Rogowski Coil

Large flexible current transducer typically used for measuring high currents

Alternating Current

Reporting Mode Defines how an EpiSensor node should report data to the Gateway

Reporting
Interval

The length of time between each data point produced by a node

Snap to Clock

Reporting mode where data is ‘snapped’ to the nearest 1 minute / 5 minute / 15 minute
interval etc.

Interval and
Delta

Reporting mode where data is produced when the reporting interval has elapsed, unless a
change is detected

Allow join mode A mode that can be enabled on the Gateway that allows new wireless nodes to join
