1. Turn the meter on by pressing the button. All segments are displayed. When the display shows “Add”, “C.1” with “Press” blinking, the meter is ready.

2. Fill the cuvette with 10 mL of unreacted sample and replace the cap. Place the cuvette into the meter and close the meter’s cap.

3. Press the button. When the display shows “Add”, “C.2” with “Press” blinking the meter is zeroed.

4. Remove the cuvette from the meter and unscrew the cap. Add the content of one packet of HI702-0 reagent. Replace the cap and shake gently for about 15 seconds. Place the cuvette back into the meter.

5. Press and hold the button until the timer is displayed on the LCD (the display will show the countdown prior to the measurement) or, alternatively, wait for 45 seconds and press the button.

6. The instrument displays the concentration of copper in ppm. The meter automatically turns off after 10 minutes.

• It is important that the sample does not contain any debris.

• Whenever the cuvette is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil and dirt. Wipe it thoroughly with HI731318 or a lint-free cloth prior to insertion.

• Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.

• Do not let the reacted sample stand for too long after reagent is added, as accuracy will be affected.

• After the reading it is important to immediately discard the sample, otherwise the glass might become permanently stained.

To save the battery, the instrument shuts down after 10 minutes of non-use. One fresh battery lasts for a minimum of 5000 measurements. When the battery is dead the instrument will display “bAd” then “bAt” for 1 second and then turns off. To restart the instrument, the battery must be replaced with a new one.

To replace the instrument’s battery:

• Turn the instrument off by holding the button until the meter shuts off.

• Turn the instrument upside down and remove the battery cover with a screwdriver.

• Remove the battery from its location and replace it with a new one, inserting the negative end first.

• Insert the battery cover and replace the screw with a screwdriver.
