Questions and Answers

1.

The adjustment at the blue arrow is used for:
- A.
  
  To adjust the "zero" of the indicator in case the gyro sensor is not exactly zero
- B.
  
  To adjust the "zero" of the indicator, when the indicator is turned off
- C.
  
  To adjust the "zero" to the processor of the BasicTriplePilot
- D.
  
  To adjust the "test" of the Rate of Turn signal
Correct Answer
B. To adjust the "zero" of the indicator, when the indicator is turned off

Explanation
The adjustment at the blue arrow is used to adjust the "zero" of the indicator when the indicator is turned off. This means that when the indicator is not in use, the adjustment can be made to ensure that the indicator is calibrated correctly and shows zero when it is supposed to. This adjustment is necessary because the gyro sensor may not always be exactly zero, so the adjustment allows for fine-tuning and accuracy when the indicator is turned off.

In case of a "ROT" MFM Rate of Turn, what type of display is used?
- A.
  
  Repeater display
- B.
  
  Indicator display
Correct Answer
B. Indicator display

Explanation
In the case of a "ROT" MFM Rate of Turn, an indicator display is used. This type of display provides a visual representation of the rate of turn, allowing the user to easily monitor and interpret the information. It typically includes a dial or gauge with markings indicating the rate of turn in degrees per minute or degrees per second. The indicator display is designed to be clear and intuitive, enabling quick and accurate readings of the rate of turn.

Select all correct answers:
- A.
  
  The "gain" and "speed" potentiometers are not allowed to adjust without special test-equipment
- B.
  
  The "test" potentiometer should be adjusted on board after installing a gyrosensor
- C.
  
  The "speed" potentiometer is for the maximum curve of the Riverpilot
Correct Answer
A. The "gain" and "speed" potentiometers are not allowed to adjust without special test-equipment

Explanation
The "gain" and "speed" potentiometers are not allowed to adjust without special test-equipment because these adjustments can significantly affect the performance and stability of the gyrosensor. Without proper test equipment, it is difficult to accurately measure and calibrate these potentiometers, which can lead to incorrect readings and unreliable operation of the gyrosensor. Therefore, it is important to restrict the adjustment of these potentiometers to ensure the proper functioning of the gyrosensor.

Select all correct answers:
- A.
  
  The "isozero" potentiometer is used for zero adjustment for the Riverpilot
- B.
  
  The "zero" adjustment is used for adjusting the "zero" indication on the radar
- C.
  
  On board ONLY adjust potentiometers "zero" and "isozero".
Correct Answer(s)
A. The "isozero" potentiometer is used for zero adjustment for the Riverpilot
C. On board ONLY adjust potentiometers "zero" and "isozero".

Explanation
The correct answer is that on board, only the potentiometers "zero" and "isozero" should be adjusted. The "isozero" potentiometer is specifically used for zero adjustment for the Riverpilot. This suggests that these potentiometers play a crucial role in calibrating and adjusting certain components or indicators on the onboard equipment.

What voltage do you measure between "5" and "7" on the gyro sensor when the ship does not move at all?
- A.
  
  Less then 100 millivolts
- B.
  
  Less then 20 millivolts
- C.
  
  Less then 10 millivolts
- D.
  
  More then 10 millivolts
Correct Answer
C. Less then 10 millivolts

Explanation
When the ship does not move at all, the gyro sensor should not detect any significant change in voltage. Therefore, the voltage measured between "5" and "7" on the gyro sensor should be very low. The answer "Less than 10 millivolts" suggests that the voltage measured is expected to be less than 10 millivolts, which aligns with the explanation provided.
