Diagnostics of the ESN100 using an ETT985
e ETT985 echosounder and transducer tester has been updated with tests for the ESN100 echosounder
and the new transducers ETS50200 and Furuno 8B-200B. ese updates can be downloaded from the skip-
per website when the ETT soware is started.
Connecting the ETT985 to the transducer ports of the JB50E1-SA unit and then running the ESN100 noise
test for the appropriate frequency will allow the user or service technician to check the signal output and
noise characteristics of the system.
Using the transducer tester, the connected transducers can be analyzed to see if their resonance impedance is
as expected.
