Instrument calibration is the value obtained by testing the measuring instrument or measuring system to determine the result of the value shown by the instrument. It belongs to a set of operations.
Everyone knows that the rangefinder is a kind of measuring instrument, which is a test of data. In the daily operation of the rangefinder, it is operated artificially. After a certain period of use, the instrument will be affected by surrounding factors such as dust. , Air, movement, humidity, etc., there will be more or less errors. Just like people, in daily exercise and daily work, there will be more or less minor problems. Sometimes we don’t know if the measuring tools will have these issues or not. What's wrong, so calibrate before each use to ensure the data, and the results of the inspection will be reflected in the inspection report in detail. Therefore, the same is true for instrument calibration. When using the instrument, you want to know whether the instrument is accurate when measuring the product. Therefore, you must perform instrument calibration on a regular basis so that the measured data will be relatively accurate.
The instrument calibration is the doctor of the rangefinder who conducts regular inspections of the instrument to ensure that the data error is small.
The following is the calibration method :
The first step:
In the shutdown state, press and hold the "Power on key" + "- key" at the same time, let go after hearing the beep of the buzzer, and "CAL ANGLE" appears on the page, indicating that you have entered the angle calibration mode.
The second step:
Place the machine on a horizontal platform.
Press the "Power button" and once after hearing the sound, the screen displays "3-1" And then machine will automatically calibrate the horizontal plane. While the machine calibration success, "3-2" is displayed, as shown in the figure.
The third step:
Place the machine vertically, press the "start button" and let go after hearing the sound.The machine will automatically calibrate the positive vertical. After success, "3-3" is displayed, as shown in the figure:
The fourth step:
Put the machine in the background, "press the start button" and let go after hearing the sound,
The machine will automatically bounce parallel. After success, it will automatically rebound and recover.
If you have any question for calibration, please do not hesitate to contact us,we will help you to slove the problems, the laser distance meter can be record 30 group data, which can reach the measuring tasks as you need.
