The module uses a 4.99Ohm resistor for the load of the 4-20mA interface (Using the INA196 chip):
- 4.99ohm @ 20mA gives a full scale of just under 0.1V
- The device resources tab recommends using the Arduino ADS1115 interface library.
- With a gain setting of 2 the Arduino code comment states : +/-2.048V range = Gain 2.
- The description tab for the device states that with a gain setting of 2 “at 20mA the raw ADC value will be around 32154”. This is not possible at an input voltage of 0.1V.
Can anyone clarify what is incorrect?
