Initial jobs completed at Newcastle had shown that methods for field calibration of ADCP compasses seem to be well known, however, many users seemed to be unaware of the need for workshop calibration of compasses. In particular calibration is required after exchange of a PIO board. Grant said that one ADCP that had been received with a 20 to 30 degree error and that this had been successfully analysed and corrected.With an increased focus on ADCP data quality UVS is pleased to provide compass calibration in Australia for Teledyne RDI ADCPs. The ADCP “Silver Service” capability combines ADCP Overhaul with Verification and Validation including compass accuracy checks, pressure sensor accuracy checks and software and hardware checks for latest updates. Beam continuity, sensor and crosstalk checks ensure that your instrument is in a known condition prior to deployment and comprehensive reporting is included for your records. Calibration, fault-finding and upgrades can be completed as required when the results of checks are known.

UVS is constantly working on improving our capability for ADCP service and our “Gold Service” will be available in late 2014. This will include full ADCP refurbishment combined with a Verification and Validation service. Future service offerings will include dynamic “side-by-side” testing of ADCPs against the UVS Gold Standard for ultimate confidence in ADCP performance.
