Pennyweight, Grain (UK), Tael (preset in the factory), Tola (India), Messghal, Density mode

BM-22 is equipped with a smart range function to weigh with the precision range (a higher resolution) when zeroing a tare weight within the weighing capacity.

The micro tube holder is included in the accessories of BM-20 and BM-22.

Density mode for calculating the density of a solid.

BM series balances are equipped with an RS-232C serial interface and a USB interface to communicate with a computer. When printing data using the RS-232C interface, by using the USB interface, the data can be transmitted to a computer at the same time. Communications between the BM series balance using the RS-232C interface and a Windows computer using the Windows communication tools software (WinCT) make building a system very easy.

The current version of the Win CT can be downloaded from the A&D website.

Connecting the USB interface of the balance, by cable to a Windows computer, allows transmission of the weighing data to Excel or Word.

When multiple balances have the BM-08 Ethernet interface installed in place of the USB interface and connected to a LAN, data can be acquired from each of them using the WinCT-Plus software.

The weighing data can be stored by connecting the accessory data logger (AD-1688) directly, when not using a computer.

Precautions Before Use

(Environmental Condition And Preparations)

To ensure that you get the most from your balance, please try to follow these conditions as closely as possible. Consider these conditions for BM-20 and BM-22 that are sensitive instrument specially.

The best operating temperature is about 20°C / 68°F at about 50% Relative Humidity.

The weighing room should be free of dust.

Clean the weighing chamber and its surroundings to prevent foreign matter from invading when weighing a very small amount.

The weighing table should be solid and free from vibration, drafts (such as frequently opening doors or windows) and as level as possible. We recommend to use the anti-vibration table

( AD-1671) and remote controller (AD-8922A) for BM-20 and BM-22.

Do not install the balance where it will be subject to vibration. Corners of rooms are best.

Do not install the balance near a heater, air conditioner, or in a breeze. The influence of breezes can be reduced with the tabletop breeze break ( AD-1672).

Do not install the balance in direct sunlight and excessive temperature changes.

Do not use the balance near other equipment which produces magnetic fields.

Adjust the level of the balance using the leveling feet.

Please warm-up the balance for at least one hour. Plug-in the AC adapter as usual.

Calibrate the balance before using and after moving it to another location.

Ensure a stable power source when using the AC adapter.

Do not place or use the balance where there is flammable or corrosive gas present.

Cautions During Use

(For Precision Weighing)

Note the following items to get accurate weighing data.

Discharge static electricity from the weighing material. When weighing sample (plastics, insulator, etc.) could have a static charge, the weight value is influenced. Ground the balance, and

Eliminate the static electricity using the built-in static eliminator.

Try to keep the ambient humidity at or above 45%RH in the room.

Use a metal shield case.

Wipe a charged material (plastic sample etc.) with a damp cloth.

Charged material

Metal case

Grounding

This balance uses a strong magnet as part of the balance assembly, so please use caution when weighing magnetic materials. If there is a problem, use the underhook (refer to "13.Underhook") to suspend the material away from the influence of the magnet.

Eliminate temperature differences between the weighed sample and the environment. When a sample is warmer (cooler) than the ambient temperature, the sample will appear lighter (heavier) than the true mass. This error is due to the rising (falling) draft next the sample. If you touch the sample, the same type error will occur. Do not touch the sample directly with your hand. Use tweezers or other tools.

Do not drop things upon the weighing pan, or place a weight beyond the range of the balance on the weighing pan.

Magnet material

Draft

20°C

Shock

Weighing pan

Make each weighing gently and quickly to avoid errors due to changes in the environmental conditions.

We recommend that the fine range ring and separation plate are used to avoid weighing error caused by drafts when BM-252 displays a weighing value in unit of 0.01 mg (minimum display: 0.01 mg).

Fine range ring

BM-252

We recommend that the small fine range ring, fine range ring and

separation plate are used to avoid weighing error caused by drafts when BM-22 and BM-20 display a weighing value in unit of 0.01 mg and 0.001 mg (minimum display: 0.01 mg and 0.001 mg). To reduce the influence of breezes, minimize operation of doors of the weighing


Fine range ring chamber. In addition, in order to weigh more accurately with reducing the effects of the surrounding environment, it is recommended to use to attach the slide breeze break to weighing room.

BM-20

BM-22

Slide breeze break

The weighing value of BM-22 and BM-20 may change after the stable indicator is displayed. We recommend that you set a

BM-20

BM-22 constant wait time (approx. 10 sec.) between displaying the stable indicator and reading the value.

If the contamination may be a problem, do not use the weighing chamber for the sampling operations to prevent the scattering of matter.

