00:00So today I want to discuss what is prism constant and what is prism constant in Leica Builder 405
00:09This is with us for setting the prism name is Aldi Iger
00:22What is its name? Right now you are waiting.
00:30This is this this one true zero this is its name type parism is CP and triple one true
00:38Zero is the name of this prism.
00:40Now what is the prism constant, actually when a reflection is applied on it, of a shot, then that
00:51So, the observation of this place is given by this place, the passage from this place to this place is not counted in this.
01:00It happens, in this way
01:08She places observation here, she places observation here, she places observation here, due to this she finds her Paris Constant
01:18Is.
01:18So let's go to Lyca Builder, how to set the prism constant in Lyca Builder
01:28Its Izer will come, this button is also there, it comes directly from here, its Idiom setting is in Idiom setting
01:40If it is then it is red dot and red dot in
01:48It will be felt whether a weak signal comes or a strong signal comes and the remaining wood, iron or anything else will be there.
01:57It will be short due to the red dot and below this is trekking, the purpose of coming for trekking.
02:05is that once observed
02:16Keep reading, it's fine, as long as you don't escape. Okay, Prism, let's come to Prism. Prism.
02:24Now this is with us which I told you is a true prism, so if you have it like this
02:31There are other names like JP Many Many Rand, Aam P Aa.
02:39bess número 12 plus Gr 14 gird 4 user abhi user ke nathe phir aa gaya 자 constant ki jah

02:52Now if you put the name which is present in it in the same way
02:58Ko Chanstant
03:10to note
03:12Setting the total machine
03:21Any direction to tell life
03:23And then the same prism that Rap wants to use
03:28The distance of the shot is five meters, six meters, ten meters, etc.
03:34of distance.
03:36You'll get the distance. Or you'll get a lower reading, as the lower the reading.
03:45Come
03:45If it's one, write it here. If it's more, write it in minus here.
03:53This is the method of INSTAN'T of the parameter. The parameter constant is set to be the parameter of the Laika Builder 405.
04:03Constant's method was okay.
