2-2 Installing the Balance
Caution
The weighing unit and the display unit were adjusted as a unit. Therefore, make sure that
the weighing unit and the display unit have the same serial number. The serial number is
printed on the rear of the weighing unit and the display unit. The connection cable also
carries the serial number.
If the serial numbers of both units are different, the balance may not function properly.
When a repair is necessary, submit both the weighing unit and the display unit for repair.
There is no compatibility between The AD-4212A and the AD-4212B or AD-4212, for both the
weighing unit and the display unit.
Install the balance as follows:
1. Refer to “3. PRECAUTIONS” for installing the balance.
2. Refer to "2-1 Unpacking" on the previous page to attach the dust guard, the breeze ring
(AD-4212B-101/102 only), the pan support and the weighing pan on the weighing unit.
The stainless steel breeze break is provided for the AD-4121B series balance and the
AD-4212A-100 as a standard accessory, and for the other models as an option. Use it as
necessary when performing calibration or checking accuracy.
How to install the breeze break
• AD-4212A-100/200 and the AD-4212B series balance
Place the breeze break on the weighing pan so that it fits over the dust guard.

1 Remove the weighing pan and the pan support.
