minimizes the potential for cross- contamination from a previous test. Finally, fill cell to
capacity (4ml) with the water sample.

Press READ again and the meter will count down and display the next Total Chlorine result.
If this reading matches the previous result, then record this as Total Chlorine result. This
result is stored in CL1. If reading has increased by 0.01, press READ again and repeat.
After testing is completed, rinse cell immediately. Record the Total Chlorine as the highest value
the meter displayed.
NOTE: Standard Method (4500-Cl G, procedure for total chlorine) requires the reading to be
made 2 minutes after the reagents are added.
