One Is the digital electronic level accurate
It is quite troublesome to use a traditional level gauge, and there are still defects of inaccuracy when viewed with the naked eye. Therefore, a digital level gauge was invented, which can display readings through a liquid crystal urine screen, which is very convenient. However, the convenience of using a level gauge is secondary, and the key is to be accurate. Is the digital level gauge accurate?
In fact, the digital level is only displayed in a different way, and its principle is the same as that of a regular level. The accuracy of measurement is not affected, and the specific accuracy is related to the accuracy of the digital level.
However, it should be noted that, unlike ordinary level rulers, the measurement accuracy of digital level rulers is affected by temperature. Generally, measurements are more accurate within the range of 20-30 ° C, and high or low temperatures can affect its accuracy.
How to calibrate the digital display level
The traditional handheld level is usually calibrated using a standard device. With the development of technology, the invention of digital level makes the calibration of the level easier,
Just press the "calibration button" to introduce the calibration operation method of the digital level ruler:
1. Place the level ruler on a plane not exceeding 3 ° (which can be compared to the level) and wait for 10 seconds.
2. Press the calibration button once, and the display screen will display CAL1.
3. Turn the digital level gauge 180 °, wait for 10 seconds, and then press the calibration button. The display will display CAL2. After about 5 seconds, the LCD screen will display "Succ" and the buzzer will beep three times continuously, indicating successful calibration.
4. If after calibration, the LCD display screen displays three dashes - - - ", indicating that the horizontal ruler is not parallel to the horizontal plane during rotation and calibration is not successful, the calibration operation can be redone.
Reminder: When using the calibration key to calibrate the digital level, the 0 ° standard can only be reset on a plane less than 3 °. If the plane exceeds 3 °, the calibration key will not work.
