What are the common types of laser rangefinders and how to use them
1. Handheld laser range finder
The measurement distance is generally within 200 meters, and the accuracy is about 2mm. This is the most widely used laser rangefinder at present. Functionally, in addition to measuring the distance, it can also generally calculate the volume of the measured object.
2. Cloud service laser range finder
The measurement data on the laser range finder is transmitted to mobile terminals such as mobile phones and tablet computers in real time through Bluetooth; the data can be transmitted to the cloud server through wifi networking, and the measurement data can be shared in real time with remote construction partners.
3. Telescopic laser range finder
The measurement distance is relatively long, the general measurement range is about 3.5 meters to 2000 meters, and there are also ranging telescopes with a maximum range of about 10 kilometers. Due to the collimation requirements of the ranging telescope, the blind area is below 3.5 meters, and the laser is greater than 2000 meters. Telescopes generally use YAG lasers with a wavelength of 1.064 microns. In order to achieve a larger measurement range, the laser power is relatively high. Users are advised to pay attention to laser protection. The main application range is outdoor medium and long distance measurement.
In addition, it can be divided into one-dimensional laser range finder: used for distance measurement and positioning; two-dimensional laser range finder: used for contour measurement, positioning, area monitoring and other fields; three-dimensional laser range finder: used for 3D contour measurement, 3D space positioning and other fields.
Product features of PD-S laser range finder: Maximum distance: 60 meters, accuracy: ±1.5mm, continuous measurement, the smallest range finder so far.
Instructions
1. First of all, install the battery on the laser rangefinder. If it is charged directly, it must be fully charged before use.
2. Then each laser meter will have a power switch.
the
3. Through the eyepiece, you can see that the rangefinder is in standby mode, and you must select a good unit before measuring again.
4. Long press the mode button to directly select the desired unit.
5. Aim at the measured object through the internal LCD display in the rangefinder eyepiece.
6. After confirming the aim, press the launch button lightly.
7. If the measured object is not very clear, adjust the clarity of the measured object by =/-2 diopter adjuster.
8. Finally, adjust the distance by forward or reverse.
