Features: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.The AD-4401A ensures precise control through an array of timers. When necessary batch weighing settings such as dispense control and supplementary fill are available.Compact size allows for space-saving mounting (Front panel dimensions excluding protrusions: Width 144mm, Height 72mm, Depth 154mm)Displays final weight, accumulated weight, number of accumulations and other function settingsNormal scale calibration generally requires actual weights. However, keying in the specified load cell voltage allows calibration to be performed when using actual weights is not possible.This function allows for the automatic accumulation of net weight when weighing is complete. Correct weights and shortages can be excluded. Accumulated weights and counts are stored in non-volatile memory.This function engages drizzle flow intermittently until the target weight is reached to compensate for insufficient weight. No more worrying about weight shortages again!Featuring a High-Performance Digital Filter for Environments with Vibrations!The HPDF provides high accuracy/high speed weighing in environments with vibrations. It greatly reduces the costs and maintenance required for anti-vibration equipment since it handles vibrations without requiring extensive mechanical vibration countermeasures. What's more, conducting weighing while applying vibrations, once an extremely difficult task, is now possible. There is only one setting for the high performance digital filter. This allows the AD-4410 to find the optimal value to cancel out vibration with only minimal changes to the settings.
