Given below are the answers to Infosys Fresher Aptitude 2020 Sample Question Paper Pseudocode. Comment below if you have any doubts. The full video is below for you to watch.
---You
decide to use the Endpoints method of linearization to linearize a Type
K thermocouple curve between 1000°C and 1050°. A screen shot of the
data points from the www.NIST.gov web site is shown below. What do you
calculate for the slope of the line using the Endpoints Method in
millivolts per °C? (Type in a 4-decimal number.)
0.039
---You decide to use the End Points method of linearization to linearize a Type K thermocouple curve between 1000°C and 1050°. A screen shot of the data points from the www.NIST.gov web site is shown below. How far off away from the actual voltage (in positive millivolts) is your End-points line at 1025°C, the mid-point of the curve between 1000°C and 1050°C? (Type in a 4-decimal number, which represents the absolute value of the error)
0.0035
---You decide to use the method of temperature compensation on a pressure sensor featured in our video on Temperature Compensation. You are compensating the sensor solely between the nominal calibration temperature of 25°C and the highest operating temperature. Other information is given in the table below. Given this information, what is the Sensitivity at Maximum Temperature S(Tmax) in volts/psi?
(Type in a 4-decimal number).
Hint: Make sure to carefully review the formulae in your video first. After that, it should be straightforward to do this calculation.

---You decide to use the method of temperature compensation on a pressure sensor featured in our video on Temperature Compensation. You are compensating the sensor solely between the nominal calibration temperature of 25°C and the highest operating temperature. Other information is given in the table below. Given this information, what is the Temperature Coefficient of Span (TCS)
(Type in the answer as the 3-decimal multiplier for 1E-05. (Example: type -3.497 to mean -3.497E-05)
Hint: Make sure to carefully review the formulae in your video first. After that, it should be straightforward to do this calculation.

----You decide to use the method of temperature compensation on a pressure sensor featured in our video on Temperature Compensation. You are compensating the sensor solely between the nominal calibration temperature of 25°C and the highest operating temperature. Other information is given in the table below. Given this information, what is the adjusted pressure in psi?(Type in a 1-decimal number).
Hint: Make sure to carefully review the formulae in your video first. After that, it should be straightforward to do this calculation.
Note that you should not get exactly 100 psi, as the point of this exercise is to show that your reading will never be perfectly accurate, even using linear temperature compensation.
Note: Table below is the same one, as per prior two questions
100.6
---Which of the following statements about a calibration standard are true?
The standard must have a known accuracy that is at least four times better than the sensor
---When does an ISO 10725 accredited laboratory issue a calibration certificate?
Each time the lab checks the calibration of a piece of customer equipment
---A 24 bit ADC has an input full scale (VFS) of 5 volts. What voltage in micro-volts is the LSB (least significant bit)? (Type in a 3-decimal number)
0.298
---A temperature calibration system equipped with a temperature bath has the accuracy values shown in the table below. What is the expanded uncertainty of the calibration process at a calibration process temperature of 800°C using a uniform (i.e. rectangular) probability distribution?
0.8101