Take into consideration the affect of air buoyancy on a sample when more accuracy is required.

BM series 15

Do not use a sharp instrument (such as a pencil or ball point pen) to press the keys, use your finger only.

Press the RE-ZERO key before each weighing to prevent possible errors.

Avoid foreign matter (dust, liquid or metal fragments) that could get inside the balance.

Operate your balance gently. Shorten the operation time as much as possible (Opening and closing door, putting and removing sample). Use a pair of tweezers to avoid temperature changes due to heat from inserting your hand into the weighing chamber.

3.4.

Cautions After Use

(Management Of The Balance)

Avoid mechanical shock to your balance.

Do not disassemble the balance. Contact your local A&D dealer if your balance needs service or repair.

Do not use solvents to clean the balance. For best cleaning, wipe with a dry lint free cloth or a lint free cloth that is moistened with warm water and a mild detergent.

Avoid foreign matter (dust, liquid or metal fragments) that could get inside the balance.

3.5.

Cautions For Power Supply

Do not remove the AC adapter while the internal mass is in motion, for example, right after the

AC adapter is connected, or during calibration using the internal mass.

If the AC adapter is removed under the conditions described above, the internal mass will be left unsecured, that may cause mechanical damage when the balance is moved.

Before removing the AC adapter, confirm that zero is displayed in the weighing mode, then press the ON:OFF key.

When the AC adapter is connected, the balance is in the standby mode if the standby indicator is on. This is a normal state and does not harm the balance. For accurate weighing, we recommend that you always plug in your balance so it can warm up.

Connect the AC adapter for BM-22 and BM-20 normally.

Built-in DC Static Eliminator

(Neutralization Device)

The BM series is equipped with four DC static eliminator electrode units to neutralize static electricity from a charged weighing sample.

When neutralizing static electricity before weighing, stability can be improved, reducing error.

Neutralizing ion : The discharge electrodes of the built-in DC static eliminator continuously generate bipolar ions by corona discharge. Applying these ions to the weighing sample neutralizes the static charge.

Static electricity : In general, when the ambient humidity is less than 45%RH, powders, paper, plastic, nonconductors, etc., easily become charged with static electricity. The influence of the static electricity may cause a weighing error of several milligrams. The static eliminator effectively neutralizes the electrical charge.

Operation

Repeatability Test

The repeatability means the weighing error when measuring the same mass repeatedly.

The standard deviation is generally used for the indicator of the repeatability.

The repeatability test measures the built -in mass 10 times and displays the standard deviation.

Use the repeatability test to inspect the performance of the balance when changing environment or when moving the balance to a new location.

Example: "The standard deviation = 0.2 mg" means that the probability of weighing error within

±0.2 mg is approx. 68% when measuring the same mass repeatedly.

Note

The repeatability test uses the internal mass. Therefore, the standard deviation discords to item repeatability of " 18.Specifications". Regard the standard deviation as a reference.

Automatic Self Calibration

(For variation of ambient temperature)

Automatic self calibration due to changes in temperature

This function automatically calibrates the balance when the balance detects an ambient temperature change. If GLP output is selected in the function table, the balance outputs the calibration report or stores the data in memory. Automatic self calibration functions even if the display is turned off (standby state). Refer to " 9.1. Permit Or Inhibit" for the operation.

Caution

Place nothing on the weighing pan during automatic self calibration.

If something is on the weighing pan, the balance decides that it is in use and does not perform automatic self calibration.

When weighing a light sample, using long term weighing, installing the balance in a system or considering the importance of the continuous data, turn off automatic self calibration.

Note When turning on the balance with nothing on the pan, if a sample heavier than 0.5 g is placed on the pan, the balance detects the state that a sample is placed on the pan and does not perform the automatic self calibration.

The mark is " prior notice indicator of automatic self calibration".

When the balance detects a change in ambient temperature, this indicator blinks and automatic self calibration is required. If the balance is not used for several minutes with this indicator blinking, the balance performs automatic self calibration.

The environment will affect the time that the indicator blinks.

The balance is measuring calibration data. Do not allow vibration or drafts to affect the balance while this indicator is displayed. After calibration, the balance returns to indicate the previous display.

Advise

The balance can be used while the indicator blinks. But, it is recommended that to maintain the accuracy, stop using the balance and confirm that there is nothing on the pan and allow the balance to perform self calibration.

Cond 0 This parameter is for sensitive response to the fluctuation of a mass value. Used for powder target mass, 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 mass value from drifting due to vibration or drafts. After setting, the balance displays SLOW .

Notes In automatic response adjustment, this parameter is selected automatically.

