6. The instrument constant is a numerical value used to automatically correct for the displacement between the mechanical and electrical centers when measuring distances Although this adjustment was made at the time of delivery it is recommended that the constant be checked several times a year to ensure the highest operational accuracy Checks can be performed by either comparing a correctly measured base line with the distance as measured by the EDM or by using the following procedure About 100m ee 1 Perform the check on as flat an area as possible Set up the DTM 400 at Point P with the reflector prism 100m away at Point Q taking the prism constant into account 2 Measure the distance between Points P and Q and note it for future reference 3 Set up another tripod between the two at Point R and transfer the DTM 400 to it Install a reflector prism back on the tripod at Point P SPECIFICATIONS V SPECIFICATIONS 1 Main Unit eTelescope Image Erect unreversed Magnification 26 Effective diameter of objective 36mm Field of view 1 30 Minimum focusing distance 1 0m Resolving power e Distance Measurement Distance range of Nikon prisms 450m with mini prism 1000m with single prism 1200m or longer with triple prism x With visibility 40km 25miles Precision 5mm 3ppm x DJ x With accurate measurement mode at 1O C 40 C 14 F 104 F D is measuring distance mm uni
