Page 9

3. Precautions

To get the optimum performance from the balance and acquire accurate weight data, note the

following:

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.

Red circle Bubble

When the bubble is off to the left :

Turn the leveling foot on the front right in the

clockwise direction.

When the bubble is off to the backward position :

Turn both leveling feet on the front in the

clockwise 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.

)".

When the bubble is off to the right :

Turn the leveling foot on the front left in the

clockwise direction.

When the bubble is off to the forward position:

Turn both leveling feet on the front in the

counterclockwise direction at the same time.

Page 10

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. Ground

the 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.

This 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 underhook on the bottom of the balance to suspend the material away from the influence of the magnet.

Eliminate the temperature difference between a sample and

the environment. When a sample is warmer (cooler) than the ambient temperature, the sample will be lighter (heavier) than the true weight. This error is due to a rising (falling) draft around the sample.

Charged material

Material case

Grounding

Magnetic material

Make each weighing gently and quickly to avoid errors caused by the evaporation of moisture from

the 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 even when 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.

Page 11

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 is

moistened 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 the balance. For accurate weighing, allow the balance to reach equilibrium with room temperature, and then 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 the weighing mode. Depending on the load condition at that time, the balance will automatically judge whether to perform zero or tare operation. The condition for determining which is used is "Power-on zero range", and when 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.

This is the mode to determine the number of objects in a sample based on the standard sample unit

mass. The unit mass means the mass of one piece of the sample. The smaller the variables in each sample unit mass are, the more accurate the counting will be. The balance is equipped with the Automatic 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 storing

mode. 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

Notes

If the balance judges that the mass of the samples is too light and is not adequate to be used

as 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 the weighing 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,

150- appears 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.

Page 20

For a more accurate counting operation, use samples with a unit mass of at least ten or more

times the minimum weighing value of the balance. For example, when a balance with a mimimum 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-volatile

memory.

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

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 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.

Processing indicator

9 The balance re-calculates the unit mass while the processing indicator is blinking. Do not touch the

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 the improved

unit mass.

6-5. Statistical Calculation Mode

The statistical calculation mode statistically calculates the weight data, and displays or outputs the

results. To use the statistical calculation mode, set the "Application function (apf)" parameter of "Application (ap fnc)" in the function table to "2", as described below.

Statistical items available are number of data, sum, maximum, minimum, range (maximum-minimum),

average, standard deviation, coefficient of variation and relative error. What statistical items to output

can be selected from the four modes in the function table. The wrong data input can be canceled by the key operation, if immediately after the input. Turning the balance off will delete the statistical data. The standard deviation, coefficient of variation and relative error are obtained by the equation below:

Standard deviation = where Xi is the i-th weight data, N is number of data.

Coefficient of variation (CV) = x 100 (%)

Relative error of maximum value = x 100 (%)

Relative error of minimum value = x 100 (%)

Note

When data with the minimum weighing value turned off are used in the statistical calculation,

results will be displayed with the minimum weighing value turned off. (The minimum weighing

value will be rounded off.)

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 in

order 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 mass

and 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 printer

or personal computer is required. Calibration test is available only when "GLP output ( info )" of "Data output ( dout )" is set to "1", "2" or

"3".

Caution on Using an External Weight

The accuracy of an external weight will influence the accuracy of weighing. Select an appropriate

weight as listed below:

Cond 0 This 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 .

Cond 2 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 .

Note

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 per

second is less than the parameter, the balance displays the stabilization indicator and outputs the data. The parameter influences the "Auto print mode".

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

5t-b 2 This parameter ignores slight fluctuation of a weight value. Used to prevent a weight value

from drifting due to vibration or drafts.

Note

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

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. When the 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 mode indicator 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)".

When the weight data is only a few digits, turn the function off for accurate weighing.

Note

Digit indicates a unit of minimum weighing value.

trc 0 The tracking function is not used. Used for weighing a very light sample. trc 1 The tracking function is used. Normal zero tracking. trc 2 The tracking function is used. Strong zero tracking. trc 3 The tracking function is used. Very strong zero tracking.

Display Refresh Rate ( 5pd )

Period to refresh the display. This parameter influences "Stream mode" along with "Baud rate" and

"Data output pause".

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 the

balance 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

mode}.)

13. Density Measurement (Specific Gravity)

The balance is equipped with a density mode. It calculates the density of a solid using the mass value

of 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 liquid

density. Where A : Mass value of a sample in air B : Mass value of a sample in liquid

ρ = x ρ

Density of a Liquid

By using a float with a known volume, the density of a liquid can be obtained by the mass value of the

float in air and liquid, using the volume of the float. Where A : Mass value of the float in air B : Mass value of the float in liquid V : Volume of the float

ρ =

Page 79

17-4. 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 each

balance 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 of

variation.

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 to

obtain 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 printer The 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 be

obtained.

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.)

18-2. Acknowledge Code and Error Codes

When the "AK, Error code (erCd)" parameter of "Serial interface ( 5if )" is set to "1", the balance

outputs <AK> code or an error code for each command as follows:

<AK> (06h) Acknowledge in ASCII code.

When the balance receives a command to request data and can not process it, the balance transmits

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 can not process it, the balance

transmits an error code (EC, Exx).

When the balance receives a command to control the balance and can process it, the balance

transmits the acknowledge code.

Among commands to control the balance, the following transmit the acknowledge code both when the

22. Troubleshooting

22-1. Checking the Balance Performance and Environment

The balance is a precision instrument. When the operating environment or the operating method is

inadequate, 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, "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 of

the 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 Container

Has the sample absorbed or lost moisture due to the ambient conditions such as temperature and

humidity?

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".

26-1. Terms

Stable value The weight data when the stabilization indicator appears.

Environment Ambient conditions such as vibration, drafts, temperature, static electricity and

magnetic fields which affect the weighing operation.

Calibration Adjustment of the balance so that it can weigh accurately.

Output To 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 displayed

when 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-zero To 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 and

removed repetitively. Usually expressed as a standard deviation.

e.g. Standard deviation=1 digit: This means that measured values fall within

in 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/

changes by 10

0.0002%/

°C, the value displayed changes by the following value.

°C x 10°C x 200 g = 4 mg

°C : If a load is 200 g and the temperature
