proceeding.
1. Fill a glass cuvette ¾ full with the collected sample.
2. Dry and clean all faces of the cuvette using Kim Wipes.
3. Make sure the AquaFlash is on and ready for use. Press READ.
You will be prompted to insert your sample and press READ.
4. Insert the cuvette into your AquaFlash and close the lid.
5. Press READ again and the measurement will begin.
6. Once the measurement is complete, remove the cuvette and discard
the sample.
7. Results displayed will show values for Total Chlorophyll (ug/L) as
CHL, Yield or photosynthetic efficiency as YLD, time sample was
recorded in hours:minutes, and the sample number as a 4 digit value
representing sample numbers from 1 to 1000.
8. Press the down arrow key to view Fo (minimum), Fm (maximum),
and Blank raw fluorescence values.
9. When finished viewing data, or if ready to run the next sample, press
ESC to get to the Home screen and repeat sampling procedure

Viewing Data
Data can be viewed on the Aqua display or downloaded to a computer for
viewing. To view data use the  arrow keys to scroll to a desired sample,
sample number will be displayed in the bottom right corner of the screen. Press

Quick Start Guide
Adjustable Solid Secondary Standard Procedure
The AquaFlash is factory calibrated and should remain calibrated for many
years. Calibration can be checked using the Solid Secondary Standard (SSS).
Users will first have to set the SSS using the following procedure:
1. Purchase or obtain a SSS.
2. Turn the AquaFlash on using the ON/OFF button and wait until warm up has
completed.
3. Press the CAL VAL button and record the set calibration value.
4. Loosen the small hex screw located on the back of the SSS and then holding
the SSS by the tab, insert it with the tab at the back of the sample
compartment and close the sample compartment lid.
NOTE: The AquaFlash should be on a flat surface when reading the SSS.
5. Press the READ button twice to begin measurement and look at the CHL
reading for the SSS.
a. If the CHL value displayed is lower than the calibration value, adjust the
SSS to give you a larger response by rotating the silver hex screw
located at the top of the SSS counterclockwise and re-read the SSS.
b. If the CHL value displayed is higher than the calibration value, adjust the
SSS to give a smaller response by rotating the silver hex screw located
at the top of the SSS clockwise and re-read the SSS.
6. Continue adjusting and reading the SSS until the CHL value displayed
matches within 5% the calibration value determined in step 3.
7. When finished, tighten the locking screw on the back of the SSS by turning

repeat steps 3 9 until the SSS is properly adjusted. It is recommended that
users make 5 consecutive measurements of the SSS after it is set to ensure it is
properly adjusted.
The SSS can now be used to periodically check for instrument drift.
