When the transmitter is on:
• Short press will cycle the transmitter between low and high radio power output.
• Long press (2 seconds) will turn off the transmitter (press and hold until all the LEDs come on
and go off).
3.1.4 LED Level Indicator
At first switch on, the LED level indicator will give a representative indication of battery charge; full
charge is indicated by 5 LEDs and minimum charge by a single LED. After a short while the display
will change mode and give an indication of the sound level picked up by the transmitter. A single LED
shows a low sound level; all LEDs indicate the highest sound level.
3.1.5 Battery LED
The LED shows green when the transmitter is switched on. The LED will show red when the battery
charge is low; the transmitter should then be charged.
3.1.6 Radio Power LED
The radio power LED shows the transmit power setting of the transmitter. Green indicates low power,
yellow indicates high power. Low power needs to be used when the transmitter is near PrimeTouch
(within 20metres).
3.1.7 External Sensor/Charger Socket
The connector allows the connection of external sensors and also connects the transmitter to the
charger when it is in the transport case.
3.1.7.1 External Accelerometer
The external magnetic accelerometer sensor is used where the location of the transmitter does not
allow the easy attachment of the internal accelerometer to a pipe or fitting. This also allows the option
of placing the transmitter above ground to improve the radio signal between the transmitter and
PrimeTouch. A metal plate can be attached to the bottom of the transmitter to provide stability to the
unit. External accelerometers from previous Eureka correlation units are compatible with Eureka3
transmitters.
3.1.7.2 Hydrophone
Hydrophones can be purchased separately to improve noise quality for large diameter (typically
>300mm) and plastic pipes, or even for sites with excessive background noise. A hydrophone can be
attached to the transmitter and directly inserted into the pipe through a hydrant or similar fitting. This
option then needs to be selected on PrimeTouch.
Adhere to local water hygiene regulations when
inserting hydrophones into potable water pipes.
The Eureka3 software must have the correct
information about the sensors connected.
3.1.7.3 Transmitter Charging
The transmitters are charged in the transport case. To charge, connect one of the charge leads in the
transport case to each transmitter. Connect the transport case to the mains supply using the mains
adapter or use the vehicle charge cable (12Vdc).
