Questions & Answers About Direction Readings
Question: What causes incorrect direction readings?
Answer:
• Incorrect bidirectional calibration. Perform bidirectional calibration.
Remember that bidirectional calibration is required whenever batteries
are replaced.
• Nearby source of strong magnetism, such as a household appliance, a
large steel bridge, a steel beam, overhead wires, etc., or an attempt to
perform direction measurement on a train, boat, etc. Move away from
large metal objects and try again. Note that digital compass operation
cannot be performed inside a train, boat, etc.
Question:What causes different direction readings to produce
different results at the same location?
Answer: Magnetism generated by nearby high-tension wires are
interfering with detection of terrestrial magnetism. Move away
from the high-tension wires and try again.
Question:What does it mean when
--- appears in place of a
direction value?
Answer: This is the abnormal magnetic field indicator. It means that strong
magnetism is being generated nearby. Move away from the
source of strong magnetism and try again.

Question:Why am I having problems taking direction readings indoors?
Answer: A TV, personal computer, speakers, or some other object is
interfering with terrestrial magnetism readings. Move away from
the object causing the interference or take the direction reading
outdoors. Indoor taking direction readings are particularly difficult
inside ferro-concrete structures. Remember that you will not be
able to take direction readings inside of trains, airplanes, etc.
Question:What do the numbers on the watch mean?
Answer: The face of this watch is marked with
values that increase in a counterclockwise
direction. These values represent degrees.
When you take a direction reading, you can
use these values to find out how many degrees
the 12 o’clock position of this watch differs from
magnetic north.
For example, when the Magnetic North pointer
is pointing at “90” on the watch’s face, it means
that the 12 o’clock position is 90 degrees from
magnetic north (which means that 12 o’clock
is pointing due east).
