In view of the difference of the instrument bai, the answer to this question should be divided into options, let's give you a process below!
1. It depends on whether it is an electronic level or an optical level. Directly press the touch key of the electronic level against the level ruler, and there will be a reading on the display, which can be read directly; the optical level depends on the level of accuracy——
2. For optical level S1 and above (such as N3 level), you need to read three integers on the level ruler (reading to a whole centimeter), and then read the other three readings on the level (mm to 0.01 mm). If it is an S3 level -
3. Look again at what kind of level it is. The operation steps of automatic and non-automatic Anping are slightly different:
If it is an S3 automatic leveling level, you only need to level the level and read directly to the level ruler.
If it is a non-automatic level, then the level is adjusted, and the aiming level rod is adjusted to match the bubble before reading.
4. How to read the level ruler:
(1) Erect image level (level model S3 followed by "E"), read from the bottom to the top of the ruler when reading; inverted image level, read from the top to the bottom of the ruler when reading.
(2) When reading, first look at the "point" of the big "E" on the level ruler, which is the starting point of each 10 cm. Then read the ruler like a ruler, and estimate it to millimeters.
