The calibration of a HP 3800B distance meter yields two kinds of data. The first is the instrument-reflector constant which must be applied to each measurement. The second is the nonlinear sinusoidal error curve, which repeats itself each 10 m and which must be accounted for in order to maintain high precision for short lines. Application of the results to a small quadrilateral observed in order to monitor fault slippage yields a standard error of plus or minus 0.0007 m after adjustment. The average length of the sides is 180 m. The standard error of the measurements is about 4 ppm of the average length of the sides. /Author/
