Radio transmitter RT 06
Radio transmitter
RT 06
can
be operated with various sen-
sors, EM30 microphones and
the HA hydrophone. It is rec
-
ommended to use active filter
ZF01 if you want to filter out
interference noise or if you
only want to transmit a certain
acoustic frequency range to
correlator
AC 06
.
CAUTION!
Always connect the
sensor to the measuring point
first (connect microphone to slide gate, hydrants
etc.) before switching on the
RT 06
by plugging the
sensor into the socket (2).
This ensures that the automatic amplification in the
RT 06
is set quickly and correctly.
The
RT 06
is switched on by plugging the sensor into the socket
(2).
Always press the filter key (4) for plastic piping. The right LED
(5) lights up to indicate the switch. At this setting only the lower
frequencies (low pass) are transmitted to the correlator by radio.
This often increases the quality of the correlation measurement.
Every time the RT 06 is switched on all frequencies are transmit
-
ted and the left LED (6) lights up.
The carrying knob attached to the top of the aerial is ideal for
transportation.
The LED (1) indicates the status of the
RT 06:
Operation:
green
Undervoltage:
flashing red
Charging:
1 x flashing green
Buffering:
2 x flashing green
Not
charging:
