*2 The AD-4212B-101 is equipped with a smart range function. When the minimum weighing value is set to 0.01 mg and the weight value exceeds 31 g, the minimum weighing value will switch to 0.1 mg automatically. Even under this circumstance, pressing the RE-ZERO key tares the value and weighing with the minimum weighing value of 0.01 mg is available up to 31 g.

*3 2.5 seconds when the minimum weighing value is 0.1 mg.

Standard RS-232C Serial Interface / Standard Comparator Contact Output (*4 )

Using the RS-232C serial interface, weighing data can be output to external devices and the balance can be controlled by external devices.

Using comparator contact output, the weight value is compared to the preset upper/lower limit

values and the results are displayed as HI, OK or LO. The buzzer is also available in response to the results.

The RE-ZERO operation is possible using a signal from an external contact input, which allows easy system construction. (This function is only available when the external contact input is installed on the standard interface or OP-01.)

*4 AD-4212A series balance: 3-level output.

AD-4212B series balance: 3-level or 5-level output, switched by the function table setting.

Data Memory Function, storing weighing data, calibration data, unit mass in the counting mode or upper/lower limit values. Once stored, selection of the upper or lower limit value is easy.

Dust-protected and Protected Against Splashing Water (Complying with IP54)
