Question

) In the figure given, R2 is a resistive sensor with R2=R20(1+x) (x: measurand,
: constant coefficient, R20 =2k6). The internal resistance of the 3 ½ digit
auto-range digital V-meter (DVM) is assumed to be infinite.
The absolute error of the DVM is given as:
ΔU = ± (0.05% of the reading + 0.04% of the range) [V]
a) With =1, what are the readings on the display of the DVM for x=0 and
x=0.25?
b) The tolerances of all the resistors are given as 1%. For x=0, calculate the absolute uncertainty in the
reading at 95% confidence level. (Individual uncertainties are assumed to be uncorrelated)
