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.
•  Turn the meter on by pressing 

ON/OFF

. The display briefly shows all tags on. 

•  When the beeper sounds briefly and the LCD displays dashes, the meter is ready. The blinking 

“ZERO”

 indicates that the instrument needs to be zeroed first.

•  Fill the cuvette with 10 mL of unreacted sample, up to the mark, and replace the cap.

•  Place the cuvette into the cuvette holder and ensure that the notch on the cap is positioned 

securely into the groove.
