1D parameters and datum points

Hi

How I can type leveling standard? I need to put value of 1mm/km of 2mm/km [image]
if you see picture there is oa, ob(sqr(d)) and oc(d) so in which area I need to put 1 or 2, or I need to put something else?

also I want to ask for datum points. what is difference between reference and datum point?
if I want datum on all points I need to upload file only in datum points?

if I want for example datum on one point, I need to upload file with one point in datum points and file with rest of points in new points?

if is it correct for wat I can use reference points?

Thanks and best regards!
