The Accuracy Log details the accuracy of the NTP time received during each check-in. The accuracy value takes into account the internal time accuracy of the NTP Server, as well as any network delays. This information can also be used to review a Transmitter's check-in history.
When a Transmitter receives time from a GPS time source time accuracy is not logged, due to GPS provides a higher level of accuracy resulting from more frequent time updates.
Go to Devices > Transmitters.
