Abstract

A comparator for comparing the operation of activity monitors of the type having internal sensors responsive to excitation forces in order to record the activity of a wearer, includes a housing having a test platform and a monitor-receiving test fixture for holding an activity monitor motionless during testing. The comparator further includes an electromagnet for applying an excitation force to the monitor, by converting a prerecorded digital signal, or waveform, into analog voltage signals which are applied to the electromagnet for testing the monitor. The monitor may be subjected to a variety of test patterns of activity.
