It really defines how precise your measurement system can be and defines a range of effective increments for your measurement system. each section of a base line is separately corrected. In Dr. Wheelers words: No measurement should ever be interpreted as being more precise than plus or minus one Probable Error since your measurement will err by this amount or more at least half the time.. It is used to gauge how effective an improvement or change initiative is. l = Nominal length of measuring unit The rear ends of the tape are connected, to the straining posts and forward end of spring balance. 2. The blunders or mistakes result into large errors and thus can easily be detected by comparing with other types of errors (generally small in value).

An analysis of the source of errors leads to the following classification of errors. 2 0 obj the ground surface at intervals slightly less than one tape length. or Vertical Alignment: This correction is if the two measurement agree, The measurement of a long baseline may sometimes be difficult due to obstacles or the level, ground being of limited extent, only portion of the baseline accurately measured which is then, prolonged by ranging lines in continuation of it, at one or both ends, suitable lengths obtained, to give well- conditioned angles from its end to the points to be fixed. Cg = corr for slope base. B1, b2------------ = Difference of elevation b/t the extremities of each of these grades. probable errors in base line measurements - bigbangblog.net The measurement increment should be increased to 0.1. After mistakes have been detected and eliminated from the measurements, the remaining errors are usually classified either as systematic or random error depending on the characteristics of errors. Cs/ = Sag correction for any tape length, The normal tension of a tape is a tension which will cause the effects of pull and sag to neutralize each other.
