From: Unit-specific calibration of Actigraph accelerometers in a mechanical setup – Is it worth the effort? The effect on random output variation caused by technical inter-instrument variability in the laboratory and in the field

Figure 3

Calibrated instrument output by round of quality check. Within MTI units variation: SD = 110 counts*min-1. Between MTI units variation: SD = 65 counts*min-1. Within CSA units variation: SD = 119 counts*min-1. Between CSA units variation: SD = 67 counts*min-1.
