Simply set the no load analog output, then flip a switch and adjust the full scale output with the rotary encoder and you are all set. If the load cell is a Wheatstone bridge, the bias return path is established through the bridge unless the bridge and the amplifier supplies are isolated from each other. The high retention USB connector ensures that the power supply to the IDA100 digital load cell ADC will not be jeopardized should the connector experience a tug or pull during use. This strain gauge load cell amplifier also has a software selectable ±5V and ±10V analog output with a low noise value of 12 mVp-p (millivolt peak-to-peak) and a bandwidth of 1 kHz. In order to do so, the mV/V low amplitude output of the load cell goes thru four different signal conditioning steps: 1) Excitation Voltage: Full-bridge load cells or torque sensors require an excitation voltage from the Wheatstone bridge amplifier to feed the strain gage Wheatstone bridge and generate their output signal as a ratio of the input excitation voltage. I guess it could be done without HX711. Noise needs to be filtered out before you can capture an accurate signal. 4 channels amplifier with aluminum alloy shell, could connect four load cells and send out analog output, the internal use of imported high-performance devices. 0-10V or 4-20mA).
