Perfect compatibility with AD-4401
> The size, color, method of operation and installing to a control panel of the AD-4401A remains the same as the AD-4401.
> Interface connectors retain compatibility so even when updating from AD-4401 to AD-4401A previously connected devices can continue to
be used without changing any connectors.
> Functions have been added but the default settings remain identical to the AD-4401.

> High-Performance Digital Filter (HPDF) for Environments with Vibration Issues
> The High-Performance Digital Filter provides high accuracy/high speed weighing in environments with vibration > problems.
> It greatly reduces the costs and maintenance required for anti-vibration equipment since it copes with vibrations without requiring many
mechanical measures. What’s more, conducting weighing while applying vibrations, once an extremely difficult task, is now possible.
