What is r0 - ANSWERoutput range
uncertainty in a measurement is the result of - ANSWERcombination of random and
systematic error
Which one is correct - ANSWERsystematic error is modifiable
the history of using a measurement system can be effective on this error -
ANSWERhysteresis error
in a calibration test, 10 measurement using a digital voltmeter have been made of
the voltage of a battery that is known to have a true voltage of 6.11 V. The readings
are: 5.98, 6.05, 6.10, 6.06, 5.99, 5.96, 6.02, 6.09, 6.03, and 5.99. Estimate the
systematic and maximum random error. - ANSWERSystematic error: -0.08V
Maximum random error: -0.07V
Determine if the following errors are of random or systematic type.
A digital scale, that always shows 0.2 lb when no weight is applied -
ANSWERsystematic error
The vibration of the needle of an automobile speedometer - ANSWERrandom error
The consistent temperature difference between two sensors reading the air
temperature in the same room - ANSWERsystematic error
effect of temperature on the circuitry of an electronic measurement device -
ANSWERsystematic error
effect of parallax on the reading of a needle-type analog voltmeter -
ANSWERsystematic error
effect of using an incorrect value of emissivity on the readings of an infrared
thermometer - ANSWERsystematic error
variation in the makeup of a drug due to a malfunction of a mixer in a drug mixing
tank - ANSWERsystematic error
you need to measure a pressure, which has a value between 60kPA and 100 kPA.
Four pressure-measuring devices of comparable quality are available
which one would you choose? - ANSWERDevice D, range 50-150 kPA
