2-3 Installing the Balance
Install the balance as follows:
1. Refer to “3-1 Before Use” for installing the balance. Place the balance on a solid weighing
table.
2. Assemble the balance as shown in “2. UNPACKING THE BALANCE”.
3. Adjust the leveling feet to level the balance. Confirm it using the bubble spirit level.
4. Confirm that the adapter type is correct for the local voltage and power receptacle type.
5. Connect the AC adapter to the balance. Warm up the balance for at least 30 minutes with
nothing on the weighing pan.
3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weighing data, note the
following:
3-1 Before Use
zThe MC series is a high-precision balance with a resolution of
1/10000000. It is prone to changes in temperature and
pressure, static electricity, drafts and vibration of the installation
site. During calibration using an internal mass, it resolves up to
one digit lower than the minimum weighing value. Therefore, be
sure to place the balance in a stable environment.
zThe best operating temperature is about 20°C±2°C at 45-60%
relative humidity.
zInstall the balance where it is not exposed to direct sunlight and
it is not affected by heaters or air conditioners.
zInstall the balance where it is free of dust.
zInstall the balance away from equipment which produces
magnetic fields.
zInstall 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.
zThe weighing table should be solid and free from vibration,
drafts and as level as possible.
zLevel the balance by adjusting the leveling feet and confirm it
using the bubble spirit level.
zIf static electricity is a problem at the installation site, use the
electrostatic field meter and the static eliminator.
zEnsure a stable power source when using the AC adapter.

11
zWarm up the balance for at least 30 minutes. Plug in the AC
adapter as usual.
zCalibrate the balance periodically for accurate weighing.
zBefore using the balance for the first time or after having moved
it to another location, warm up the balance for six hours or
more to allow the balance to reach equilibrium with the room
temperature, and then calibrate the balance.
Caution
Do not install the balance where flammable or corrosive gas is present.
3-2 During Use
zStatic charge may cause weighing errors. When the
ambient humidity is less than 45% RH, insulators such as
plastic or glass are prone to static electricity. Discharge
static electricity from the material to be weighed
(hereinafter referred to as sample). Ground the balance
and try the following:
Eliminate the static electricity by using an optional
static eliminator, AD-1683,
Or try to keep the ambient humidity above 45%RH.
Or use a metal shield case.
Or wipe a charged plastic sample with the wet cloth.
zThis balance uses a strong magnet as part of the
balance assembly, so please use caution when
weighing magnetic materials such as iron. 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.
zCancel the temperature difference between a sample, tare and the environment. When a
sample is warmer (cooler) than the ambient temperature, the sample will be lighter (heavier)
than the true weight. This error is due to a rising (falling) draft around the sample.
zMake each weighing gently and quickly to avoid errors due to changes in the environmental
conditions.
zDo 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.
zDo not use a sharp instrument such as a pencil to press the keys. Use your finger only.
zPress the RE-ZERO key before each weighing to prevent possible errors.
zTake into consideration the affect of air buoyancy on a sample when more accuracy is
required.
zKeep the balance interior free of dust and foreign materials.

12
3-3 After Use
zAvoid mechanical shock to the balance.
zDo not disassemble the balance. Contact the local A&D dealer if the balance needs service or
repair.
zDo 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.
zProtect the internal parts of the balance from liquid spills and excessive dust.
3-4 Power Supply
zDo 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, press the ON:OFF key and confirm that zero is displayed.
zWhen 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, warm up the balance for at least 30
minutes before use.

5. WEIGHING
5-1 Selecting the Weighing Units (Modes)
The unit “g” (gram) was set at the factory.
To use other units, select and store units and displaying order in the function setting of “ Unit ”.
For details on weighing unit selection procedure, refer to the GX series instruction manual, “5.
WEIGHING UNITS”.
5-2 Basic Weighing
When using as a mass comparator
zTo reduce the influence of drafts and vibration, set the following function settings as below.
“Condition ( Cond )” of “Environment, Display ( ba5fnc )” to “Slow ( 2)”
“Filter ( f1l )” of ““Environment, Display ( ba5fnc )” to “Used (1)”
For details, refer to “9. FUNCTION TABLE”.
zTo avoid eccentric loading errors, place the sample in the center of the weighing pan.
As an option, auto-centering pans are available: AX-MC1000PAN for the MC-1000 and
AX-MC6100PAN for the MC-6100.
Using an AD-8922A remote controller, which is sold separately, the balance can be controlled
remotely by the AD-8922A key operations in the same way as when the CAL or
RE-ZERO key of the balance is pressed. For the connection procedure between the balance
and the AD-8922A, refer to the AD-8922A instruction manual.
zTake measures against causes of weighing error at the installation site, such as changes in
temperature, atmospheric pressure, drafts, vibration and static electricity. Perform weighing
operations in a stable environment.
zThe table below lists the weight class and recommended measuring range for each model of
the MC series. The measuring range is determined so that the balance repeatability is to be
less than one third of the maximum permissible error for each weight class.

When building into a system
zWhen a special weighing pan is to be designed, the weight of the pan and the material to be
weighed should not exceed the weighing capacity of the balance.
To reduce influences of static electricity and magnetism, use materials other than resin and
magnetic material such as iron.
zThere is a function available to maintain the previous weight value in non-volatile memory,
even if the AC adapter is removed.
When “Zero upon power-on ( p-tr )” of “Environment, Display ( ba5fnc )” is set to “ 1”, the
previous weight value is displayed upon power-on.
For details, refer to “Zero upon power-on” on page 33.
zThere is a function available to perform span calibration only, when performing calibration with
a tare on the weighing pan.
When “Span calibration ( 5pn )” of “Environment, Display ( ba5fnc )” is set to “ 1”, span
calibration using the internal mass is performed, with a tare on the weighing pan.
For details, refer to “Span calibration” on page 33.
zTo set a higher response rate or to batch-weigh small amounts of material, such as a powdery
material, refer to “14. EXTENDED FUNCTION”.

16
6. RESPONSE ADJUSTMENT / SELF CHECK FUNCTION
This function detects the influence on weighing that is caused by drafts and/or vibration at the place
where the balance is installed and sets the response characteristic automatically. When this function
is selected, the balance self-checks the performance at the same time.
Two modes of response adjustment are available: automatic and manual.
The function has three rates as follows:
Changing the response rate changes the display refresh rate.
Indicator Parameter Response characteristic Display refresh rate
FAST Cond 0
MID. Cond 1
SLOW Cond 2
Fast response, Sensitive value
Slow response, Stable value
If the response rate is changed as follows:
MID. or SLOW FAST =10 times/second
FAST MID. or SLOW = 5 times/second
Note
To set the refresh rate of 5 times/second when the response rate is FAST or 10 times/second
when the response rate is MID. or SLOW, change the “Display refresh rate ( 5pd )” parameter
of “Environment, Display ( ba5fnc )” in the function table. For details, refer to “9. FUNCTION
TABLE”.
6-1 Automatic Response Adjustment / Self Check Function
This function automatically updates the response adjustment by analyzing the influence of the
environment on the weighing data and also self-checks the balance performance using the internal
mass.
Operation
1 Press and hold the MODE key until RESPONSE is
displayed, then release the key.
2 The balance automatically starts to check the balance
performance and sets the response characteristic.
Caution
