How to measure

1.Measuring method from wall to wall:

Put the range wheel on the ground and let the rear wheel lean against the back wall. Start moving in a straight line to the next wall. When the current wheel touches the front wall, record the measurement data on the display. The correct reading data must be added to the length of the wheel diameter.

2.Measuring from the wall to the next fixed point:

Place the range wheel on the ground and let the rear wheel lean against the back wall. Start moving in a straight line to the next point, and mark the end point on the bottom of the stop needle. Record the measured readings on the table. The correct reading must be made by adding the radius of the wheel.

3.Point-to-point measurement method:

Put the Measuring wheel at the starting point and start with the lowest point of the vertical needle. Start at the lowest point marked by the next vertical pin. Record the readings on the table below. This reading is the final measurement between two points.
