11. TROUBLESHOOTING

 Displayed values are unstable.

The AD-4212B-PT / AD-4212A-PT has a minimum weighing value of 0.001 mg / 0.1 mg and is

influenced by the measurement environment.

Measures to take

 Use the accessory breeze break.

 Referring to “3. PRECAUTIONS BEFORE USE”, check the measurement environment for

sources of drafts, vibration and static electricity.

 The AD-4212B-PT with a minimum weighing value of 0.001 mg is prone to low-frequency

vibration such as shaking buildings. Particularly, earthquake, wind and changes in the

barometric pressure influence measurement. To avoid vibration, install the balance on the first

floor, in the corners of rooms (close to pillars or walls) far from a passage way.

 Use the AD-1685 anti-vibration table.

 Use the optional AD-1683 DC static eliminator or use the optional AD-1684 electrostatic field

meter if the cause of the unstable values may be due to static charges.

 Repeatability of the measurement values is low. The measurement values are not correct.

Measures to take

 Referring to “3. PRECAUTIONS BEFORE USE”, check the measurement environment. Using

the accessory calibration weight, measure the balance repeatability and check the balance

performance.

 Referring to “9-3 Example Causes of Measurement Errors”, check the measurement

environment for causes of errors.

 Balance error displays

Refer to the balance instruction manual.
