After Use; Power Supply - A&D GX-203A Instruction Manual

Cancel the temperature difference 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 error is due to a rising (falling) draft around the sample.
□ Make each weighing gently and quickly to avoid errors due to
changes in the environmental conditions.
□ When placing a sample on a weighing pan, do not give a strong
shock or do not exceed the weighing capacity. And place in the
center.
□ 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.
□ 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.

2-4 After Use

□ Avoid mechanical shock to the balance.
□ 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.

2-5 Power Supply

□ When the AC adapter is connected, the balance is in the standby mode if the standby indicator is on.
This is a normal state and does not harm the balance. For accurate weighing, keep the AC adapter
connected to the balance and AC power unless the balance is not to be used for a long period of
time.
