YSI 9600 - Manual (Page 56)

you will need to set up the DCP software to issue the proper command to receive data from the 9600.
You will again be required to consult you DCP manual to complete this software set-up.
IMPORTANT: Remember that, no matter whether a YSI 6200 or another DCP is used with the 9600, you
MUST ACTUALLY START A DEPLOYMENT using NUview software before detaching the instrument
from your PC and connecting it to the DCP.
5.6 9600 POST DEPLOYMENT CHECK – QUALITY
ASSURANCE
After completing a field deployment study, YSI recommends that you carry out one of the following
protocols to assess the performance of your 9600. Note that the first protocol is the one recommended by
YSI.
• PREFERABLE: At the time of recovery, DO NOT STOP THE STUDY. After removal of the 9600
from the water at the site, reattach the second standard bag containing the predeployment check
standard solution to the inlet port after removing the inlet filter. Take the 9600 to your laboratory and
let it run for a few hours with the second standard bag attached. Be sure to tape the second standard
bag to the top of the analyzer as shown in Section 4.4 above. Compare the nitrate-N concentration
readings recorded after attachment of the second standard bag with the known value to determine the
quality of the 9600 performance.
• ACCEPTABLE: At the time of recover, STOP THE STUDY. After removal from the water at the
site, take the analyzer to the laboratory and reattach the second standard bag containing the
predeployment check standard solution to the inlet port after removing the inlet filter. Run a
“Predeployment Check” and determine if any errors are observed at the end of the test. If no errors
occur, the analyzer performance for the run was probably within specifications. If errors are observed
after the test, note the form of the error and the absorbance readings on the screen and contact YSI
Technical Support to assess the extent of the effect the presence of errors might have had on your
deployment data.
5.7 9600 MAINTENANCE AND NEW DEPLOYMENTS
After your 9600 has been brought to the laboratory after a deployment, perform the following routine
maintenance operations prior to the next deployment of the instrument:
• Remove the carousel from the outer shell and set it on a flat surface such as the floor or a bench top.
• Close the pinch clamps on all bags (reagent and waste).
• Inspect the tubing for pinch points and repair or replace the tubing (contact YSI Technical Support if
any problems are found).
CAUTION: There are still hazardous chemicals in the reagent and waste bags and cadmium
column assembly after the deployment is complete. Therefore, it is very important to wear
appropriate personal protective equipment including safety glasses with side shields and use
disposable gloves when handling solid chemicals and when preparing and transferring
solutions of these chemicals.
