When replacing the weighing pan with the auto-centering pan, be sure to calibrate the balance before weighing. Refer to “7. CALIBRATION”.

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

z The 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.

z The best operating temperature is about 20°C±2°C at 45-60%

relative humidity.

z Install the balance where it is not exposed to direct sunlight and

it is not affected by heaters or air conditioners.

z Install the balance where it is free of dust.

z Install the balance away from equipment which produces

magnetic fields.

z 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.

z The weighing table should be solid and free from vibration,

drafts and as level as possible.

z Level the balance by adjusting the leveling feet and confirm it

using the bubble spirit level.

z If static electricity is a problem at the installation site, use the

electrostatic field meter and the static eliminator.

z Ensure a stable power source when using the AC adapter.

z Warm up the balance for at least 30 minutes. Plug in the AC

adapter as usual.

z Calibrate the balance periodically for accurate weighing.

z Before 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

z Static 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.

z This 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.

z Cancel 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.

z Make each weighing gently and quickly to avoid errors due to changes in the environmental

conditions.

z 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.

z Do not use a sharp instrument such as a pencil to press the keys. Use your finger only.

z Press the RE-ZERO key before each weighing to prevent possible errors.

z Take into consideration the affect of air buoyancy on a sample when more accuracy is

required.

z Keep the balance interior free of dust and foreign materials.

3-3 After Use

z Avoid mechanical shock to the balance.

z Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or

repair.

z 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.

z Protect the internal parts of the balance from liquid spills and excessive dust.

3-4 Power Supply

z Do 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.

z 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, warm up the balance for at least 30 minutes before use.
