Q:

# How do you use a laser ruler?

A:

To use a laser ruler, place the laser ruler at one end of the distance to be measured, and point it towards the end point. An obstacle at the end point has to be present for the laser to hit. This process requires only a laser ruler and a distance to measure. A laser ruler or a laser tape measure is an alternative to regular tape measures and is highly accurate over long distances.

1. Place an obstacle at one end of the distance

Unlike conventional measuring tapes, laser rulers use laser beams that don't just come to a halt after travelling a certain distance. There has to be something to stop the laser beam from traveling any further than wanted. If there is no obstacle to stop the laser, then set one up at one end of the distance to be measured. When setting up an obstacle, make sure that it's accurately positioned so the laser beam can hit it.

2. Put the laser ruler at the other end

After making sure that there is an obstacle at one end of the length to be measured, place the laser ruler at the other end. Make sure to place the laser ruler at the correct position to get an accurate reading.

3. Point the laser at the obstacle

When both the obstacle and the laser ruler are in position, point the laser at the obstacle placed at the other end. Align the laser with the obstacle.

4. Calculate the distance

With the laser pointed at the object, press the button on the laser ruler, which now calculates the distance and displays it on its screen.
