50/200 kHz Transducer Testing
Acoustic impedance testing, ceramic ring resistance measurements, and cavitation damage checks.
Draft & Keel Offset Calibration
Verification of depth below transducer (DBT), depth below surface (DBS), and depth below keel (DBK) offsets.
IMO 12-Hour History Compliance
Testing digital memory storage and thermal chart recorder mechanisms to satisfy mandatory IMO MSC.74(69) standards.
ECDIS & VDR NMEA Data Interfacing
Verification of isolated serial RS-422 $SDDPT and $SDDBT telegram outputs feeding electronic chart displays.
