FILL METER WITH SAMPLE
4
Rinse the CELL 2 or 3 times with the water sample you will be testing - rinsing minimizes
the potential for cross-contamination from a previous test. Finally, fill cell to capacity (4ml)
with the water sample.

move across the display, informing you that it is about to measure the sample. Record result
displayed (this result is automatically stored in CA5). After testing is completed, rinse cell
immediately.
CA5: Calcium reacts with Oxalic acid as it is released from the strip to form a white precipitate, directly
proportional to the Calcium concentration. Values are reported as Calcium Carbonate.

color development). At 20 sec, the cursor will move across the display, informing you that it is
about to measure the sample. Record result displayed (this result is automatically stored in CU6).
After testing is completed, rinse cell immediately.
CU6: Copper reacts with Biquinoline or Bicinchoninic Acid as it is released from the strip to form a purple color,
directly proportional to the copper concentration.
