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?

• A. 3,000
• B. 9,000
• C. 7,942
• D. 22,000

Answer: (C)

To determine the corresponding measurement for a device with a 4-20 mA output that shows a reading of 6 mA within a scale of 0-63,535, it's essential to understand the relationship between the current output and the measurement range. The 4-20 mA current loop operates on the principle that 4 mA represents the lower limit of the scale (0 in this case) and 20 mA represents the upper limit (63,535). To find the measurement corresponding to a 6 mA output, we first need to calculate the span of the scale, which is the difference between the maximum and minimum values: Maximum value = 63,535 Minimum value = 0 Span = 63,535 - 0 = 63,535 Next, calculate the percentage of the output signal above the minimum (4 mA): Current output = 6 mA Minimum signal = 4 mA Difference = 6 mA - 4 mA = 2 mA Now, to find the percentage of the output within the overall range: Percentage = (Difference / (20 mA - 4 mA)) * 100 Percentage = (2 m

To determine the corresponding measurement for a device with a 4-20 mA output that shows a reading of 6 mA within a scale of 0-63,535, it's essential to understand the relationship between the current output and the measurement range.

The 4-20 mA current loop operates on the principle that 4 mA represents the lower limit of the scale (0 in this case) and 20 mA represents the upper limit (63,535). To find the measurement corresponding to a 6 mA output, we first need to calculate the span of the scale, which is the difference between the maximum and minimum values:

Maximum value = 63,535

Minimum value = 0

Span = 63,535 - 0 = 63,535

Next, calculate the percentage of the output signal above the minimum (4 mA):

Current output = 6 mA

Minimum signal = 4 mA

Difference = 6 mA - 4 mA = 2 mA

Now, to find the percentage of the output within the overall range:

Percentage = (Difference / (20 mA - 4 mA)) * 100

Percentage = (2 m
