Measuring Wheel-Digital

Distance measuring wheel is also known as mechanical rangefinder car, digital display measuring wheel，and measure wheel. wheeled rangefinder is designed for outdoor distance measurement designed and manufactured for a variety of ground conditions, including hills, meadows, rugged construction sites and so on. lightweight design allows field workers to carry very convenient , greatly reducing the work fatigue. measurement range of the product 0-9999.9 m , reached domestic leading level. large digital display system makes clear clear and accurate readings , and to install a night display lighting system to facilitate in poor light conditions of use ; folding steel tubular handle bars greatly reduced the volume of storage and handling ; using lightweight and flexible, durable ; therefore been widely used in professional surveying and mapping activities, roadworks , pipeline laying , cable engineering, construction work measurement and evaluation , garden landscape and golf course construction survey , traffic accidents from the position measurement , and measurement of farmland construction management , etc. , and its time-saving advantages are increasingly easy the more industry sectors are discovered and exploited .

Use the information
1. According to the instructions prior to measurement, the counter to zero.Put the wheel flat counter displays 0000.0 meters.
2. If the measure in a straight line, go straight to ensure the accuracy of measurement.
3. Do not measure the jagged surface, will reduce the accuracy of measurement.
4. Don't measure in the rain for a long time.
5. Don't in the environment of high temperature measurement, do not store in high temperature place.
6. Do not use the instrument as children toys, avoid unnecessary damage.
