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.
• 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 cuvet with 10 mL of unreacted
sample, up to the mark, and replace the
cap.
• Place the cuvet into the cuvet holder and
ensure that the notch on the cap is
positioned securely into the groove.
• Press
ZERO/CFM
and the lamp, cuvet
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.
