A&D AD-4212A-100/200/600/1000, AD-4212A/B, AD-4212B-101/102/201/301 1. INTRODUCTION

1. INTRODUCTION

This manual describes how the AD-4212A/B series balance works and how to get the most out of it in

terms of performance.

Read this manual thoroughly before using the balance and keep it at hand for future reference.

 Separate Weighing Unit and Display (standard connection cable length 2 m), suitable for

building into a production line system. The weighing unit is compact, with a width of 80 mm.

 High Resolution and High Response Speed

Model Weighing capacity Minimum weighing value Stabilization time *1

AD-4212A-100 110 g 0.1 mg 1.1 to 1.3 seconds

AD-4212A-200 210 g 0.8 to 1.0 second

AD-4212A-600 610 g

AD-4212A-1000 1100 g

1 mg 0.9 to 1.1 seconds

AD-4212B-101 110 g / 31 g 0.1 mg / 0.01 mg 2.5 / 4.0 seconds *2

AD-4212B-102 110 g 0.01 mg 4.0 seconds *3

AD-4212B-201 210 g

AD-4212B-301 310 g 0.1 mg 2.5 seconds

*1 With FAST selected under good environment

*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 balanc e: 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)
