How to use the measuring device.

When you roll between two points on the map, the distance measuring pointer rotates accordingly. Record this value according to the corresponding scale, and then multiply it by the scale factor to get the actual distance between the two points,

which is much more accurate than the straight-line distance measured with a ruler; the map distance meter can measure mileage distance conveniently and quickly, and is specially used to measure the actual distance of curved routes on the map.

Precautions.

1. Use horizontally to for ensure the highest possible accuracy.

2. To avoid misalignment of the magnet, keep a certain distance from the screen and objects when using it.

3. Do not hit the object with the tape measure, as this may affect the measurement accuracy;

4. Keep the for surface of the disc and lens clean, and do not wipe it with a dirty cloth or hand;

5. It should be turned off when not in use, and do not place it near ferromagnetic materials to avoid losing magnetism.
