When Building Into a System
The AD-4212C is a precision balance. When it is built into a system, errors such as unstable weight
values may occur due to static electricity, vibration, sample temperature and magnetism of the
materials weighed or used for the devices near the balance.
When using the balance as part of a system, take the following precautions:

Precautions when not performing the weighing at the center of the weighing
pan
If not performing the weighing at the center of the weighing pan, design the weighing system so
that the total moment of the support device and the object to be weighed will be the value
specified in the table below. Even a load, with a moment of less than the specified value, when
applied to the balance, may cause the overload protection mechanism to function slowly, to tilt
the weighing pan.
Allowable eccentric load for each model
Model
Allowable eccentric load
AD-4212C-300/600/301
0.1 Nm or less
AD-4212C-3000/6000/3100
0.3 Nm or less
AD-4212C-300/600/301
Example of a system where the total moment of the device and the object is 0.1 Nm or less:
200 g X 0.05 m
AD-4212C-3000/6000/3100
Example of a system where the total moment of the device and the object is 0.3 Nm or less:
300 g X 0.1 m
Note: The values above are for reference and may be different from actual
specifications.
