2.8 Testing the Receiver
Before deploying an HR2 Receiver, we recommend that you
conduct in-air tests
with one or more tags
to:
1. Familiarize yourself with operating Fathom software and HR2 receivers. The air test
will allow you to go through the process of connecting to an HR2, activating a tag and
using Fathom to conduct a new study and upload data, etc.
2. Test your tags and receivers before implanting tags into your fish. If any problems
arise we would like to know beforehand, rather than on the day you are conducting
surgery and releasing fish or deploying receivers.
IMPORTANT: Handle 180 kHz tags with care . Do not squeeze the tags. Avoid using metal forceps.
Do not shock the tags
with instruments that carry static charge.
If you drop a tag on a hard surface you should test the tag to see if it still functions and you should
record it in your notebook (ID code & Serial Number). Our tags have a medically inert coating of
Parylene. If you scratch the tag you might damage the coating.
Tests can, and should, be done in both air (see "In-Air Test", below ), and water (see "In-Water Test",
on the next page ).
2.8.1 In-Air Test
The HR2 can detect coded tags and communicate with a VR100-200 in air but does so at a much
reduced range compared to its range capabilities when it is in water.
IMPORTANT: Perform in-air tests away from electrical noise sources such as motors, PC screens, or
fluorescent lights.
To perform an in-air test
Acoustic high frequency signals do not transmit well through air. To conduct the test the tag or tags need
to be
touching or very close to the HR2 hydrophone (millimeters, see image).
1. Connect receiver to computer (see "Connecting an HR2 Receiver to a
computer", on page 18 ).
2. Launch Fathom software (see "Launch Fathom", on page 20 ).
3. Establish communication with receiver (see "Establishing Communication",
on page 24 ).
4. Ensure receiver's built-in transmitter is
ON
(see "HR2 Transmitter Tab", on page 44 ).
5. Start a study (see "Starting a Study", on page 67 ).
6. Select the Live Detections tab.
7. Activate your 180 kHz tag(s) and place it less than 2.5 cm (1”) away from the HR2
hydrophone (tip) so the side of the tag is facing the side of the hydrophone.
