Example of adjusting the altitude manually
(measuring the height from the ground to the roof of a building)
1Set [ON] in [Adjust] in [Altimeter] on the ground A, and then
set the altimeter to 0 m (0 feet).
2Move from the ground A to the roof B.
3Check the altitude measured on the roof B.

(relative altitude)
When [Adjust] is set to [GPS], the altitude prior to and after record ing can vary according to the
timing at which GPS data is received.
Adjustment is not possible when the measured value exceeds the display range. It will display [----].
With the displaying of the relative altitude, it may display with negative numbers even if it is higher
than sea level depending on the value adjusted with [Adjust] in [Altimeter].
After adjustment, errors of a few metres may still occur. For information on preserving the adjusted
accuracy, read About the measured altitude and atmospheric pressure (P143).
