Additional details
1. Wall-to-wall measurement
Place the measuring wheel on the ground with the rear wheel against the starting surface; roll the wheel straight until it reaches the end surface; record the dial reading and add the wheel diameter (2R) for the correct distance.
2. Wall-to-point measurement
Place the wheel on the ground with the rear wheel against the starting surface; roll until the positioning pin aligns with the endpoint; record the dial reading and add the wheel radius (R) for the correct distance.
3. Point-to-point measurement
Place the wheel on the ground with the positioning pin aligned to the start point; roll until the pin aligns with the endpoint; record the dial reading as the correct distance.
Do not disassemble the device unless you are a professional.
