10. Set the altimeter test set back to sea level (0 ft')
11. Set the
BIAS
so that the altimeter reads 0 ft.
12. Complete the calibration by setting the altimeter test set to each altitude listed on the
calibration page (5000, 10000, 15000, etc.), and adjusting the corresponding entry until the
altimeter reads this altitude.
13. The accuracy of the scale factor adjustment can be verified by noting a small altitude error
(less than 200 feet) is observed with a zero correction at 30,000 feet.
14. Adjust the 30,000 foot correction until the altimeter reads 30,000 feet.
15. Exit the calibration page. Calibration is complete.
If necessary, the
BIAS
adjustment can be made without affecting the other corrections at any time.
