The statement is stating that measurement converters convert signals from one form to another, which is true. Measurement converters are devices or instruments that are used to convert signals from one form to another, such as converting analog signals to digital signals or vice versa. These converters are commonly used in various industries and applications where signal conversion is required for proper measurement and analysis. Therefore, the given answer "Točno" (True) is correct.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The correct answer is "mjerno područje". This term refers to the range of values that can be measured using a particular instrument or device. It encompasses the minimum and maximum values that the measurement can detect or quantify.

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.

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.

The given answer includes the correct characteristics of a measuring instrument. The output impedance refers to the impedance of the instrument's output circuit, which affects the accuracy of the measurement. The type of measuring signal refers to whether the signal is analog or digital, which determines the format of the output. The range of the measuring signal refers to the range within which the instrument can accurately measure. Therefore, the answer includes the relevant properties of a measuring instrument.
