Note: To measure exactly 5 mL of reagent with the syringe, push
the plunger completely into the syringe and insert the tip into
HI 93734B reagent bottle. Pull the plunger out until the lower
edge of the seal is on the 5 mL mark of the syringe.
• Fill the cuvet up to the 10 mL mark
with 5 mL of unreacted sample, using
the 3 mL plastic pipette.
Note: rinse the 3 mL plastic pipette 2
or 3 times with sample before adding it
to the cuvet with reagent.
• Replace the cap and shake gently.
• Place the cuvet into the holder and
ensure that the notch on the cap is
positioned securely into the groove.
• Press ZERO and "SIP" will blink on the display.
• Wait for a few seconds and the display will
show “-0.0-”. Now the meter is zeroed
and ready for measurement.
