ADS Eureka2R Leak Noise Correlator User Manual

Connections

Based on the application, a Eureka2R may be operated in one of the following
ways:
Using two radio transmitters

Using one radio transmitter and a direct connection to an

accelerometer or hydrophone
Using a direct connection to a single accelerometer sensor

Make all direct connections to the same port, located next to the printer port
on the right side of the instrument. This port also serves as the connection
port for the battery charger and the communication interface between the
Eureka2R correlator and a PC.
When applicable, connect headphones to the port on the bottom edge of the
instrument.

Positioning the Correlator Antenna

When in use, rotate the antenna from the stowed position below the instrument
to a vertical position on the left side. If the antenna is difficult to rotate,
loosen the retaining ring. However, effective radio signal reception can often
occur with the antenna in the storage position (i.e., folded beneath the housing
of the correlator). ADS recommends using the antenna in this position unless
radio reception is poor.
Occasionally, when using the correlator (with an extended antenna) very close
to one radio transmitter while a very weak signal is coming from the other
transmitter, a center correlation (i.e., Td = 0.00 feet per second) may display.
Prevent this condition by moving the Eureka2R away from the closer
transmitter.
