Using a laser rangefinder: how to do it?

At the hands of a professional, the laser rangefinder is a powerful tool that allows to measure with precision. Entry-level models are also available on the market for homebuyers. However, special precautions must be taken when using the laser range finder.

The use of a laser rangefinder


The first thing to know is that a laser rangefinder should only be used to measure a distance and calculate a surface and volume. However, it is forbidden to use this device in cases where the limits of the measuring range specified by the manufacturer are exceeded, compromise or deactivation of the safety systems integrated in the appliance or Removal of the risk or explanation labels affixed to the device.

It is also not recommended to use the laser rangefinder when there is a change or conversion of the original use of the device, use of accessories not supplied with the laser rangefinder, use on scaffolding or Scales without appropriate safety measures. In addition, use of the device should be avoided if it is measured in the vicinity of machines in service or parts of unprotected machine installations or if the direction of measurement is in direct sunlight.

Finally, do not use a laser range finder outside or on the road, near building sites and without adequate precautions if the device has been modified or adjusted for other purposes. Apart from these restrictions, care must be taken to strictly observe the different stages of use. The first is to position the laser rangefinder on the ground from its flat base in order to stabilize it.

Then, it is necessary to point the beam towards the wall or the opposite target, before adjusting the height approximately. The level indicates the precise location of the bulkhead.

The next step is to adjust everything to find the desired level. Next, position the user’s level as close as possible to the area of ​​intervention. It is imperative not to distort the measure.

Finally, the user can draw with a pencil so as not to have to renew the adjustment when the laser rangefinder is moving. Once this first grip is mastered, the use of the laser rangefinder should be done without problems.

Safety conditions and factors to consider when taking measurements

The use of a laser rangefinder is difficult enough for a beginner and to achieve this, one must consider certain factors. We must first favor flat, smooth and hard targets. The use of a piece of cardboard or similar material is necessary if the size of the target is to be increased.

In addition, you should periodically check the power meter to see if the meter needs to be recharged or if a battery change is required.

Good to know, the rangefinder is not able to measure through glass, liquid or polystyrene foam. Should the instrument give false measurements or inaccurate values, the source of the problem could be the unloading of the power source. But a fault of this type can also be caused by the fact that the measured distance exceeds the indicated range and the presence of irregularly shaped objects in the vicinity of the target or in the zone of intervention.

Apart from this, there are safety measures to be observed when using a laser rangefinder. It is therefore mandatory to read and understand the instruction manual before taking it into hand. As mentioned above, the performance of the laser device should in no way be changed. And with regard to the latter, it is strictly forbidden to look at the beam. This can cause flash blindness.

It is strictly forbidden to leave this appliance within reach of children: it is not a toy. A laser range finder should not be used on surfaces such as sheet metal panels or simply reflective or shiny surfaces.

Avoid using the device near flammable gases.
