The Motor101 measures and records on and off status changes for motors or other equipment drawing up to 200 Amps. The state change occurs when the current switch exceeds the 150mA set point. This allows for most basic equipment to be monitored. The current switch monitors whether there is current passing through a wire around which it is clamped. When the current exceeds 150mA’s, the output changes and provides a voltage for the Motor101 to measure.

All data is date and time stamped and the duration of the on or off status is also provided (see graph screen shot below). The LED on the Motor101 blinks at the user specified reading rate. The device can hold up to 32,767 state changes, but memory will only be used if the status has changed. The device can be programmed to check for status changes every 1 second, up to once every 12 hours.
