Error accuracy calculation
Thread Content
If the actual temperature of the variable being measured is 500°C, and a temperature measuring instrument reads 502°C, with a measurement range of 0–600°C, then which of the following values is the correct answer? ( ) A. Relative error of 0.4% B. Maximum relative percentage error of 0.33% C. Instrument accuracy of 0.2 D. Measurement accuracy of 250. The answer is ABD. How is this calculated? Please show the process
I don’t understand answer D. A: (502-500)/500 = 0.4%; B: (502-500)/600 = 0.33%
D. A measurement accuracy of 250 – that’s obviously wrong; is such an accuracy even possible?
