MEASUREMENT PROCEDURE
To compensate the meter for the sample turbidity or color, the measurement takes place in two
phases. First, the meter is zeroed using the unreacted sample. After the reagents are added the
reacted sample is measured.
Important note:
Free and Total Chlorine have to be measured separately with fresh unreacted
samples if both values are requested.
• Turn the meter on by pressing ON/OFF.
The display briefly shows all tags on.
