Installation and Precautions

The balance is a precision instrument. Unpack it carefully. Keep the packing material to be used for transporting the balance in the future. The packing contents depend on the balance model. See the illustrations to confirm that everything is contained.

Note

• Please confirm that the AC adapter type is correct for your local voltage and receptacle type.
• Please use the specified dedicated AC adapter for the balance.
• Do not use the included AC adapter for models that are not considered compatible with the AC adapters.
• If you use the wrong AC adapter, the balance and other equipment may not operate properly.

2-1 Precautions
To get the optimum performance from the balance and acquire accurate weighing data, note the following:

• Install the balance in an environment where the temperature and humidity are not excessive.
  The best operating temperature is about 20°C±2°C at about 45 ~ 60%RH relative humidity.

• Install the balance where it is free of dust.

• The weighing table should be solid, free from vibration and drafts, and as level as possible. (An anti-vibration table or stone table is ideal)

• Install the balance in a stable place avoiding vibration and shock. The corners of rooms on the first floor are best, as they are less prone to vibration.

• Install the balance where it is not affected by heaters or air conditioners.

• Install the balance where it is not exposed to direct sunlight.

• Install the balance away from equipment that produces magnetic fields.

• Level the balance by adjusting the leveling feet and confirm it using the bubble spirit level.

• Warm up the balance for at least 30 minutes. Plug in the AC adapter as usual.

• Adjust the sensitivity of the balance before use or after moving it to another location. Refer to the separate instruction manual “7. Sensitivity Adjustment”.

About the GX-AWP/GF-AWP series

• The dustproof and waterproof level of the balance is equivalent to IP65, and its second digit, “5”, corresponds to “having no harmful influence by receiving a direct jet of water”. Washing with strong water pressure or submersion in water may cause water to enter the balance and cause a malfunction.
• When installing and using the balance under conditions requiring dustproof and waterproof performance, make sure that the AC adapter plug is fully inserted into the AC  adapter jack and that the terminal cover is attached to the RS-232C interface or the waterproof RS-232C cable (AXKO2737-500) is used.
• If the RS-232C terminal cover is removed or the waterproof RS-232C cable (AX-KO2737-500) is not used, protection against dust and water is not provided.

Caution
Do not install the balance where flammable or corrosive gas is present.
