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.

• Fill a beaker up to the 25 mL mark with

the sample, add the content of one packet
of HI 93722-0 reagent and swirl gently
to mix. This is the reacted sample.

reacted sample, up to the mark, and
replace the cap.

holder and ensure that the notch on the
cap is positioned securely into the groove.
