Distance measuring wheel Fieldmann FDLM 1040 — 40 m range, ft/m units, 3 mm accuracy, Li‑Ion battery

Fieldmann FDLM 1040 is a compact distance measuring wheel designed for quick linear measurements up to 40 m. The device supports metric and imperial unit display (metres and feet), provides a stated accuracy of 3 mm and can measure from a minimum distance of 0.2 m. A built‑in lithium‑ion battery powers the unit, enabling repeated use on construction sites, in landscaping and for other short-range measuring tasks where portability and simple operation are required.

Advantages

The measuring wheel combines a lightweight, compact body with a 40 m measuring range and dual unit readout for flexible use in different working environments. Its 3 mm accuracy and 0.2 m minimum measurement capability make it suitable for short-distance layout and verification tasks. The integrated lithium‑ion battery eliminates the need for frequent battery replacement and supports continuous field work. The device is designed for straightforward handling and quick measurements without complex setup.

Suitable for

• Construction site layout and simple distance checks
• Landscaping and garden planning
• Surveying and measuring short stretches of road or paths
• Interior fit-out measurements and furniture positioning

Key specifications

• Maximum measuring range: 40 m
• Units: metres and feet
• Accuracy: 3 mm
• Minimum measurable distance: 0.2 m
• Power source: built‑in lithium‑ion battery
• Form factor: compact, hand‑held measuring wheel

How to use

Hold the device by the handle and place the wheel at the starting point of the measurement. Walk the wheel along the line to be measured at a steady pace until you reach the end point; the display will show the measured distance in the selected unit (metres or feet). For short measurements under 1 m, ensure the wheel makes consistent contact with the surface to maintain accuracy. Recharge the internal lithium‑ion battery using the supplied charger before extended use and follow the manufacturer's instructions for safe charging and storage.

Usage recommendations

For optimal results, use the measuring wheel on relatively flat, continuous surfaces and avoid excessive bouncing or abrupt turns during measurement. Select the appropriate unit (m or ft) before starting and verify calibration occasionally by measuring a known reference distance. Keep the device clean and dry, and recharge the battery when low to ensure reliable operation on site.
