Applicable modes:
Using the compass
Note
• It may not measure correctly when you measure with this unit upside down.
• The bearing measurement value may be affected in locations with weak geomagnetism.
• It may not measure accurately if close to the following objects:
– Permanent magnets (metals in magnetic necklaces, etc.)/metallic objects (steel desks,
lockers, etc.)/high-voltage lines or overhead wires/household appliances (TVs, PCs, mobile
phones, speakers, etc.)
• It may not measure accurately in the following locations:
– Inside cars/trains/ships/airplanes/rooms (when the steel beams are magnetized)
8 bearings are measured based on the direction the lens
of the camera is pointing in.
•
The colored portion of the compass needle points north.
• When [GPS Setting] is set to [OFF], magnetic declination is
not corrected.
North
About the declination adjustment
Earth is a giant magnet with the South Pole at the Geographic North Pole and the North
Pole at the Geographic South Pole, and the magnetism the Earth has is called
“geomagnetism”. There is a difference between the angle of the “magnetic north” that a
magnetic compass points to and the geographical “true north” due to the effect of the
“geomagnetism”. The difference between these angles is called “declination”.
The compass in this unit points “true north”, when it corrects “magnetic declination”
based on the latitude and longitude acquired in the GPS positioning.
•
The size of the magnetic declination can change as you move to different locations, so we
recommend that you set [GPS Setting] to [ON] and perform positioning regularly to update
your latitude/longitude.
