Data Collection and Calculating Results Scale Resolution – no better than one-half of the smallest division
Data Collection and Calculating Results Digital Meter Accuracy – specified as +/- (percent of reading + number of units in the least significant digit) Example: Stated accuracy: +/- (0.5 + 2) Scale reading of 1000 for Figure 7.10 1000*0.005+2 = +/- 7 volts
