  • Page 11: Introduction

    1. Introduction Thank you for choosing the CAS CAUW-D/CAUW/CAUX/CAUY Series analytical balance. CAS confidently offers this high-performance analytical balance, the result of over 80 years of experience in manufacturing precision balances. While providing rapid and accurate mass measurement, reliability has been improved even more by employing the UniBloc cell, introduced for use in electronic balances by CAS in 1989.

Installation 4.1 Installation Site (1) Power Requirements Select an installation site that is near a power source to allow the use of the attached AC adapter or a site where the special accessory battery pack can be properly used. Verify that the power voltage conforms to that indicated on the AC adapter.

    • Sites with extreme temperature changes, or high/ low temperature, or high/low humidity. • Sites near flammable of corrosive gases • Sites with dust, electromagnetic waves, or magnetic fields Install on a sturdy and level tabletop. Stone is recommended. Rather than the middle of the room, the edges and corners are generally appropriate for vibration-free measurement.

    4.4 Turning On the Power Insert the AC adapter plug in to the DC IN connector on the back of the balance. Place the AC adapter cable as shown in figure and hold it with the adapter cable holder. Plug the AC adapter to the power outlet. Clip After the balance performs a self check, calibration will be automatically executed.

  • Page 22: Span Calibration

    4.5 Span Calibration After installation, be certain to complete warm up and span calibration. During span calibration, the balance must be left in a very stable condition. To do this, leave the power on at standby (warm up) for an hour or more before performing calibration.
  • Page 23 For CAUY Series Span calibration with external weights . Leave the pan with nothing on, in g display mode. Press the [CAL] key once. “E-CAL” will be displayed. (Example) Press the [O/T] key. The zero display will blink. Stability is confirmed after about 30 seconds and the value of the weight that should be loaded will blink.

  • Page 24: Basic Operation

    5. Basic Operation (Read Chapters 1 to 5 for basic but proper operation of the balance.) Before using the balance, warm up thoroughly (at least one hour) and calibrate. When intending to use the CAUW-D series in the small range (minimum display 0.01mg), warm it up for at least four hours.
  • Page 25 Except when placing or removing items or calibration weights to and from the weighing chamber, keep the glass doors closed unless otherwise described in this manual. Air convection causes measurement error if the temperatures of the weighed item and the chamber are different. In order to avoid this, equalize the temperatures by leaving the item in the extra space within the chamber before weighing.

    5.2 Changing the Unit Display Pressing the [UNIT] key switches display between the registered units, piece counting and specific gravity measurement modes. The units other than 'g', 'pcs', '%' and 'ct' are not registered in the default settings. The units to be used must be registered as described in 12.Units. If the power is turned off and turned on again, the weighing unit will be 'g'.

  • Page 27: For Stable Measurement In Semi-Micro Range(Cauw-D Series Only)

    5.4 For Stable Measurement in Semi-micro Range (CAUW-D series only) The small range (semi-micro range, minimum display 0.01mg) of CAUW-D series dual range balances produces excellent response and stability. However, weighing in the 0.01mg range is generally more subject to the environment and how measurements are performed compared to the 0.1mg range.

    14.2.2 Data Format Data format 1 (“F-dF1” in menu item selection) is the CAS’s standard data format. (See 14.3.3.5) The following is the details of this data format. (1) Basic format An example of data format for a negative weight value (-21.6865g) with delimiter of C/R is shown.
  • Page 87 (iii) When the delimiter “C/R+L/F” is selected (Refer to 14.3.3.2) The delimiter information requires one more character. Therefore one more byte is added after Position No.13 in the above example. Consequently, the data becomes 1 byte longer. (3) Data format in case of “oL” or “-oL” (Overload) The below is the data format for “oL”.
