1. Introduction
This manual describes how the balances of HR-iseries work and how to get the most
out of them in terms of performance. Read this manual thoroughly before using the
balance and keep it at hand for future reference.
1.1. About This Manual
This manual consists of the following five parts:
Basic operation ............................ Describes precautions, the balance's construction and basic operation.
Adapting to the environment ........ Describes response (and stability) adjustment to adapt to the environment
where there is vibration or drafts, the way to maintain weighing precision in
a variation of ambient temperature, calibration and calibration test.
Selecting functions ........................ Describes functions of the balance.
Interface and communication ..... Describes the serial interface used for communicating with a computer that
requests weighing data and controls the balance, and for use with a printer.
Maintenance ................................ Describes maintenance, error codes, troubleshooting, specifications and
options.
1.2. Features
Response adjustment adapting to drafts and/or vibration.
The data adapting to GLP, GMP and ISO can be output using the RS-232C serial interface.
Underhook, for measuring density and weighing magnetic materials.
Multiple weighing units with most of the common units used around the world.
Standard RS-232C serial interface to communicate with a computer. Windows communication
tools software (WinCT) to allow easy communication with a computer using Windows.
The current version of the WinCT can be downloaded from the A&D website.

1.3. Compliance
1.3.1. Compliance With FCC Rules
Please note that this equipment generates, uses and can radiate radio frequency energy.
This equipment has been tested and has been found to comply with the limits of a Class A
computing device pursuant to Subpart J of Part 15 of FCC rules. These rules are designed
to provide reasonable protection against interference when equipment is operated in a
commercial environment. If this unit is operated in a residential area, it may cause some
interference and under these circumstances the user would be required to take, at his own
expense, whatever measures are necessary to eliminate the interference.
(FCC = Federal Communications Commission in the U.S.A.)
1.3.2. Compliance With Directives of CE mark
This device features radio interference suppression, safety regulation and restriction of
Hazardous Substances in compliance with the following Council Directives
Council directive 2004/108/EC EN61326 EMC directive
Council directive 2006/95/EC EN60950 Safety of Information Technology Equipment
Council directive 2011/65/EU EN50581 Restriction of the use of certain Hazardous Substances
The CE mark is an official mandatory European marking.
Please note that any electronic product must comply with local laws and regulations when
sold or used anywhere outside Europe.

2. Unpacking the Balance
Unpack the balance carefully. Keep the packing material to be used for transporting the
balance in the future. See the illustrations to confirm that everything is included.

This ring is an accessory for
the HR-202i. Before weighing
with a minimum display of
0.01 mg, install this ring in
place of the "breeze break
ring" to avoid errors caused
by drafts.

2.1. Installing the Balance
Install the balance as follows:
1 Consider section "3. Precautions " for
installing your balance. Place the balance
on a solid weighing table.
2 Assemble the "Dust Plate", "Breeze Break
Ring" and "Weighing Pan" on your balance.
There is a reference illustration on the
previous page.
3 Adjust the level of the balance using the
leveling feet. Ground the balance chassis
for discharging static electricity if you have
a static problem.
4 Please confirm that the adapter type is
correct for your local voltage and power
receptacle type.
5 Connect the AC adapter to the balance.
6 Calibrate the balance before use. Refer to
"8. Calibration".
3. Precautions
3.1. 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.
Discharge static electricity from the weighing material.
When a 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 optional AD-1683.
Try to keep the ambient humidity above 45%RH.
Use a metal shield case.
Wipe 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 bottom
of the balance) to suspend the material away from the influence of
the magnet.
Eliminate the temperature difference between the weighed
sample and the environment. When a sample is warmer (cooler)
than the ambient temperature, the sample will lighter (heavier)
than true mass. This error is due to the rising (falling) draft around
the sample.
Make each weighing gently and quickly to avoid errors due to
changes in the environmental conditions.
Before weighing with a minimum display of 0.01 mg for the
HR-202i, the "fine range breeze break ring" can be installed in
place of the "breeze break ring" to avoid errors caused by drafts.
Do not drop things upon the weighing pan, or place a weight
beyond the range of the balance on the weighing pan.
Do not use a sharp instrument (such as a pencil or ball point
pen) to press the keys, use your finger only.
