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 with
tube positioning ring should be used for the blank and the reacted sample.
Dilution Procedures
Samples and standards may be diluted with distilled or deionized water.
Standard Solutions
The meter has been calibrated with colored standards of known concentrations of
platinum cobalt. One unit of color is equivalent to the color that is produced by 1 mg
platinum/L in the form of the chloroplatinate ion. A 500 cu Color Standard (60 mL,
Code 6058-H) is available from LaMotte.
