     Ensure a stable power source when using the AC adapter.  Connect the power to the balance using the AC adapter at least one hour before use, but in the case of the AD-4212D-33/32, four hours are required. It is recommended to connecting the power to the balance.

  • Page 14: When Building Into A System

    3.2. When Building Into a System  Errors due to a static charge and measures to take When the ambient humidity is less than 45% RH, insulators such as plastic or glass are prone to static electricity. When charged material comes close to the balance, a pulling force is generated by static induction between the charged material and the weighing pan.
  • Page 15  Wear an anti-static wrist strap.  Errors due to air flow and measures to take Where the influence of ambient air flow is great such as: close to an air conditioner or fan, door or passage way. Even very subtle air flow that is hard to be detected may influence the weighing operation.

  • Page 16: During Use

    3.3. During Use  To minimize the affect by electrical noises, earth ground the weighing unit and the display unit (option).  Do not drop things upon the weighing pan, or place a sample on the pan that is beyond the balance weighing capacity.

  • Page 21: Smart Range Function

    SMART RANGE FUNCTION The AD-4212D-32 is equipped with two ranges. The precision range has a higher resolution. The standard range has a normal resolution. The range switches automatically depending on the value displayed. Touching the RE-ZERO button or sending the R command allows weighing in the precision range regardless of the tare value. The range can be fixed to the standard range by changing the minimum weighing value using the RE-ZERO button or R command.

  • Page 22: Underhook

    UNDERHOOK The underhook can be used for magnetic materials or density measurement. The built-in underhook is revealed by removing the cap on the bottom of the balance. Use the underhook as shown below. Caution Bottom Do not apply excessive force to the underhook. When not in use, attach the cap to prevent dust from getting into the balance.

  • Page 23: Function Table

    FUNCTION TABLE The function table reads or rewrites the parameters that are stored in the balance. These parameters are maintained in non-volatile memory, even if the AC adapter is removed. The function table menu consists of two layers. The first layer is the "Class" and the second layer is the "Item".
