Nikon DTM-300 manual or adjustment instructions

I've pulled a DTM-300 out of the closet after a company merger and I don't have the user manual.  I did a quick field test and found that it needs a vertical/horizontal angle adjustment.  Does anyone have a manual with instructions on how to do a field adjustment?

  • Hi Dennis, A friend of mine asked me this  not long ago but it wasn't  on a Nikon.

    This was used when you could not or did not have the time to have the instrument  service by a tech.

    But in days gone by it has help me a lot. Pegging a Total Station in the field maybe a lost  function

    of surveying with today's modern Guns. There are still a lot of older instruments still being used that are just as accurate as today's instruments. I did have the manual for the 300 but it's filed somewhere but I founded the 302 manual,it is very similar I am sure you can use it to help. But this page is at Land surveyors United. I use to know the  short cut keys to do this  but the other works just as well. Look in Chapter 6 page in book #168  also pdf page #188.

    Are you not using a Data Collector with the Gun,most have collimation programs to correct this,without correcting the gun. But I agree it is best to correct it. Maybe this manual will help.

    Best Regards,

      Thanks Billy!  I don't know how I missed the Land surveyors United page on 'Vertical Zero Datum', but that's exactly what I'm looking for.

    • Hi Dennis,

      Welcome ,to the site .Glad something help.If I find the 300 manual,I will pass it on to you.

      I have the real book and the pdf file on a cd somewhere or on a older computer.

      The book maybe in storage,since I moved.

      I had good luck with the Nikon's I have used.

      Thanks for the shout back,
