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.
