Note: For the most accurate results, samples over 6 ppm chlorine should be diluted
with chlorine demand free water and re-tested.
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.
