The WGI-400A is an Instrumentation Amplifier with multipurpose indicator that measures and displays load,
weight, pressure, displacement, etc. in physical values by connecting to various strain gage transducers such as
load cells, pressure meters, displacement meters, etc.
PRINCIPAL FUNCTIONS
• Calibration Function
Calibration values of transducers (sensors) are registered to display load, pressure, etc. in physical values.
There are 3 calibration functions such as actual load calibration, sensitivity registering calibration, and
numeric value registering calibration.
• TEDS (Transducer Electronic Data Sheet) (hereinafter referred to as the TEDS) Function
With calibration data obtained by TEDS compatible transducers, sensitivity is automatically registered.
• High/Low Limit Comparator Function
The indicated value is compared with the preset high/low limit values and the compared results are
externally output as well as indicated on LEDs.
• Pattern Select Function
Four sets of high/low limit values are stored and selected from the external signal.
• Analog Output Adjusting Function
Capable of adjusting voltage output that is proportional to the indicated value.
• Smoothing Function
The number of moving average times and minimum scale are set to decrease unstable indication.
• Auto Zero Compensation Function
Conduct Zero tracking and zero near zero function to stable the Zero display.
• Level Test Function
Displays arbitrary value to adjust the externally connected devices with ease.
• Optional Function
Various optional functions such as RS-232C, RS-485, and BCD output functions are provided so as to be
easily connected to an external indicator, printer, sequencer, PC, etc.