BM series 47

Stability band width ( 5t-b )

This item controls the width to regard a mass value as a stable value. When the fluctuation per second is less than the parameter, the balance displays the stabilization indicator and outputs or stores the data. The parameter influences the "Auto print mode".

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

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

Display Hold Function ( ploc )

This function is used to measure the volume dispensed from the pipette.

When specifying "Display lock function is used" (ploc on) in the function table, dispensing liquid into the weighing bottle from the pipette and getting a stable weighing value, the balance calculates an average value and displays the result (a fixed value).

When using this function for the measurement of a small volume, the influence of water evaporation can be reduced.

Caution Even if using the weighing bottle (evaporator trap) to reduce the water evaporation, at least 0.05 mg (0.05

Used for weighing a very light sample. trc 1 The normal tracking function is used. trc 2 The strong tracking function is used. trc 3 The very strong tracking function is used. Used for stable zero display.

Display refresh rate ( 5pd )

The periodic time to refresh the display. This parameter influences "Baud rate", "Data output pause" and the data output rate of "Stream mode".

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.

Connection to a computer using the RS-232C Interface

Features

The balance is of the DCE type (Data Communication Equipment), which can be 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).

Using Windows Communication Tools Software (WinCT)

When Windows is used as an operating system in a personal computer, the WinCT software can be used to transmit the weighing data to the personal computer. The current version of the WinCT can be downloaded from the A&D website. Confirm the windows version supported by this software when downloading. Refer to the WinCT instruction manual in the A&D website. The

WinCT software has three communication methods: "RsCom" , "RsKey" and "RsWeight".

RsCom

RsCom can transmit commands to control the balance.

RsCom can make bi-directional communication between the balance and a personal computer using the RS-232C interface.

RsCom can display or store the data using a text file format. RsCom can also print the data using a printer connected to the personal computer.

When several ports of a personal computer have balances connected, the personal computer can communicate with each balance simultaneously.

RsCom can share a personal computer with other application software.

RsCom can receive the balance GLP report.

RsKey

RsKey can transmit the weighing data output from the balance directly to other application software such as Microsoft Excel.

RsKey can be used with most application software.

RsKey can receive the balance GLP report.

Rs weight

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:

Analyzing the weighing data and the statistics input by "RsKey"

The weighing data can be input directly into an Excel worksheet. Then, Excel can analyze the data to obtain total, average, standard deviation, maximum and minimum value, and display them in a graph.

Controlling the balance using commands from a personal computer

By using "RsCom", the personal computer sends commands such as "re-zero" or "send weighing data" to the balance and controls the balance.

Printing the balance GLP report using your printer

The balance GLP report can be printed using a printer connected to the personal computer.

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.

Using the balance memory function

The data can be stored in the balance’s memory. Of the data stored, the weighing data and calibration data can be transmitted to a personal computer at one time.

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.)

76 BM series

Connection to a computer using the USB Interface

Features

The weighing data can be transmitted to a personal computer when connecting the balance and personal computer by the USB interface. The operation system must be Windows 98 or a later version.

The USB interface uses standard device driver software and does not require installation of special driver software. When simply using the USB interface and cable, weighing data can be transmitted.

The data can be transmitted to most application software (ex.: EXCEL, WORD, note pad).

Cautions

The balance can transmit the weighing data without the header and unit.

The USB Interface of the balance can not receive the command that controls the balance.

When using the command, connect to the RS-232C interface of the balance. When connecting the USB Interface of a personal computer to the RS-232C interface of the balance, use the USB converter (AX-USB-9P).

Do not use the screensaver or suspend mode of a personal computer.

Using the USB Interface

1 Start the Windows of the personal computer.

Connect the AC adaptor to the balance and turn on the display with the ON:OFF key.

2 Connect the personal computer to the balance using the USB cable.

Note: Do not use stream mode of data output mode ( dout, prt 3 ).

3 At the first connection only, the USB driver software is automatically installed.

4 Open the application (ex.: EXCEL) that is to receive the weighing data.

Move the cursor onto the position to input the weighing data.

5 Press the PRINT key to input the weighing data at the position of the cursor.

6 When finishing the operation, remove the USB cable.

Examples

Case 1: Transmitting the weighing data with key operation

Data output mode of the balance: Key mode (factory settings),

Acknowledge Code And Error Codes

When the "Serial interface function ( 5if )" parameter is set to " erCd on ", 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 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.

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

Among commands to control the balance, the following transmit the acknowledge code both when the balance receives the command and when the balance has accomplished the command.

If the command can not be processed properly, the balance transmits an error code (EC, E xx ).

This error can be released using the CAL command. xx is error code number.

