SIM990 is portable (hand-held) combo-tester of bottom echo simulator as well as impedance tester of transducer. SIM990 will be your helpful assistant for service on board.

Echo simulator:send analog echo signal to echo sounder display.

Transducer tester:

SIM990 can be used to test most the echo sounder transducers, test their resonant frequency and resonance Impedance.

You can refer to attached transducer test reference table which lists JRC and Furuno transducers.

For other echo sounder transducers, SIM990 can test their resonant frequency and resonance Impedance.

We don’t have standard specifications of all the transducers from various manufacturers.

You can refer to the files from manufacturer or inquiry the transducers’ manufacturers, or just test one good transducer and use its result as standard reference.

SIM990 can test transducer of piezoelectric ceramics （such as Furuno, JRC, SKIPPER）, can not test transducer of inductance coil (such as Elac, Atlas, Sam)
