• Place the cuvette into the holder and close the lid.
• Press ZERO key. The display will show “-0.0-” when
the meter is zeroed and ready for measurement.
Cyanuric Acid
• Fill a second cuvette with 10 mL of the reacted sample up to the
mark. Replace the cap.
• Reinsert the cuvette into the instrument.
• Press TIMER and the display will show the countdown prior to the measurement or, alternatively, wait
for 45 seconds and press READ. When the timer ends the meter will perform the reading.
• The instrument displays concentration in mg/L of cyanuric acid.
