Although most functions of the SUNA V2 can be accomplished though the USB connection, parts of the self-test require that external power be applied. In this case, connect external power and repeat the test. If the problem persists, please contact Customer Support.
The SUNA V2 determines nitrate concentrations from the shape of the UV absorption curve. The least squares curve fitting algorithm uses calibrated extinction coefficients for nitrate and bromide (strong absorbing species in salt water) to calculate the concentration...
The SUNA V2 contains a 256 channel spectrometer that is programmed to integrate for a specific length of time (usually 300 - 500 ms) while sampling to maximize signal. That is, when the SUNA V2 takes a sample, the spectrograph collects UV light for the length of the...
We recommend updating the ISUS or SUNA's reference spectrum portion of the calibration with the instrument in the same state it will be used in the field. To update the reference spectrum, you will have to run the calibration feature in ISUSCom or UCI using a pure...
The base sensing suite includes a FastCat CTD, a combined fluorescence and turbidity sensor, and a PAR sensor. The current supported list of instruments for Thetis include: CTD: SeaBird FastCat CTD (SBE49) Dissolved oxygen: SeaBird SBE43 or SBE63 Chlorophyll: ...
This is a safety feature of the instrument, whereby the lamp is turned off when its temperature reaches 35°C (95°F) to prevent damage from overheating. The SUNA continues to output dark frames while monitoring the temperature, and will restart the lamp once it has...
