How to use the compass:
The compass must be placed horizontally and at a certain distance from magnetic objects to avoid misalignment:
1. > 10 m from barbed wire;
2. > 55 metres from high voltage lines;
3. > 20 metres from cars or aircraft;
4, from objects containing strong magnetism, such as various magnets, external magnetic speakers > 10 meters;
5. > 0.5 m from objects with weak magnetism such as magnetic buttons.
Caution:
1. Use in a horizontal position to ensure maximum accuracy;
2. To avoid misalignment of the magnetic needle, please keep a certain distance from wire mesh and objects containing magnetism;
3. Do not hit the object with the measuring tape as this may affect the accuracy of the measurement;
4. Keep the disc surface and lens clean, do not use a dirty cloth or hand to wipe;
