance and acquire accurate weight 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 the first floor
are best, as they are less prone to vibration.
The weighing table should be solid and free from vibration, drafts and as level as possible.
Level the balance by adjusting the leveling feet and confirm it using the bubble spirit level.

counterclockwise direction at the same time.

Ensure a stable power source when using the AC adapter.
Plug in the AC adapter and warm up the balance for at least one hour.
Calibrate the balance before use or after having moved it to another location. Refer to "8. Calibration(Sensitivity Adjustment/Sensitivity Check)".
Caution: Do not install the balance where flammable or corrosive gas is present.

93-2. During Use
Discharge static electricity from the material to be weighed(hereinafter referred to as the sample). When a sample could
have a static charge, the weight data is influenced. Groundthe balance and try the following:
Eliminate static electricity using the optional AD-1683 DC
static eliminator.
Try to keep the ambient humidity above 45%RH.
Use a metal shield case for a charged sample.
Wipe charged plastic samples with a moistened cloth.

Charged material
Material case

GroundingThis balance uses a strong magnet as part of the balance
assembly, so please use caution when weighing magnetic
materials such as iron. If there is a problem, use the underhookon the bottom of the balance to suspend the material awayfrom the influence of the magnet.
Eliminate the temperature difference between a sample andthe environment. When a sample is warmer (cooler) than theambient temperature, the sample will be lighter (heavier) than
the true weight. This error is due to a rising (falling) draft
around the sample.

Magnetic material

Make each weighing gently and quickly to avoid errors caused by the evaporation of moisture fromthe sample or the absorption of moisture by the sample.
Do not drop things upon the weighing pan, or place a sample on the pan that is beyond the balance
weighing capacity. Place a sample in the center of the weighing pan.
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 eliminate possible errors.
Calibrate the balance periodically so as to eliminate possible errors.
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.
The breeze break (The HR-AZ / HR-A series) is provided as a standard accessory. An anti-static
treatment has been applied to the breeze break components, but they may be charged with static
electricity when they are unpacked or when the humidity is low. If the weight value is unstable evenwhen there are no drafts or the balance has a problem with repeatability, remove the breeze break. Or
wipe the clear plates with a moistened cloth, use the optional AD-1683 DC static eliminator or apply an
anti-static spray.

10

3-3. After Use
Avoid mechanical shock to the balance.
Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair.
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.
The edge of the weighing pan is sharp. Use much care when cleaning the pan.
Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid spills
and excessive dust.
The breeze break parts have an antistatic coating. Washing these parts with water, etc., will diminish
the antistatic coating function.

3-4. Power Supply
When the AC adapter is connected, the balance is in the standby mode if the standby indicator is on(refer to "4. Display Symbols and Key Operations"). This is a normal state and does not harm thebalance. For accurate weighing, allow the balance to reach equilibrium with room temperature, andthen warm up the balance for at least one hour before use.

Zero Operation, Tare Operation and Weighing Range
When weighing is started
The balance will determine the reference zero point when the ON: OFF key is pressed to enter theweighing mode.
Depending on the load condition at that time, the balance will automatically judge whether to performzero or tare operation. The condition for determining which is used is "Power-on zero range", andwhen power on zero range is exceeded, the tare operation is performed.
Re-zero operation
By pressing the RE-ZERO key, the display can be set to zero.
The re-zero operation with the RE-ZERO key will automatically judge whether to perform zero or
tare operation. The condition for determining which is used is "Zero range", and when zero range is
exceeded, the tare operation is performed.
Weighing range
The range that the balance can weigh varies depending on the model.
When the total amount (net weight + tare weight) displayed for each model exceeds the maximum
display, E is displayed to indicate that the weighing range is exceeded.
When exceeded in the negative direction, -E is displayed.

6-3. Counting Mode (PCS)This is the mode to determine the number of objects in a sample based on the standard sample unitmass. The unit mass means 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 balance is equipped with theAutomatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Notes
For counting, use samples with a unit mass of at least ten or more times the minimum
weighing value of the balance.
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 Press the MODE key to select(counting mode).

Storing a Sample Unit Mass

2 Press the SAMPLE key to enter the sample unit mass storingmode.
Even in the storing mode, pressing the MODE key will switch
to the next mode.
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 is displayed if 25 is selected in step 3.

Notes
If the balance judges that the mass of the samples is too light and is not adequate to be usedas the unit mass, it displays lo . In that case, store the mass by some quantity.
For example, when the model with the minimum weighing value of 0.0001 g is used and 10
pieces of samples weigh 0.0005 g. Store 100 pieces of samples as 10 and multiply theweighing result by 10.
If the balance judges that the mass of the samples is too light to aquire accurate weighing, it
displays an error requiring the addition of more samples to the specified number. For example,
150appears to require 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.

