Figure 11. Weigh Scale Demo
A load cell can be connected directly to the AD7190/AD7192
evaluation board. When the WeighScale Demo button in the
main window (see Figure 6) is clicked, you are guided through a
series of windows that give information on connecting the load
cell to the AD7190/AD7192 evaluation board. The AD7190/
AD7192 device is automatically configured to have a gain of
128, Channel AIN3/AIN4 is selected, and the output data rate is
programmed to 10 Hz. When the instructions given in each
window are completed, click OK. The AD7190/AD7192
evaluation board gathers samples continuously and uses batches
of 20 samples to analyze the data. The software displays the
maximum voltage measured, the average voltage, the minimum
voltage, the rms noise, and resolution. The sample size used to
process the data can be altered using the Last # Samples box.
