How to use the compass.
The compass must be placed horizontally and at a distance from magnetic objects to avoid misalignment.
1. >10 metres from barbed wire.
2. > 55 metres from high voltage lines.
3. >20 metres from cars or aircraft.
4. Distance from objects containing strong magnetism, such as various magnets and external magnetic speakers >10 metres.
5. Distance from objects containing weak magnetism, such as magnetic buttons > 0.5 m.
Cautions.
1. Use in a horizontal position to ensure maximum accuracy.
2. To avoid misalignment of the magnetic needle, keep a distance from wire mesh and objects containing magnetism.
3. Do not strike objects with the measuring tape as this will affect the accuracy of the measurement.
4. Keep the disc surface and lens clean and do not wipe with a dirty cloth or hands.
5. Turn off when not in use and do not place near ferromagnetic substances to avoid losing magnetism.