19

For a more accurate counting operation, use samples with a unit mass of at least ten or moretimes the minimum weighing value of the balance. For example, when a balance with amimimum weighing value of 0.0001 g is used, the recommended sample unit mass is 0.001 g
or more.
The sample unit mass stored, even if the AC adapter is removed, is maintained in non-volatilememory.

Counting Operation

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 (number of objects), using the RS-232C
serial interface.
Note
Peripheral equipment, that is sold separately , such as a
printer or a personal computer is required.

Counting Mode Using the ACAI Function

Processing indicator

The ACAI is a function that improves the accuracy of the unit mass
automatically by increasing the number of samples and averaging
the unit mass variable to minimize the weighing error, as thecounting 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 ofsamples as displayed.
9 The balance re-calculates the unit mass while the processing indicator is blinking. Do not touch thebalance 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 the improved
unit mass.

8. Calibration (Sensitivity Adjustment/Sensitivity Check)

8-1. Calibration Mode

Since the balance's resolution is high, weighing values may change due to gravity and daily
environmental changes. It is necessary to perform calibration (sensitivity adjustment) with the weight inorder to keep the weighing values from changing even if gravity or the environment changes.
Calibrate the balance if it is installed for the first time or relocated, or when the weighing values change
significantly in daily inspection.
Calibration means to adjust the weighing value of the balance using the reference weight or internal
mass. Calibration test means to weigh with the reference weight and compare how much the result
deviates from the reference value. (Calibration test does not perform adjustment.)

Calibration (Sensitivity Adjustment)

Calibration using the internal mass ·············Using the internal mass, adjust the balance with a single
touch. (Only for the HR-AZ series)
Calibration using an external weight ············Using an external weight, adjust the balance.

Calibration Test (Sensitivity Check)

Calibration test using the internal mass ············Checks the accuracy of weighing using the internal massand outputs the result. (Only for the HR-AZ series)* No adjustment is made.
Calibration test using an external weight ··········Checks the accuracy of weighing using an external weight(target weight) and outputs the result.
* No adjustment is made.

Cautions

When calibrating, be sure to install the provided large breeze break.
Do not allow vibration, drafts, or temperature change to affect the balance during calibration.
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 environment has changed.
Do not allow vibration or drafts to affect the balance during calibration.
To output the GLP/GMP compliant report using the RS-232C serial interface, set "GLP output ( info )"of "Data output ( dout )". For details, refer to "10. Function Table". To display the GLP output, a printeror personal computer is required.
Calibration test is available only when "GLP output ( info )" of "Data output ( dout )" is set to "1", "2" or"3".

9. Function Switch and Initialization

9-1. Permit or Inhibit

The balance stores parameters that must not be changed unintentionally. There are two switches forthe purpose of protecting these parameters. You can select either the "permit" or "inhibit" switch. The"inhibit" switch protects parameters against unintentional operations.
Changing the function switch, can be restricted by the password function. When using balance
software version 1.860 or later, the function switch and password function can be used to restrict
calibration (sensitivity adjustment) functions.
The function switch types are as follows:

Description of the Class "Environment, Display"

Condition ( Cond )Cond 0Cond 2This parameter is for sensitive response to the fluctuation of a weight value. Used for powder
target weighing, weighing a very light sample or when quick response weighing is required.
After setting, the balance displays FAST .
This parameter is for stable weighing with slow response. Used to prevent a weight value
from drifting due to vibration or drafts. After setting, the balance displays SLOW .

NoteWith "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 the data.
The parameter influences the "Auto print mode".

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

5t-b 2This parameter ignores slight fluctuation of a weight value. Used to prevent a weight value
from drifting due to vibration or drafts.

NoteWith "Hold function (Hold)" set to "ON (1)", this item is used to set the stabilization range.

44Hold Function ( Hold ) (Animal Weighing Mode)

This function is used to weigh a moving object such as an animal. When the weight data is 0.0200 g or
greater and the display fluctuation is within the stabilization range for a fixed period of averaging time,
the processing indicator illuminates and the balance displays the average weight of the animal. Whenthe animal is removed from the weighing pan, the display returns to zero automatically.
This function is available only when the hold function parameter is set to "1" (the animal modeindicator HOLD illuminates) and any weighing unit other than the counting mode is selected.
The stabilization range and averaging time are set in "Condition (Cond)" and "Stability band width(5t-b)".

Note
This item is selected automatically when the response rate is changed.

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

Auto Display-On ( p-on )When the AC adapter is connected, the display is automatically turned on in the weighing mode,
without the ON:OFF key operation. Used when the balance is built into an automated system. One
hour warm up is necessary for accurate weighing.

