How to use the Tabletop breeze break (For BM-5, BM5D, BM-20, BM-22)
Features
T his Tabletop breeze break is used to prevent from ambient drafts due to air conditioning and body motion so as
to reduce weighing error.
Be sure to install this breeze break on the balance, as it is affected by even the slightest wind.
This breeze break is designed for the BM series with most suitable use.
The transparent panel assembly consists of antistatic plastic material, which protects the balance from static
electricity.
The rear panel is equipped the hole that i s used to pass the RS-232C and AC adapter cables through.
How to install
We recommend to install the tabletop breez e break (M) in a
position where the display of the balance can be seen
easily and the balance can be operated properly .
Minimize the opening width A of the slide door as narrow
as possible so as to reduce influence of ambient drafts.
Caution
Do not use organic solvents to clean the breeze break because it may damage the transparency and anti-static
properties of the p anels.
Use a sof t l int free clot h dampe ned wi th warm wate r a nd a mil d de tergent whe n cle aning the br eeze br eak.

Eliminate temperature differences between the weighing sample and
the environment. When a sample is warmer (cooler) than the ambient
temperature, the sample will appear lighter (heavier) than the true

Repeatability is an index of variation in weighing values when the same mass is repeatedly
loaded and unloaded. St andard deviation is generally used for the indicator of repeatability.
The repeatability test measures t he i nt ern al ma ss 10 times a nd dis play s th e s t and ard devi ati on .
Use the repeatability test function to inspect the perform ance of the balance when changing the
environment or when moving the balance to a new l ocat io n.
Example: "Standard deviation = 0.2 mg" means that the results of repeated measurements of the
same mass fall wit hin th e range o f ±0.2 mg at a frequency of about 68%.
Notes
When the password function is used, the repeatability test function is available only when

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.)
Automatic self calibration ------------------------- Automatically adjusts the balance using the internal mass
depending on the temperature change of the operating

The underhook can be used for magnetic materials or density measurement. The built-in
underhook is revealed by removing the cap on the bottom of the balance. Use the underhook as
shown bel ow.
Caution
Do not apply excessive force to the underhook.
When not in use, attach the cap to prevent dust from
getting into the balance.
Do not push the underhook upward
When turning the balance over, parts and weighing
sample in the weighing chamber will fall off. (Parts: the
weighing pan, pan support, breeze break ring, fine range
ring and dust plate )
Remove them first .
When the cap is removed, a weighing error may occur,
because of drafts entering into the internal portion of the
balance. Arrange the room condition.

Connecting to a Computer Using the RS-232C Interface
Features
Using Windows Communication Tools Software (WinCT)
RsCom
RsKey
RsWeight
Using the WinCT software, the balance can do the following:
The balance is of the DCE t ype (Data Communi cation Equi pment), 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).
When Windows is used as an ope rat in g 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 w hen downl oa ding. Refer to the WinCT instruction manual in the A&D website. The
WinCT software has three communication methods: "RsCom" , "RsKey" and "RsWeight".
RsCom can transmit commands to control the balance.
RsCom can make bi-directional communication between the balance and a personal computer
using the R S-232C inter fac e .
RsCom can display or store the data using a text file format. RsCom can also print the data using
a printer co nnecte d to th e perso nal co mput er.

The weighing dat a ca n be input directly int o an E xcel worksheet. Then, Excel can analyze the data to
obtain total, averag e, standard devi ation, maxi mum and minimum v alues, and display them in a g raph.
Controlling the balance u sing comma nds from a person al compute r
By using "RsCom", the personal computer sends commands such as "re-zero" or "send weighing
data" to the balance and controls the balance.

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 p er son al com pu ter as an ext ern a l in d icat or
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.)

Connecting to a Computer Using the USB Interface
Features
Using the USB interface
Examples
The weighing data can be transmit ted to a personal computer when connecting the balance and
personal computer via the USB interface. The app licable operating sys tem is Windows 7 or later, as of
December 2018.
The USB interface uses standard device driv er so ftware and do es not r equir e ins tallat ion o f
special driver software. By simply connecting, weighing data can be transmitted.
The data can be transmitted to most application software (ex.: EXCEL, WORD, Notepad).
Notes
The balance can transmit the weighing data only without the header and unit.
The USB interface of t he balance cannot r eceive th e command th at cont rols the balan ce.
When using the command, conne ct to th e RS-232C interface of the balance. When
connecting the USB int erfac e of a personal com puter to the RS-232C interface of the
balance, u se t he USB converter (AX-USB-9P).
Do not use the screen saver or suspend mod e of a p erso nal c ompu t er.

<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 cannot be processed properly, the balance transmits an error code (EC, Exx).
