Precautions; Before Use - A&D GX-M Series Instruction Manual

3.Precautions

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

3-1 Before Use

The maximum resolution of the precision balance is one million counts. Therefore, there are
tendencies to be influenced by temperature change, air pressure change, vibration and
drafts where the balance is placed.
Install the balance in an environment where the temperature and humidity are not
excessive. The best operating temperature is about 20°C / 68°F at about 50% relative
humidity.
Install the balance where it is not exposed to direct sunlight and it is not affected by heaters
or air conditioners.
Install the balance where it is free of dust.
Install the balance away from equipment that produces magnetic fields.
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.
The weighing table should be solid and free from vibration, drafts and as level as possible.
Level the balance by adjusting the leveling feet and confirm it using the bubble spirit level.
Ensure a stable power source when using the AC adapter.
Connect the AC adapter and warm up the balance for at least 30 minutes.
Calibrate the balance periodically for accurate weighing.
When the balance is installed for the first time or has been moved, warm up the balance for
at least 6 hours to allow the balance to reach equilibrium with the ambient temperature, and
then perform calibration before use.
The meaning of IP-65 is "No ingress of dust. Projected against water jets".
If a powerful water jet is used or the balance is immersed in water, it may cause a damage
that is due to ingress of water.
Confirm that "the plug is inserted firmly into the jack" and "the terminal is covered using the
waterproof cover or the waterproof RS-232C cable (AX-KO2737-500EX)", when using the
balance.
Use the waterproof option cable AX-KO2737-500EX, when the RS-232C interface is used
with IP-65.
AX-KO2466-200, a standard RS-232C cable, is not waterproof or dustproof.
Confirm that the weighing pan does not touch to rim.
Do not install the balance where flammable or corrosive gas is present.
