How to Find Horizontal Distance (HD) on Level Machine

Level instrument is mostly using in survey site . in this post How to Find Horizontal Distance (HD) on Level Machine will teach you with formulas that's way we brought for you very easy practical post for you read it step by step . After completing all practical you will be able to work on level machine for related post click level machine label or click on related  post.

TO FIND OUT Horizontal Distance HD on Level Machine

First of all open tripod and expand it on ground and then fix level on tripod plate with the help on plumbing fork
Now set the bubble with help of leveling screw. when bubble come to the center then leave leveling screw your instrument is ready for work
If you are using machine first time you must be check Machine Fault

 Select two point e.g. (A & B ) where you want to find horizontal distance ( H.D ) between two point .
Now keep staff rod on first point ( A ) and target staff rod and take reading on staff rod on upper hair and then keep the rod on second point (B) and take reading on rod with the help on lower hair.
Now you have two point dimension.

you can find Horizontal Distance HD on Level Machine in b/w these point ( A----B)

With the help of these formulas
Formula;.
   Upper hair -  Lower hair * 100  = H.D
OR
      A  - B *100 = H.D
Level machine can only find straight line distance.
It is only design for Leveling.

In simple language
Find H.D on Level machine
Set level machine  keep level machine on point “A” target staff rod take reading on upper hair note it .
Then  keep staff rod on point “B” take reading on lower hair
Also note it.
Now use these formula for finding horizontal distance.
      Upper hair - Lower hair * 100  = H.D
Like we have data.
A = 200
B = 150
                        200-150 * 100     =5000
