Over what distance are you measuring?
Certainly check your prism constant but there are many other possibilities.
Hope this helps
Hi David,
I used in the fine mode / put the Temperature/Pressure / the baseline is a short distance in this case is 10mts.
The prism is in a tripod with tribrach with adapter and the total station is in a collimator( Photo of the collimator).
I believe that problem is in the instrument, needs to be calibrated.
In the country that I work, I think there is no Technical Assistance to Leica.
I have counseled the client to go to a Leica representative.
Thank you all!
I'm going back a while now but when we used to use the main Leica prisms for other instruments we used to set the prism constant at 34.4 for zero error.

Hi Paulo, You said you have a manual,then look on page 25, But here is what to do press menu for more than 2 sec. You will see Config, Menu, on #1 you will see ppm/mm, there is where you can set your prism
constant, this is in detail on page 91 ppm / page 92 prism mm., Back to config.Menu # 2 Is CALIB instrument error,this is where to check and correct the Gun 1 is V-index and 2 is H Collim, In this Config. Menu ,you will find all of the settings1. ppm /mm 2. Calib 3.Contrast 4.rec data 5. units 6.time /date 7.on /off.
You also have a Main Menu with a tree under Menu and Prog menu with a tree.
hope this helps.
One possibility is a prism/instrument constant issue.
Leica instruments expect a prism with 34mm constant, and many prisms are 30mm; which would result in the 4mm that you refer to.
Something to look into.
Also, ensure that whatever value you are treating as the correct value is actually correct. If something was established badly there may be no problem with your measurement at all.
Hi Timothy,
The CP is correct.
I have the same error (4mm) when use laser.
For example. I did a baseline with 10mts, with diferente total Station everything is ok with and without prism. With this TCR805 I have 4mm.
Resume the equipment have 4mm error, I just want know if the operator can correct this error.
I do not know very well Leica equipments.I already read the operator manual and did not see any function to correct EDM.
