When the balance is built into a system, remove the balance from the system. Place it on a solid table. Install the breeze break and perform checking.

When the balance proper performance is confirmed, refer to page 10 to set up the installation site.

Checking that the operating environment or weighing method is proper

Operating environment

Is the weighing table solid enough

Is the balance level? Refer to “3-1 Before Use”.

Is the operating environment free from vibration and drafts? Has the stainless steel breeze break been installed?

Is there a strong electrical or magnetic noise source such as a motor near the balance? Is there a heat source near the balance?

Weighing method

Does the weighing pan touch the breeze break or anything? Is the weighing pan installed correctly?

Is the RE-ZERO key pressed before placing a sample on the weighing pan? Or, is RE-ZERO performed using external contact input or an RS-232C command?

Is the sample placed in the center of the weighing pan?

Has the balance been warmed up for the appropriate duration before weighing? AD-4212A series balance: 30 minutes or more

AD-4212B series balance: one hour or more

Are the leveling feet of the weighing unit placed flat to the installation surface?

If not, the weight value will be unstable or the specified repeatability can not be obtained. Improve the installation condition, by securing the weighing unit or reducing the vibration that is conveyed to the weighing unit.

Sample and container

Has the sample absorbed or lost moisture due to the ambient conditions such as temperature or humidity?

Has the temperature of the container been allowed to equalize to the ambient temperature? Refer to “3-2 When Building into a System”.

Is the sample charged with static electricity? Refer to “3-2 When Building into a System”.

Is the sample of magnetic material such as iron? Use much care when weighing magnetic materials. Refer to “3-2 When Building into a System”.