Auto Display-Off ( poff )This function automatically turns off the balance display, if the weighing value is 0.5 g or less and thebalance is in the no key operation or no command has been received for approx. 10 minutes.
(The balance has the same power requirement in the weighing state as in the off state {standby

11. ID Number and GLP Report
The ID number is used to identify the balance when Good Laboratory Practice (GLP) or Good
Manufacturing Practice (GMP) is used.
The ID number is maintained in non-volatile memory even if the AC adapter is removed.
The output format for GLP/GMP compliant report is selected at "GLP output (info)" of the function
table and can be output to a personal computer or printer using the RS-232C serial interface.
The GLP/GMP compliant report includes the balance manufacturer, model, serial number, ID number
and space for signature for weight data, and the weight used and results for calibration or calibration
test data.
The HR-AZ series balance is equipped with the built-in clock and can print the date and time using theclock function.
With the HR-A series, when the AD-8121B printer is used, the date and time can be printed using theAD-8121B clock and calendar function. In this case, set the "GLP output ( info )" parameter to "1".
When an AD-8127 printer is connected to the balance and outputs the GLP report, the date and time
can be added to the report using the clock function of the printer. (Available for balance with software
version 1.860 or later)This is very useful for managing the date and time using the AD-8127 password lock function toprevent them from being falsified.
To output the GLP/GMP compliant report, set the AD-8127 printer to the dump printing mode.
The balance can output the following:"Calibration report" of the calibration, using the internal mass (Calibration due to changes intemperature and one-touch calibration.)"Calibration report" of the calibration, using an external weight.
"Calibration test report" of the calibration test, using an external weight and using the internal mass.

GLP Report

To output the GLP/GMP compliant report to an AD-8121B printer, AD-8127 printer or PC, set the "GLP
output ( info )" parameter of the function table to "1" (AD-8121 format), or "2" (General format using
the balance built-in clock data) or "3" (General format using the external device clock data).
Notes on how to output the GLP/GMP compliant report to an AD-8121B/AD-8127 printer
Refer to "17. Connection to Peripheral Equipment" for connection to a printer.
With the AD-8121B printer, use MODE3. If MODE1 is used, select temporarily the dump print modeby pressing the STAT. key of the AD-8121B printer.
With the AD-8127 printer, use the dump printing mode. If the external key printing mode is used, press
and hold the ENT key of the AD-8127 printer to switch between the external key printing mode andthe dump printing mode.
Set "Data output pause (pU5e)" of the function to "1".
If the date and time are not correct when the HR-AZ series balance buit-in clock data is output (info 1,2), set the correct date and time in "Clock (Cl adj)" of the function table. With the HR-A series, set thecorrect date and time of the AD-8121B clock and calendar.
"info 3" is available for balances with software version 1.860 and later.

Outputting the Clock Data of the External Device "info 3" (with Software Version 1.860 or Later)
When the function table is set to "info 3 ", the clock data of external devices such as a printer or PC
can be used instead of the balance built-in clock data for the GLP/GMP compliant report.
This is useful standardizing the clock data using the clock function of an external device.
Except for date and time, the same format as "info 2 " is used.
Notes"info 3 " is available for balances with software version 1.860 and later.
To output the clock data of an external device, the external device such as an AD-8127 printer ordata communication tools software Win CT RsCom must have a function to output the date andtime when <ESC>D or <ESC>T is received.

13. Density Measurement (Specific Gravity)
The balance is equipped with a density mode. It calculates the density of a solid using the mass valueof a sample in air and the mass value in liquid. We recommend the use of the AD-1654 Density
Determination Kit.
Notes
The density mode ( ) was not selected for use when the balance was shipped from the factory.
To use this mode, change the function table settings to activate the density mode.
Refer to "5-2. Storing Units".
The minimum display is 0.0001 g while using the density mode.

Formula to Obtain the Density
Density of a Solid

The density of a solid can be obtained by the mass value of each sample in air, liquid and the liquiddensity.
Whereρ : Density of a sample

Using Windows Communication Tools (WinCT)

When Windows is used as an operating system in a personal computer, the WinCT software, that is
downloaded from the A&D website, can be used to transmit the weight data to the personal computer.
The WinCT has three communication methods: "RsCom", "RsKey" and "RsWeight".

RsCom

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

RsKey

Can transmit the weight data output from the balance directly to other application software such as
Microsoft Excel.
Can be used with most application software.

RsWeight

Can retrieve the weight data from the balance and display the data as a graph in real time.
Can calculate and display the maximum, minimum, average, standard deviation and coefficient ofvariation.

