If a device with a 4-20 mA output shows a reading of 6 mA, what is the corresponding measurement based on a range of 0-63,535?

To understand why the answer of 19,060.5 is correct, it is important to recognize how a 4-20 mA output signal correlates to a measurement range. The range mentioned in the question is from 0 to 63,535, which indicates the full scale of the measurement the device is designed for.

The 4-20 mA signal represents a linear relationship between the output current and the measurement range. The 4 mA corresponds to the minimum value of 0, and the 20 mA represents the maximum value of 63,535. To find the measurement corresponding to a current reading of 6 mA, we first need to calculate the span of the signal, which is the difference between the maximum and minimum values of the output (20 mA - 4 mA = 16 mA).

Next, we need to determine the equivalent measurement for a signal of 6 mA. First, subtract the minimum current (4 mA) from 6 mA to find the amount of current above the minimum:

6 mA - 4 mA = 2 mA.

Now, we need to determine what fraction of the total range this 2 mA represents in
