|
Automatic negative feedback is employed for regulating (controlling) systems?
(Yes - No) |
Yes
|
|
An advantage of using negative feedback is that it will make the system tolerant to sensor inaccuracy?
(Yes - No) |
No
|
|

Measurements from system A produce the following values (4.04 ; 4.05; 4.07, 4.03) and measurements from system B produce the following values (4.001 ; 4.002; 4.001, 4.001). Can you state anything concerning their accuracy?
(Yes - No) |
No
|
|
With a measurement system A, an operator 1 obtains the following measurements (1.01; 1.02; 1.01; 1.01) and, a week later, another operator 2 obtains the following measurements (0.71; 0.70, 0.71; 0.70). Would you say that system’s reproducibility is poorer than its repeatability?
(Yes - No) |
Yes
|
|
For the following transfer function for a sensor (S=a+bs), where s is the stimulus value and S is the output value, does a represent the sensitivity?
(Yes - No) |
No
|
|
In case of a linear transfer function, zero drift has an impact on sensitivity?
(Yes - No) |
No
|
|
In case of a linear transfer function, zero drift can be compensated with a single point calibration?
(Yes - No) |
Yes
|
|
Hysteresis negative impact on accuracy can be prevented by ensuring that stimuli are slow?
(Yes - No) |
No
|
|
If saturation is reached in a measurement system, does this imply a decrease in sensitivity?
(Yes - No) |
Yes
|
|
Measurements from system A produce the following values (4.04 ; 4.05; 4.07, 4.03) and measurements from system B produce the following values (4.001 ; 4.002; 4.001, 4.001). Can you state anything concerning their resolution?
(Yes - No) |
Yes
|
|
Measurements from a system produce the following values (4.001; 4.002; 4.001, 4.001). Which is the resolution uncertainty assuming that the quantification mechanism of the system rounds to the closest available value?
(± 0.001 - ± 0.0005) |
± 0.0005
|
|
Is zero drift a source of systematic errors?
(Yes - No) |
Yes
|
|
Random errors can be eliminated by calibration?
(Yes - No) |
No
|
|
Since noise is a source of random errors, does it make sense to average output values from a measurement system in order to obtain a more precise measurement?
(Yes - No) |
Yes
|
|
A linear transfer function can be calibrated just with two measurement standards?
(Yes - No) |
Yes
|
|
Warm-up time is the time between applying electric power to the system and the moment when the system can operate within its specified accuracy
(Yes - No) |
Yes
|
|
