9.2 Fathom Related Questions
Find answers to Fathom common questions here.
9.2.1 What Is Initialization?
Initialization (also referred to as starting a study ) is an important step required to configure your
receiver correctly.
The receiver clock is always updated based on your PC clock during the initialization process. This
information will be resident with the HR2 receiver and will be available during offload, regardless of
whether you use the same computer or not. Initialization also
erases the receiver log files, so be sure to
offload data from your receiver before initializing it.
IMPORTANT: Your HR2 receiver must be initialized to remove it from Suspend Mode , and start
recording.
9.2.2 What Date/Time Format Is My Data Stored In The Receiver?
All detection data and events are stored in the receiver in UTC
1
(Coordinated Universal Time).
Fathom calculates UTC time from your computer's displayed time and zone setting, and uses this UTC
time to set your receiver's clock during initialization. Provided your computer time and the Time Zone
settings are correctly matched, (your computer time is correct for the time zone you have selected), then
your data will be correctly timestamped when stored in the receiver.
9.2.3 Why Do I See A Discrepancy Between Detections In My HR2 Live Views And Detec-
tions In The Exported CSV File?
Fathom uses some filtering criteria on detection data from HR2 receivers when they are converted from
VDAT to CSV format. This is to help
minimize the number of false detections that appear in the CSV
file.
The filters are not applied to the live views ( Live Tiles and Live Detections tabs) in Fathom, which is
why you may see a discrepancy. We think it is valuable to show all detections (both high and low
quality) in the live displays, to allow for system troubleshooting in the field.
For more information, see "HR2 Data Export Detection Filters", on page 187 .
