Introduction
Introduction Introduction
The AD-4407 is a weighing indicator that amplifies signals from a load cell,
converts it to digital data and displays it as a mass value.
This indicator has the following performance:
Input sensitivity: ......................... 0.25 mV /division.
Maximum display: ...................... 40000 divisions.
Refresh rate of the display: ........ 10 times/second approximately.
Input voltage range: ................... -1 mV ~ +15 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.
There are four code memories to store the above mentioned data.
The accumulation function to totalize these 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.
0 9
IP-67 dust & water-proof stainless housing.
There are the following interfaces:
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.
RS-422/485 and 3-Relay Outputs (Option: OP-03)
RS-232C, 3-Relay Outputs and 3-Control Inputs (Option: OP-05)
RS-232C, Current Loop Output, 3-Relay Outputs and 1-Control Input (Option:
OP-08)
Analog Output (4-20mA) (Option: OP-07)
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.
