4.Adjust the leveling feet to level the weighing unit. Confirm it using the bubble spirit level.

5.Confirm that the adapter type is correct for the local voltage and power receptacle type.

6.Plug the AC adapter plug into the AC adapter jack located on the rear of the display unit and plug the AC adapter into the electrical outlet. Warm up the balance for the appropriate duration with nothing on the weighing pan.

AD-4212A series balance: 30 minutes or more

AD-4212B series balance: one hour or more

7.Set the pan unit and I/O unit to adapt to the peripheral system. Set the following for the I/O unit. RS-232C (Refer to page 63)

Comparator contact output (Refer to page 64)

RE-ZERO operation using external contact input (Refer to page 64) Auto-display ON function (Refer to pages 29 and 34)

Set the weighing speed to adapt to the ambient conditions.

8.After the balance has been installed, calibrate the balance using the calibration weight provided with the balance. For details, refer to “8. CALIBRATION”.

9.A special weighing pan designed appropriately for the sample to be weighed or the peripheral system can be attached to the balance. About how to design a weighing pan, refer to “24
