Step 11
Insert the reference sample then take a reference
measurement using the reference key.
The acquired reference sample baseline will be applied
to all subsequent sample measurements.
Step 12
Replace the previous sample with a test sample then
take a sample measurement using the confirm key.
Repeat for all samples.
WARNING!
Previous measurements cannot be recalled so should
be printed or output to a USB flash drive before any
subsequent samples are measured.
Results
The results are displayed on the screen. Use the left and right arrow keys to move the cursor and display
the absorbance at each interval position.
Return to the Applications screen using the escape key OR display the options menu using the options key
(see the “Additional Options” section).
Standard Curve
The Standard Curve application is accessed from the Applications screen using the ‘5’ key. It can be used to create
a calibration curve from standard samples of known concentration. The curve fit equation is then applied to the
absorbance (A) measurements of any subsequent test samples to determine their concentration.
