2-2 Installing the Balance
Caution
The weighing unit and the display unit were adjusted as a unit. Therefore, make sure that
the weighing unit and the display unit have the same serial number. The serial number is
printed on the rear of the weighing unit and the display unit. The connection cable also
carries the serial number.
If the serial numbers of both units are different, the balance may not function properly.
When a repair is necessary, submit both the weighing unit and the display unit for repair.
There is no compatibility between The AD-4212A and the AD-4212B or AD-4212, for both the
weighing unit and the display unit.

3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weighing 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 AD-4212A/B series balance responds even to very subtle
air flow. To avoid the influence of ambient air flow or air flow
caused by balance operation, make sure to use the dust
guard and the breeze ring (AD-4212B-101/102 only).
Level the weighing unit by adjusting the leveling feet
and confirm it using the bubble spirit level.
If the leveling adjustment is difficult to perform due to
the installation conditions, perform calibration using a
calibration weight or controlled actual sample before
weighing.
Ensure a stable power source when using the AC
adapter
Warm up the balance for the appropriate duration. Plug
in the AC adapter as usual.
• AD-4212A series balance: 30 minutes or more
• AD-4212B series balance: one hour or more
Calibrate the balance before use or after having moved
it to another location.
In addition, calibrate it periodically to maintain the accuracy.
Caution
Do not install the balance where flammable or corrosive gas is present.
10
3-2 When Building into a System
The AD-4212A/B is a precision balance. When it is built into a system and used, errors such as
unstable weight values may occur due to static electricity, vibration and materials used for the
devices near the balance.
When using the balance that is built into a system, take the following precautions.
Errors due to a static charge
When the ambient humidity is less than 45% RH, insulators such as plastic or glass are prone to
static electricity. When charged material comes close to the balance, a pulling force is generated
between the charged material and the weighing pan. This causes an unstable weight value.
To protect the balance against a discharge generated by charged material when it comes
close to the balance, make sure to earth ground the weighing unit and the display unit.
(Static electricity generated by static induction will not be canceled by earth-grounding.)
Charged plastic breeze break
The pulling force
makes the weight
value unstable
Measures to take (Plastic is used in the measures below. They can be applied to glass, too.)
A pulling force generated between
the charged sample and the balance
causes an unstable weight value.
When the sample or devices are plastic
Use a static eliminator that generates no air blow such as the
Charged
material
AD-1683, DC static eliminator, to remove static electricity.
Place the sample in a container that is made of a conductive
material such as metal and that can be sealed and weigh it.
Metal case
When the sample is powdery
When the balance is used in combination with a feeder for
batch weighing of powdery samples, samples may be
charged by rubbing sample particles against each other.
Use a static eliminator and perform weighing while removing
static electricity.
Grounding
When the sample container is made of material that is prone to static electricity such as plastic
Cover the outside of the container with a metal such as aluminum foil.
Apply an anti-static agent onto the container.
When making a breeze break using plastic
Apply an anti-static agent onto the breeze break.
Use a conductive acrylic fiber.
When plastic exists in the balance installation site
Cover the plastic with a grounded metal.
Apply an anti-static agent onto plastic.
11
When an operator is static charged
If an operator’s clothes are static charged, especially in winter, it may be a cause for
unstable weight values.
Wear an anti-static wrist strap.
Errors due to air flow
Where the influence of ambient air flow is great
such as: close to an air conditioner, door or
passage way. Even very subtle air flow that is
hard to be detected may influence the weighing
operation.
Avoid those areas as a weighing site.
Influence of the air flow
makes the weight
value unstable
If weighing is to be performed in such an
area, use a breeze break or take other
appropriate measures.
Where the influence of heat or drafts is great
Eliminate temperature differences 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
Draft
40 C
20 C
error is due to a rising (falling) draft around
the sample.
Do not touch the sample directly with your
hand. Use tweezers or other tools.
If you touch the sample, the same type
error described above will occur.
Do not perform weighing where it is exposed to direct sunlight. Weighing errors may
occur due to sudden temperature change or drafts.
Where the influence of vibration is great, such as:
(1) Soft ground (2) Second or higher floor (3) Near center of a floor far from pillars (4) Seismic
isolated structures (5) Near tall buildings.
In the areas listed above, the scale may yield unstable weight values on windy days or after an
earthquake. Especially in case of (4) and (5), weight values may be unstable during and for a
long period of time after strong winds or an earthquake.
Errors due to other causes
Change in temperature or humidity
A sudden change in temperature or humidity can generate a draft and cause the balance to
absorb or exude moisture, which leads to weighing errors.
Avoid sudden change in temperature or humidity.
Use an air conditioner to control the temperature or humidity.
12
Magnetic material
The balance uses a strong magnet as part of the balance assembly, so use much care when
weighing magnetic materials.
Place a non-magnetic object such as aluminum or brass between the sample and the
balance, also keep an appropriate distance between them while weighing.
3-3 During Use
To minimize the affect by electrical noises, earth ground
the weighing unit and the display unit.
Make each weighing gently and quickly to avoid errors
due to changes in the environmental conditions.
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
prevent possible errors. In addition, a RE-ZERO signal
can be sent using external contact input/RS-232C
command.
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.
3-4 After Use
Avoid mechanical shock to the balance.
Calibrate the balance, using a calibration weight, periodically.
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.
Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid
spills and excessive dust.
3-5 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 OPERATION”). This is a normal state and
does not harm the balance. For accurate weighing, plug in the AC adapter and warm up the
balance for the appropriate duration before use.