17.4.

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. If improper performance persists after checking, contact the local A&D dealer for repair.

Checking that the operating environment or weighing method is proper

Operating environment

Is the weighing table solid enough?

Is the balance level?

Is the operating environment free from vibration and drafts?

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

Weighing method

Does the weighing pan rim touch anything? Is the weighing pan assembly 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?

Is the fine range ring installed for weighing with a minimum display of 0.01 mg for the BM-252?

Is the fine range ring, small fine range ring, or slide breeze break installed for weighing with a minimum display of 0.001 mg for the BM-22 and BM-22?

Has the balance been calibrated using the internal mass (one-touch calibration)?

Has the balance been warmed up for one hour 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?

Is the sample charged with static electricity? Is the built-in DC static eliminator (page 29) used to discharge the sample charged with static electricity.

Is the sample of magnetic material such as iron? There are cautions about weighing magnetic materials.

Checking that the balance performs properly

Check the balance performance 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.

Check whether the calibration is performed correctly. If an error occurs and the calibration can not be performed quickly, the balance may not measure correctly.

17.5.

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 and observe the following when transporting the balance.

Use the original packing material for transportation.

AD-1691:Balance environment analyzer

 During the routine inspection, repeatability and the minimum weighing value can be easily checked.

 Also, this calculates measurement uncertainty and supports environmental evaluation of the scale.

 This analyzer can be easily carried to the scale site, so more than one scale can be controlled using this analyzer.

BM series 91

AD-1687: Weighing environment logger

 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 can store environmental data along with weighing data. Therefore, it is possible to store 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.

AD-1688: Data logger

 When connected to the RS-232C interface of the balance, the AD-1688 can store the data in an environment where a personal computer can not be used.

AD-8526: LAN converter

 This option can be used to connect the RS-232C interface of the balance to the Ethernet (LAN) port of a computer. This allows management of the balance weighing data with a computer connected to a network.

AD-8527: Quick USB adapter

AD-8920A: Remote display

 Connected to the GP series using the RS-232C interface.

AD-8922A: Remote controller

 This option can be connected to the balance using the RS-232C interface and can control the balance remotely.

Various options such as comparator output or analog output are available.

AX-USB-9/25P-EX: USB converter

 Adds a COM port to a PC.

 Enables bi-directional communication between the PC and the balance when a USB driver is installed.

 Can use serial communication software such as WinCT on a PC without COM ports.

 An RS-232C cable is provided to connect the USB converter to the balance.

AD-1671: Anti-vibration table

 Approximately 24kg, Artificial stone (Terrazzo).

 Use this table when unstable weighing is caused by vibration coming from the floor.

 Use the AD-8922A remote controller to avoid a weighing error by a slight table tilt that key operation may

make.

AD-1672: Tabletop breeze break

 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.

AD-1683 : Ionizer

 This ionizer eliminates static electricity to prevent weighing errors caused by electrification during measurement.

 This direct current and windless type is the most suitable for precisely weighing powder, etc.

 Small size, light weight

AD-1684A: Electrostatic field meter

 This option measures the amount of the static charge on the sample, tare or peripheral

equipment and displays the result.

 If those are found to be charged, discharge them using the AD-1683 DC static eliminator.

AD-1682: Rechargeable Battery

 This option allows use of the balance in a place where AC power is not available.

AD-1689: Tweezers for calibration weight

 This option is the same as the tweezers provided as a standard accessory and is used when

calibrating the balance using an external weight.

92 BM series

AX-SW137-PRINT: Foot switch print function with plug

 The foot switch has the same function as the "PRINT"key.

AX-SW137-REZERO: Foot switch rezero function with plug

 The foot switch has the same function as the "REZERO"key.

Repeatability Variation in measured values obtained when the same mass is placed and removed repetitively. Usually expressed as a standard deviation.

Example: "Standard deviation = 1 digit " means that may occur a weighing error within

±1 digit in the frequency of approx. 68% when weighing the same mass repeatedly.

Re-zero To set the display to zero.

Sensitivity drift An affect that a change in temperature causes to the weighing data.

Expressed as a temperature coefficient.

Example: Temperature coefficient = 2 ppm/°C, If a load is 10 g and the temperature changes by 10°C, the value displayed changes by the following value.

0.000

002 ppm/°C x 10 °C x 10 g = 0.0002 g

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

Tare To cancel the mass value of a container which is not to be included in the weighing data. Normally, refers to an operation of placing a container and setting the display to zero.

Target mass

Zero point

An external weight used for calibration test

A weighing reference point. Usually refers to the value displayed when nothing is on the weighing pan.
