Connecting A Probe - GE USM 36 Series Technical Reference And Operating Manual

Connecting a probe

3.3 Connecting a probe
To prepare the USM 36 for operation, you have to con-
nect a probe to it. Any GEIT probe can be used for the
USM 36, provided the appropriate cable is available and
the operating frequency is within an adequate range.

If a probe is connected incorrectly, the con-
sequence would be a mismatching which
may lead to considerable power losses or
even to echo waveform distortions.
The probe is connected to the sockets on the top of the
instrument casing.
USM 36
Both connector sockets are equally suitable (connected
in parallel) for connecting probes equipped with only
one ultrasonic element (ultrasonic transducer) so that it
does not matter which one of the two sockets is used.
When connecting a dual-element (TR) probe (having
one transmitter or pulser element and one receiver ele-
ment) or two probes (of which one is transmitting and
the other one receiving), attention should be paid to the
correct allocation of connecting cables:
Red ring – receiver connection
Black ring – transmitter/pulser connection
