The measurement increment should be increased to 0.1. extremities of each of these grades. Correction for Slope
Most of the time, the precision of a measurement system is reported as an estimated standard deviation. These errors, caused by the imperfections in the construction or adjustment of instruments, affect all measurements alike. probable errors in base line measurements. If the measurement increment is too large, you will need to decrease the measurement increment so it is within the range. %
