Threshold
The threshold is the first "level" of the StepWatch's sensitivity to acceleration. At the time of manufacture, the threshold is calibrated in "G-force" response to a resolution of 0.001 G. The threshold is stored to the StepWatch memory.
You can see your StepWatch's threshold by using the Read Current Settings... command in the Utilities section of the Monitor menu or by launching Advanced Programming. Your monitors' threshold value is also recorded on the calibration sheet provided with your StepWatch, and shown on the summary window of a downloaded file.
If you are using the Advanced Programming to start your StepWatch, be sure to check that you have selected the desired Sensitivity to match the monitor's threshold before you send the monitor out on a data collection session.
