    • Pripremu uređaja za rad

    • Baždarenje i kalibrirarnje

    • Uređaje specijalne namjene

    • To se uopće ne radi

    Correct Answer
    A. Baždarenje i kalibrirarnje
    Explanation
    The correct answer is "baždarenje i kalibriranje." This means that the working conditions in which measurement standards are experimentally tested are used for calibrating and adjusting the devices.

    Mjerni _____________________  pretvaraju promatranu fizikalnu veličinu u drugi oblik (drugu fizikalnu veličinu) prikladan za daljnju obradu

    Correct Answer
    pretvornici
    Explanation
    The correct answer is "pretvornici". In the given statement, it is mentioned that "Mjerni pretvornici" convert the observed physical quantity into another form (another physical quantity) suitable for further processing. This implies that "pretvornici" refers to the devices or instruments that perform the conversion of physical quantities.

    Graf idealne statičke karakteristike je ___________

    Correct Answer
    pravac
    Explanation
    The correct answer is "pravac." This is because the term "graf idealne statičke karakteristike" translates to "graph of the ideal static characteristic." In this context, a "pravac" refers to a straight line or a direction. Therefore, the graph of the ideal static characteristic is a straight line.

    Elementi  regulacijskog kruga koji reagiraju na fizikalnu veličinu i mjere je nazivaju se 

    • Mjerni pretvornik

    • Mjerno osjetilo

    • Regulator

    • Izvršni član

    Correct Answer
    A. Mjerno osjetilo
    Explanation
    The correct answer is "mjerno osjetilo". In a control loop, the elements that react to a physical quantity and measure it are called "mjerno osjetilo" or "sensors". These sensors are responsible for converting the physical quantity into an electrical signal that can be used by the rest of the control system.

    ___________________ je razlika vrijednosti veličina na gornjoj i donjoj granici mjernog područja

    Correct Answer
    Mjerni opseg
    Explanation
    The given statement defines the term "mjerni opseg" in Croatian, which translates to "measurement range" in English. It refers to the difference in values between the upper and lower limits of a measurement scale. The measurement range helps determine the span or extent of values that can be measured accurately using a particular instrument or system.

  • 7. 

    Radni uvjeti mjernih slogova (20±5°C; 60±20%; 101,325±2,66 kPa) su uvjeti pod kojima mjerni uređaji jedino mogu raditi. U svim ostalim uvjetima oni ne rade.

    • Točno

    • Netočno

    Correct Answer
    A. Netočno
    Explanation
    The correct answer is "Netočno" which means "False" in English. The statement in the question states that the given conditions (20±5°C; 60±20%; 101,325±2,66 kPa) are the only conditions under which measuring devices can work. However, this statement is not true. Measuring devices can work under various conditions, not just the ones mentioned.

    Stvarna statička karakteristika se određuje

    • Prilikom uključivanja u rad u pogonu

    • Nakon ugradnje u regulacijski krug

    • Eksperimentom u radnim uvjetima tijekom kalibriranja

    • To nam zapravo uopće ne treba

    Correct Answer
    A. Eksperimentom u radnim uvjetima tijekom kalibriranja
    Explanation
    The correct answer is "eksperimentom u radnim uvjetima tijekom kalibriranja" because the actual static characteristic of a device is determined by conducting experiments in real operating conditions during the calibration process. This involves testing the device under various conditions and measuring its response to accurately determine its static characteristic. This information is crucial for proper functioning and accurate regulation of the device in a control system.

    Blizinu stvarne karatkteristike idealnoj linearnoj karakteristici (pravcu) pokazuje _____________

    Correct Answer
    linearnost
    Explanation
    The correct answer is "linearnost." This is because the question is asking for the term that best represents the close resemblance of the actual characteristics to the ideal linear characteristics (straight line). "Linearnost" is the Croatian word for "linearity," which describes the property of a system or characteristic that follows a straight line relationship.

    Ovisnost izlazne veličine o ulaznoj bez vremenske ovisnosti prikazuje

    • Dinamička karakteristika

    • Prijenosna karakteristika

    • Frekvencijska karakteristika

    • Statička karakteristika

    Correct Answer
    A. Statička karakteristika
    Explanation
    The correct answer is "statička karakteristika". This is because the question is asking about the dependence of the output variable on the input variable without any time dependence. In other words, it is referring to a situation where the output variable is solely determined by the input variable at a specific point in time, without any consideration of changes over time. This is characteristic of a static system or static relationship between the input and output variables.

    The given answer is correct because the input characteristics of a measuring instrument include the measured quantity, the measuring range, and the measurement range. The measured quantity refers to the physical quantity being measured, such as temperature or pressure. The measuring range is the range of values that can be accurately measured by the instrument. The measurement range refers to the range of values that can be displayed or recorded by the instrument. These input characteristics are essential in determining the accuracy and reliability of the measurement.

    A. Točnost i osjetljivost
    A. Inteligentni integrirani mjerni uređaji
    A. Daljinski prijenos podataka i memoriranje
    Explanation
    The reasons for converting non-electrical quantities into electrical quantities in the process of automatic regulation are: the information devices used are electronic, which allows for easier processing and manipulation of data; electrical measurements provide higher accuracy and sensitivity compared to non-electrical measurements; intelligent integrated measurement devices can perform complex calculations and analysis to optimize the regulation process; and remote data transmission and storage enable efficient monitoring and control of the regulation system.

    Mjerna osjetila imaju sljedeće karakteristike

    • Posredno ili neposredno u dodiru s materijom

    • Troši energiju mjerene veličine

    • Prima osnovni signal mjerene veličine i isti daje na izlazu

    • Vrši pretvorbu energije

    Correct Answer(s)
    A. Posredno ili neposredno u dodiru s materijom
    A. Troši energiju mjerene veličine
    A. Prima osnovni signal mjerene veličine i isti daje na izlazu
    Explanation
    The answer correctly states the characteristics of measuring sensors. Measuring sensors are either indirectly or directly in contact with the material being measured. They consume energy from the measured quantity, receive the basic signal of the measured quantity, and provide the same signal at the output. Additionally, measuring sensors also perform energy conversion.
