Thanks for your reply Ladislav. I know that but the automatic declination is calculated for the first januray of the year which is enter, not for the exact date. It's not a probleme for the accuracy of the survey ? Martin K. Le 2 mars 2018 17:05, "Ladislav Blažek" <ladislav@lblazek.cz> a écrit :
Hi,
declination should be calculated automatically based on the survey date. Declination parameter is for manual correction.

Quick question concerning the magnetic declination.
How you indicate it?
Just by entering the date or with the command <declination>?
Because when I just specify the date, the declination which is calculate is for the first January, even if I specify another month in the centreline (e.g. 28.08.2017). Consequently, centreline is slightly offset that if I enter the real declination for the date.
I don’t know if this shift is important for survey accuracy or if I can ignore it ?
Thanks and sorry for all my questions.
Martin K.
