AD-4407A Weighing Indicator
2. Introduction
The AD-4407A is a weighing indicator that amplifies the signal from a load cell,
converts it to digital data and displays it as a mass value.
This indicator has the following performance:
Input sensitivity: .................. 0.15
µ
V/division.
Maximum display: ............... 40000 divisions.
Refresh rate of the display: . 10 times/second approximately.
Input voltage range: ............ -35 mV ~ +35 mV.
The following standard functions are available:
The HiHi / Hi / OK / Lo / LoLo limit comparison to check a mass value.
The setpoint comparison for batching applications.
The counting function for piece counting.
The preset tare function.
Four code memories to store the above mentioned data.
The accumulation function to totalize the mass values and to count the
number of accumulations.
The hold function enables weighing a living animal.
UFC (Universal Flex Coms) function to customize the protocol of outputting
data using the serial interface.

keys enables easy operation, such as specifying comparator
values.
IP-65 dust & water-proof stainless housing.
The following interfaces are available as options:
One interface can be installed in the indicator at a time.
An RS-232C serial interface is standard, to communicate with a computer,
printer or a remote display. This interface outputs data and can request
weight data, enter parameters and control the state of the indicator.
OP-03: RS-422/485 and 3-Relay Outputs
OP-05: RS-232C, 3-Relay Outputs and 3-Control Inputs
OP-07: Analog Output (4-20mA)
OP-08: RS-232C, Current Loop Output, 3-Relay Outputs and 1-Control Input
The calibration function includes the following functions:
Setting the minimum division (weighing interval) and the maximum capacity.
Zero and span calibration.
The weighing range function of the multi-interval weighing instrument (scale).
Digital linearization function.
Gravity compensation function.