Using the WinCT Software, the Balance Can Do the Following:

1 Analyzing the weight data and the statistics with "RsKey"
The weight data can be input directly into an Excel worksheet. Then, Excel can analyze the data toobtain sum, average, standard deviation, maximum and minimum value, and display them as 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 "send weight 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 a personal computer.
4 Receiving weight data at a certain interval
The weight data can be received at a certain interval and data characteristic with elapsed time can beobtained.
5 Using a personal computer as an external indicator
With the "RsKey" test mode function, a personal computer can be used as an external weight indicator
for the balance. (To do this, set the balance data output mode to stream mode.)7918. Commands

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 can not be performed. Place a sample on the pan and remove it, and repeat
this several times. If the balance seems to have a problem with repeatability or to perform improperly,
check as described below. Also, visit our website, http://www.aadd.jp/, for "Information Library" and"FAQ". If improper performance persists after checking, contact the local A&D dealer for repair.

Checking That the Balance Performs Properly

Check the balance repeatability using an external weight. Be sure to place the weight in the center ofthe weighing pan.
Check the balance repeatability, linearity and calibrated value using external weights with a known value.

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 breeze break been installed?
Is there a strong electrical or magnetic noise source such as a motor near the balance?

Weighing Method

Is the weighing pan installed correctly?
Is the RE-ZERO key pressed before placing a sample on the weighing pan?
Is the sample placed in the center of the weighing pan?
Has the balance been calibrated using an external weight? (Or one-touch calibration, only for the
HR-AZ series)
Has the balance been warmed up for 30 minutes before weighing?

Sample and ContainerHas the sample absorbed or lost moisture due to the ambient conditions such as temperature andhumidity?
Has the temperature of the container been allowed to equalize to the ambient temperature? Refer to"3-2. During Use".
Is the sample charged with static electricity? Refer to "3-2. During Use".
The HR-AZ / HR-A series balances are prone to be charged with static electricity when the relative
humidity is low.
Is the sample of magnetic material such as iron? Caution is required for weighing magnetic materials.
Refer to "3-2. During Use".

Weighing Environment Logger

AD-1688

Data Logger

A 27-kg table with vibration-absorbing rubber feet, to reduce vibration
coming from the floor to enable stable weighing.
Use the AD-8922A remote controller to avoid weighing errors that canbe caused by slight table tilting when operating the scale manually.

Protects the balance from wind from sources such as air conditioning or people
passing by, thereby reducing balance weighing error.
The transparent panel assembly consists of antistatic plastic material that
protects the balance from static electricity.

Used to minimize weighing errors due to static electricity on the material.
The AD-1683 is direct-current static eliminator. The ions generated produce
no breeze and are effective over a long distance. Therefore, the balance
can accurately weight powders, etc. by using the AD-1683.

This option measures the amount of the static charge on the sample, tareor peripheral equipment and displays the result.
If those are found to be charged, discharge them using the AD-1683 DC
static eliminator.

A data logger equipped with 4 sensors for temperature, humidity,
barometric pressure and vibration that can measure and store
environmental data.
When connected to the RS-232C interface of the balance, the AD-1687 canstore environmental data along with weighing data. Therefore, it is possible tostore data in an environment where a computer can not be used.
The stored data can be read to a personal computer using USB.
As the AD-1687 is recognized as USB memory, special software is not
required to read the data.

When connected to the RS-232C interface of the balance, the AD-1688 canstore the data in an environment where a personal computer can not be used.
The stored data can be read to a personal computer using USB. As the
AD-1688 is recognized as USB memory, special software is not required toread the data.

Terms

Stable value

The weight data when the stabilization indicator appears.

Environment

Ambient conditions such as vibration, drafts, temperature, static electricity andmagnetic fields which affect the weighing operation.

Calibration

Adjustment of the balance so that it can weigh accurately.

OutputTo output the weight data using the RS-232C serial interface.

Zero point

A weighing reference point or the zero display. Usually refers to the value displayedwhen nothing is on the weighing pan.

Digit

Unit of digital resolution. Used for the balance, a unit of minimum weighing value.

Tare

To cancel the weight of a container which is not included in the weight data.

Mode

Balance operational function.

Re-zeroTo set the display to zero.

GLP

Good Laboratory Practice.

GMP

Good Manufacturing 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 digitin the frequency of about 68%.

Stabilization time

Time required after a sample being placed, until the stabilization indicator illuminates
and the weight data is displayed.

Sensitivity drift

An affect that a change in temperature causes to the weight data. Expressed as
temperature coefficient.
e.g. Temperature coefficient = 2 ppm/°C : If a load is 200 g and the temperaturechanges by 10°C, the value displayed changes by the following value.
0.0002%/°C x 10°C x 200 g = 4 mg
