How to use the laser level meter
One: First turn on the switch, (the switch is on the side) whether the laser level is three-wire or five-wire. There should be an automatic correction system on the level (there is a water drop correction on it, and the water drop is in the circle.) If it is not level, it will automatically make a sound, and there will be no sound after it is level.
Two: When measuring, make the working surface of the spirit level close to the surface to be measured, and take a reading after the bubbles are completely still.
Three: The division value of the spirit level is the inclination value based on one meter. If it is necessary to measure the actual inclination with a length of L, it can be calculated by the following formula:
Actual inclination value = division value * L * deviation grid number
Four: In order to avoid the measurement error caused by the inaccurate zero position of the level meter, the zero position of the level meter must be calibrated or adjusted before use.
