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.

MEASUREMENT PROCEDURE

• 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.

• Press ZERO/CFM and the lamp, cuvette

and detector icons will appear on the
display, depending on the measurement
phase.

• After a few seconds, the display will

show “-0.0-”. The meter is now zeroed
and ready for measurement.
