Question 3: What method do you use to ensure proper calibration of a light intensity meter in varying light conditions?

Which action should you take?

Choose only one option

By testing the meter in a dark room and assuming accuracy in other conditions

By using known reference light sources and adjusting the meter's response to match the reference

By measuring light only in one condition and assuming accuracy

By adjusting the meter until it provides the desired output

Question 4: What is the primary purpose of performing a load test on a battery?

Which action should you take?

Choose only one option

Verify the electrolyte level

Assess the battery's ability to deliver current over time under specified conditions

Measure voltage only

Measure the battery's physical size

Question 5: What method do you use to calibrate a temperature controller to ensure accurate heating and cooling cycles?

Which action should you take?

Choose only one option

By adjusting the controller's output without testing the system

By comparing the controller with a non-calibrated temperature sensor

By applying known temperature sources and adjusting the controller set points and feedback mechanisms

By testing the controller under load and ignoring the thermal lag

Question 6: How do you calibrate a tachometer to ensure it is providing accurate rotational speed readings?

Which action should you take?

Choose only one option

By assuming the tachometer is accurate based on manufacturer specifications

By comparing the tachometer readings with a digital multimeter

By testing the tachometer with varying rotational speeds without adjustment

By using a calibrated reference device, such as a laser tachometer, and adjusting the tachometer's output
