Precautions
Before Use

To ensure that you get the most from your balance, please try to follow these conditions as
closely as possible.
Please confirm that the AC adapter type is correct for your local voltage and receptacle type.
Ensure a stable power source when using the AC adapter.
The best operating temperature is about 20°C / 68°F at about 50% Relative Humidity.
The weighing room should be free of dust.
The weighing table should be solid and free from vibration, drafts (such as frequently
opening doors or windows) and as level as possible.
Corners of rooms are best as they are less prone to vibration.
Do not install the balance near a heater or air conditioner.
Do not install the balance in direct sunlight.
Do not use the balance near other equipment which produces magnetic fields.
Keep the balance level by using the bubble spirit level.
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.
Do not place or use the balance where there is flammable or corrosive gas present.

3.2.

During Use

Note the following items to get accurate weighing data.
Metal case
Discharge static electricity from the weighing material.
Charged material
When a weighing sample (plastics, insulator, etc.)
could have a static charge, the weight value isinfluenced. Ground the balance, andEliminate the static electricity using the optional AD-1683.
Try to keep the ambient humidity above 45%RH.
Use a metal shield case.
GroundingWipe a charged plastic sample with a damp cloth.

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 (on the bottomof the balance) to suspend the material away from the influence ofthe magnet.

Eliminate the temperature difference between the weighed sample
and the environment. When a sample is warmer (cooler) than theambient temperature, the sample will lighter (heavier) than truemass. This error is due to the rising (falling) draft around thesample.

Counting Mode (PCS)This is the mode to determine the number of objects in a sample based on the standard
sample unit mass. The unit mass means an average mass of the samples. The smaller thevariation in the samples, the more accurate the count will be. The balance is equipped with theAutomatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Notes
Use samples with a unit mass of 1 mg or more 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 thesamples into several groups and count each group.

13.2.3. Connecting to a Computer Using the RS-232C

Interface
Features

The balance is of the DCE type (Data Communication Equipment), which can beconnected to a personal computer using the RS-232C interface. Before connection,
read the personal computer manual thoroughly. Use a standard DCE cable forconnection (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 thewindowsversionsupportedby
thissoftwarewhen
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 thedata 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 otherapplication software such as Microsoft Excel.
RsKey can be used with most application software.
RsKey can receive the balance GLP report.

RsWeight

Can retrieve the weight data from the balance and display the data as a graph in realtime.
Can calculate and display the maximum, minimum, average, standard deviation andcoefficient 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 values, anddisplay 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 "sendweighing data" to the balance and controls the balance.
Printing the balance GLP report using your printerThe balance GLP report can be printed using a printer connected to the personal
computer.
48

Receiving weighing data at a certain interval
The weighing data can be received at a certain interval and data characteristic withelapsed 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 dataand 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.)

13.3.2. 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 can not 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 can not process it, thebalance transmits an error code (EC, Exx).
When the balance receives a command to control the balance and can process it, thebalance transmits the acknowledge 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 accomplishedthe command. If the command can not be processed properly, the balance transmits anerror 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)
TR command (Tare command)
TST command (Calibration test command)
When a communication error has occurred due to external noise, or a parity error has
occurred due to a transmission error, the balance transmits an error code. In this case, send
the command again.

xx is error code number.

13.3.3. 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 can not receive the next command(Example: while the balance is processing the last command), the balance sets the CTS line
to Lo. The balance confirms the level 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 datais canceled).

13.3.4. Settings Related to RS-232C

Concerning the RS-232C, the balance has two functions: "Data output (dout)" and "Serialinterface (5if)". Set each function as necessary.

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 withrepeatability 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 breeze break ring installed for weighing with a readability of 0.01 mg for the
HR-202i?
Has the balance been warmed up for one hour before weighing?

Sample and containerHas the sample absorbed or lost moisture due to the ambient conditions such astemperature 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 sample of magnetic material such as iron? There are cautions about weighing
magnetic materials.
