The R-300X series is designed to measure distances at the speed of light in order to measure accurately, atmospheric correction needs to be used. The instrument is designed to correct for weather conditions automatically if the temperature and pressure are input. Correction is then carried out based on the following formula.

For this reason, the specifications illustrate the values for both good and normal weather conditions. It is extremely difficult to judge when weather conditions are “Good” and when they are “Normal”. With this instrument, the conditions noted below are used to differentiate between the two situations, (good weather conditions for surveying are different from normal weather conditions, and in surveying situations, cloudy skies are considered more favorable than sunny skies.) Weather conditions for measurement ranges are based on the following standard values: Normal: Visibility of approximately 20 km, with slight shimmer and moderate wind. Good: Visibility of approximately 40 km, overcast, with no shimmer and moderate wind. 14. NOTICE TO THE USER OF THIS PRODUCT To assure compliance with the Safety standard 21 CFR, Chapter 1. Subchapter J. The U.S. bureau of Radiological Health requires the following information to be provided to user: It can be dangerous to look into the beam with optical equipment such as binoculars and telescopes. 1) Specifications of laser radiation A) The EDM module of the R-300X pr...
