Methods of measurement

1.Point to the measurement method of point

As shown in figure3. The range finder is placed on the ground to hang the needle points to the starting position, then the reading adjustment counter to zero, then start along the direction of the arrow straight forward mobile measurement turn a certain point. When to stop the advance of the vertical needle assigned to the marked position, then record the numerical counter, that is the actual measured value.

2.Methods of measurement on a certain point in the wall

As shown in figure4. The range finder is placed on the ground to wear rubber wheel on the initial measurement of the wall, and then the reading adjustment counter is zero, then start along the direction of the arrow straight forward mobile measurement turn a certain point. Stop and then hang needle specified ground marked for numerical end, then record the counter. Then the value of the counter and the last of the wheel radius (79.5mm) is the actual measured value.

3.Measurements of the walls

As shown in figure5. The range finder is placed on the ground to wear rubber wheel near the back wall, then the reading adjustment counter is zero, then start along the direction of the arrow straight ahead turn mobile measurement across the wall. When numerical record counter measuring wheel contact to the opposite wall after, then the value of the counter and the last wheel diameter (159mm) is the actual measured value.

The matters needing attention

1.The measuring wheel should be measured on a flat surface measurement, if will influence the accuracy of measurement in the bumpy road.

2. If there is no readings when measuring counter, and is accompanied by a rattling noise, as long as the press again counter to zero button, the counter reads zero can be restored to normal.

3.The strict implementation of national product three packs of provisions, if the normal damage in the normal use of the company is responsible for free repair and replacement.
