    3.Precautions To get the optimum performance from the balance and acquire accurate weighing data, note the following: 3-1 Before Use The maximum resolution of the precision balance is one million counts. Therefore, there are tendencies to be influenced by temperature change, air pressure change, vibration and drafts where the balance is placed.

  • Page 12: During Use

    3-2 During Use Discharge static electricity from the weighing material. When Material case weighing sample (plastics, insulator, etc.) could have a static Charged sample charge, the weighing value is influenced. Ground the balance, and Eliminate the static electricity by AD-1683 as an accessory. Or try to keep the ambient humidity above 45%RH at the room.

  • Page 13: Power Supply

    Do not allow the balance to be immersed in water. Even though the balance complies with IP code, the balance will not withstand being completely immersed in water. The weighing pan, pan support and draft gate can be removed to clean the balance. Clean by splashing with water.
