Earth curvature and meanrefraction coefficient (k = 0.13) are taken intoaccount automatically. The calculated horizontaldistance relates to the station height, not to thereflector height.= D 0 · (1 + ppm · 10 -6 ) + mm= displayed slope distance [m]D 0 = uncorrected distance [m]ppm = scale correction [mm/km]mm = prism constant [mm]= Y - A * X * YHeight measurement1) Mean sea level2) Instrument3) ReflectorTechnical Data151= X + B * Y 2= horizontal distance [m]= height difference [m]<strong>TPS400</strong>-5.0.1en
