ISUSCom 2.1.6

April 18, 2013

ISUSCom 2.1.6 now comes with a handy terminal input for issuing serial commands directly to ISUS. It also fixes a time zone calculation error that was appearing in the output of the raw data conversion function. The USB driver and operating platform have been updated to ensure full compatibility with Windows 8.

Please note that ISUSCom 2.1.6 requires a current version of the ISUS V3 firmware, which will be uploaded to your instrument when the software is installed. If your instrument is running firmware versions 3.0.3 or older, please support for assistance.

Release Summary: ISUSCom 2.1
-----------------------------------------------------------------------------------------

ISUSCom 2.1 is as an upgrade to ISUSCom 1.4.  The main focus of this release was to add
support for nitrate post processing.  In addition this a new Total Absorbance Graph view 
was added.  Finally many minor enhancements and bug fixes were addressed.

New features include:

** Nitrate Post-Processing
ISUSCom 2.1 now includes the capability to re-process previously logged data files,
eliminating the need to learn and operate the Matlab based ISUSPro program. All the functions
previously available in ISUSPro have been included in ISUSCom 2.1. The Nitrate post-processing
function enables users to experiment with different processing parameters and calibration
files to re-calculate nitrate values from challenging environments.
 
** Total Absorbance Graph
The total absorbance graph allows users to view the sampled absorption curve in real-time.
Total measured absorbance is an intermediate product of the nitrate calculation that has now
been brought out to the GUI for viewing, making quality checking of data easier and more intuitive.

** Enhanced Data Error Detection
New data integrity features in ISUSCom enable users to easily detect and view the overall number
of errors that occur within an acquisition.  This along with a fully configurable event log mechanism
gives users the ability to discover any problems that may exist within data files.

How is the ISUS V3 different from V2?

The most significant improvement with the V3 is the addition of full USB communications and data transfer ability. The V3omes with the ISUSCom software, a new Windows-based program designed to make the instrument setup and file transfer processes easier. V3 users no longer need to use HyperTerminal and Y modem transfers to retrieve data. It can all be done now at high speed with one cable in a professional windows environment. 

The ISUSCom software also offers users the ability to update the instrument sampling schedule for mooring deployments, perform in field calibrations, view and log data. It effectively consolidates functions previously performed by HyperTerminal, ISUSCal, ISUSSchedule and SatView into a single, simplified program.

How does the ISUS compensate for long term drift?

Because the ISUS is an active optical instrument with an internal UV light source and spectrometer, gradual changes in the baseline spectra can occur. To check for instrument drift, we recommend users check the baseline prior to deployments by sampling an aliquot of ultra pure de-ionized water (DIW). To do this, first clean the probe tip and warm up the instrument for 8-10 minutes. Then log 1 minute of data with the probe tip submersed in DIW, making sure that there are no bubbles present on the probe tip. If the nitrate reading for the DIW sample is >-2 or <+2 uM, the instrument has not drifted significantly. If the nitrate reading is outside this range, the instrument has drifted and should be corrected by updating the reference spectrum in the cal file. For V3 instruments, the ISUSCom software has a function to update the cal file. For V1 & V2 instruments, the ISUSCal program is required. After uploading the new cal file to the instrument, it is a good idea to run another DIW check to make sure the procedure has worked.

Can an ISUS V2 be used with ISUSCom?

No. An ISUS V2 does not have the correct hardware to be used with ISUSCom. If you have an ISUS V2, and wish to use it with this software, please contact Sea-Bird Scientific Customer Support to discuss upgrading your ISUS.

How does the free calibration differ from the fresh water calibration?

The included class-based calibration coefficients are average coefficients obtained from our library of historical calibrations. The historical coefficients that are averaged to create the class based coefficients vary by about 10%.

"Reprocess Nitrate Data" function under ISUSCom Processing Menu

The "Reprocess Nitrate Data" tool in ISUSCom allows the user to select a calibration file and a raw file.

The resulting ASCII file contains a column for the original Nitrate concentration as calculated by the ISUS, using the calibration file onboard the sensor, and a column of recalculated Nitrate using the chosen calibration file.

I am planning on doing a mooring deployment which requires relatively tightly spaced sampling. Are there any issues I need to consider when making a schedule file?

There are three main points to consider when making a new schedule:

  • Power: if you are using a battery to power the ISUS, make sure you have enough battery capacity to cover the schedule you intend to use. The ISUS draws about 7 watts of power with the lamp turned on

  • Memory: make sure the scheduled frequency and duration don't create more than 256 MB of data. The ASCII full frame is 1675 bytes

  • Lamp time: the UV lamp used in the ISUS has an effective lifetime of ~ 1000 hours. It is usually a good idea to conserve lamp hours by only collecting meaningful data
