The unit is easily configured using the included Track-It Software. Simply plug the logger into an open USB port on your PC and the software automatically identifies the logger. Configure the unit to start and stop recording immediately, at a predetermined time and date, or only when an alarm condition is sensed. The sample storage rate can be set from 1 sample every 2 seconds up to 1 sample every 24 hours. The on board data storage is non-volatile so data will not be lost in the event of a depleted battery. Barometric (also known as atmospheric) pressure can be displayed in a variety of engineering units. It can be used as an altimeter. Information displayed on the LCD is user selectable and can be sequenced by pressing the logger button. There is a multicolored LED indicator to notify user of alarms or general activity. A splash proof protective cover protects the logger when in use. Additionally, the logger can be used to record external inputs using optional Track-It DC voltage or DC current modules.
