17-1 Checking the Balance Performance and Environment

The balance is a precision instrument. When the operating environment or the operating method is inadequate, correct weighing can not be performed. Place a sample on the pan and remove it, and repeat this several times. If the balance seems to have a problem with repeatability or to perform improperly, check as described below. If improper performance persists after checking, contact the local A&D dealer for repair.

Checking that the balance performs properly

Check the balance repeatability using an external weight. Be sure to place the weight in the center of the weighing pan.

Check the balance repeatability, linearity and calibrated value using external weights with a known value.

Checking that the operating environment or weighing method is proper

Operating environment

Is the weighing table solid enough (especially for the FX-120i /200i /300i, the balance with a minimum weighing value of 0.001 g)?

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

Is the operating environment free from vibration and drafts? For the FX-120i /200i /300i, has the breeze break been installed?

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

Weighing method

Is the weighing pan installed correctly?

Is the RE-ZERO key pressed before placing a sample on the weighing pan? Is the sample placed in the center of the weighing pan?

Has the balance been calibrated using an external weight?

Has the balance been warmed up for 30 minutes before weighing?

Sample and container

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

Has the temperature of the container been allowed to equalize to the ambient temperature? Refer to “3-2 During Use”.

Is the sample charged with static electricity? Refer to “3-2 During Use”.

The FX-120i /200i /300i is prone to be charged with static electricity when the relative humidity is low. Is the sample of magnetic material such as iron? Caution is required for weighing magnetic materials. Refer to “3-2 During Use”
