Tips for using the latest fourth-class level measurement record sheet
The latest fourth-class level measurement record sheetPreparation of:
1. Installation level
Open the tripod and make it at a moderate height. Visually make the head of the tripod roughly horizontal. Check whether the legs of the tripod are firmly placed and whether the telescopic screw of the tripod is tightened. Then open the instrument box and take out the level. Place it on the tripod head and secure the instrument firmly with the connecting screw. Attached to tripod head.
2. Rough leveling
Rough leveling is to use the bubble of the circular level to center the instrument so that the vertical axis of the instrument is roughly vertical, so that the collimation axis is roughly horizontal. During the leveling process, the bubble moves in the same direction as the left thumb.
3. Aim at the leveling rod
First, align the eyepiece, that is, point the telescope against a bright background, and turn the eyepiece alignment spiral to make the crosshairs clear.
4. Precision leveling and reading
Look at the level bubble with your eyes through the matching bubble observation window on the left side of the eyepiece. Turn the slightly tilted screw with your right hand to make the images at both ends of the bubble match, which means that the sighting axis of the level is accurately level.
1: How to sum text
In some relatively non-standard tables, there will be a problem of mixing text and numbers, which makes summation difficult.
Enter the formula in cell C12: =SUM(--SUBSTITUTE(C2:C11,"元",""))
Press the key combination to complete.
2: Sum of multiple worksheets
For example, some tables have performance statistics for several months, and Zhang Cheng’s position in each worksheet is the same. Find Zhang Cheng’s commission statistics from a certain month to a certain month.
Enter the formula in cell F5: =SUM('January:April'!C2), and press Enter to complete the filling.
Note: The above reference is supported in Excel, but it seems not supported in WPS. And please note that the structure or fixed position of the numbers in each table is the same before you can use this formula.
3: Multi-region joint calculation
In some worksheets, we do not need to sum continuous areas, but may be summing several discontinuous areas.
For example, there is a table that calculates the totals from January to February, March and May to June.
Enter the formula in cell H2, press the Enter key to complete and fill downwards.
=SUM(B2:C2,E2,G2)Recommended by the editor of Huajun Software Park
