Note the use of a handheld laser rangefinder.
1. Pay attention to the positive and negative poles when installing the battery, and only use alkaline batteries.
2. When measuring, do not point the laser directly at the sun, eyes or irradiate the eyes through reflective surfaces (such as mirror reflection).
3. Be careful when using it, and avoid placing it in a place that is too humid, high temperature or exposed to direct sunlight.
4. The sunlight is too strong, the ambient temperature fluctuates too much, the reflection effect of the reflective surface is weak, and the error of the measurement result is large when the battery is low. In this case, it is better to use it with the target reflector.
Maintenance of handheld laser range finders.
1. It is forbidden to store the instrument in a high temperature and high humidity environment for a long time. When the instrument will not be used for a long time, please take out the battery, put the instrument in the random instrument case, and store it in a cool and dry place.
Please keep the surface of the instrument clean. Use a damp soft cloth to wipe the dust on the surface of the instrument. Do not use aggressive lotion to clean the instrument. You can wipe the laser window and focusing mirror according to the method of wiping the surface of an optical instrument.
Measurement.
1 single distance measurement.
Press the READ key, turn on the laser beam, aim the instrument at the target to be measured, and then press the READ key. The measured distance data will be immediately displayed on the display in the specified unit.
2 Measure Min/Max.
This function can measure the minimum and maximum distances starting from a fixed point, and measure the separation distance.
Press and hold the READ key until a beep is heard, then the instrument enters the continuous measurement mode, and then sweeps the laser slowly in front of and behind the target.
Press the READ button again to terminate the continuous measurement mode, and the measured maximum or minimum distance will be displayed in the main display area on the screen.
