Final answer:
When replacing chart paper in a course recorder, testing electrical gain to thermograph pens is not required. Instead, aligning the paper with the correct time, quadrant, and ship's heading ensures a correct trace.
Step-by-step explanation:
When replacing the chart paper in a course recorder to ensure a correct trace is recorded, it is not required to test the electrical gain to the thermograph pens. A course recorder is a navigational tool used to plot the heading of a ship, and its accuracy is mainly dependent on the correct alignment of the paper with the time and the correct heading marker, and ensuring the pen is set to the correct quadrant. Testing the electrical gain to the thermograph pens is generally associated with equipment that records temperature, such as a thermograph, rather than with a course recorder that tracks direction.
Thus, the correct steps when replacing the chart paper on a course recorder would be to:
- Adjust the chart paper to indicate the correct time.
- Set the zone pen on the correct quadrant.
- Line the course pen up on the exact heading of the ship.
