NOTE: The meter will remember the last scanned blank reading. It is not
necessary to scan a blank each time the test is performed. To use the
previous blank reading, instead of scanning a new one, scroll to Scan Sample
and proceed. For the most accurate results, the meter should be blanked
before each test and the same tube should be used for the blank and the
reacted sample.
NOTE: For the best possible results, carry a reagent blank through the
procedure. After scanning the blank, perform the test procedure on clear,
colorless, distilled or deioized water. Subtract results of regent blank from all
subsequent test results.

STANDARDS
The meter should be calibrated with sulfate standards. The calibration should

similar to the expected concentration of the sample that will be tested.
