3. PRECAUTIONS

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

3-1 Before Use

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 which 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 AD-4212A/B series balance responds even to very subtle air flow. To avoid the influence of ambient air flow or air flow caused by balance operation, make sure to use the dust guard and the breeze ring (AD-4212B-101/102 only).

Level the weighing unit by adjusting the leveling feet and confirm it using the bubble spirit level.

If the leveling adjustment is difficult to perform due to the installation conditions, perform calibration using a calibration weight or controlled actual sample before weighing.

Ensure a stable power source when using the AC adapter

Warm up the balance for the appropriate duration. Plug in the AC adapter as usual.

•AD-4212A series balance: 30 minutes or more

•AD-4212B series balance: one hour or more

Calibrate the balance before use or after having moved it to another location.

In addition, calibrate it periodically to maintain the accuracy.

Caution

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