Consequently, there will be a cur rent flowing through Rs and a resulting voltage drop across Rs . The amplifier has placed a load on the source device. 9. To analyze this circuit, we will first solve for the amplifier input voltage Yj in terms of the source voltage Vs. -o.... Substituting Eq. 6) into Eq. 7), we obtain VL Ideally, we would like the voltage VL to be equal to the gain G times Vs: VL It can be seen that if R L » Ro and Ri » Rs, Eq. 8) will approximate Eq. 9). That is, there will be no loading effects.
B) If it has an accuracy of ±2% of full range for each range, determine the absolute uncertainty of measurement in each case. (c) Determine the relative (percent of reading) uncertainly if, for a measurement of 25 volts, the ranges 30, 300, or 3000 were used. 5 psi when measuring atmospheric pressure. 2% of full-scale reading. What is the expected error in the measurement of 20 psi in psi and in percent of reading? How can you reduce the error produced by this gage? A voltmeter with a range of 0 to 100 V reads 2 V when the leads are shorted together.
10% ) of the equilibrium response. , response time or settling time) should be small compared to the expected time for the measurand to change in an experiment. If the measurand changes in a time comparable to the transient response time, there will be a significant dynamic measurement error. Frequency response is another useful measure of dynamic response. The output of the system is determined for a pure sine-wave input. 10. 10, there is the range of sinusoidal input frequencies over which the measuring system gives a constant ratio of output amplitude to input amplitude.
