Appendix G: LISST-Black & LISST-HAB
LISST-Black and LISST-HAB are integrated packages combining a LISST-200X with
fluorometers optimized for detecting either petroleum (LISST-Black), or harmful algal blooms
(LISST-HAB). The fluorometers are Turner Designs Cyclops-7F
’s, mounted with special
brackets and cabling made by Sequoia Scientific. The LISST-200X supplies power to the
fluorometers, and digitizes their analog outputs. The digitized fluorometer outputs are
included in each data sample produced by the LISST, at rates up to one per second.
Fluorometer Output Data
The fluorometer outputs are reported in volts, included in the standard .CSV files produce by
the LISST-200X software. For format details, see Appendix C: Data File Formats. The
outputs are not calibrated to an absolute standard.
Firmware Configuration
To check that the fluorometers will be powered whenever the LISST collects data, type the
DS command at the LISST-
200x:> prompt, and look for “External sensor power during
logging: on”. If it is not on, send the command SENSORPOWER,3 . This will enable power
to the fluorometers, with a 3-second warmup before the first sample.
Power Consumption
Because of additional power consumed by the fluorometers, the LISST-Black and -HAB
cannot be reliably powered by a USB cable during sampling. A battery housing or other
power source must be connected.
