Electro-Chemical Devices (ECD) HCA1 - Manual (Page 12)

8. Minimize exposure of meter and test reagents to heat above 32°C (90°F).
9. Dry the outside of the meter when testing is complete or before storage of the
meter.
10. When running a DPD-1 Free Chlorine test AFTER a Total Chlorine DPD-4, or a
HR Free Chlorine test, rinsing is very important to remove residual KI, which
may interfere.
11. Each HCA1 Strip Micro is valid for ONLY one test. Discard strip after single use
in regular refuse that is inaccessible to children and pets.
12. Each bottle of HCA1 Strip Micro contains, at minimum, the quantity of strips
notated on the bottle. Due to the strip slitting process, you may find one or
two extra strips that are noticeably smaller or larger in width than the normal
strips in the bottle. These should be discarded. Using these strips may give
incorrect results.
13. The HCA1 Chlorine Plus Meter is not compatible for use with DPD-1, DPD-3,
and DPD-4 powder pillows, tablets, or liquids available from other
manufacturers. Accurate results can only be guaranteed by using genuine
HCA1 Micro strips or reagents (reorder information below).
14. Lab testing with the Chlorine Plus meter has shown that zeroing and
measuring of the sample normally does not require any cell cover for accurate
results, except in sunlight. To obtain optimal accuracy when testing with the
meter outdoors (sunlight), use the Mixing Cap/Cell Cover when zeroing and
reading the sample.
15. Remove batteries when meter is not used for more than a month (Warranty
Requirement).
HCA1 Chlorine Plus Meter Messages
Message Description Corrective Action
Hi
In READ mode: test sample
concentration is above the
measurement range (test specific).
Dilute and retest. Dilution Kit
available
Lo
In READ mode: test sample
concentration is below the
measurement range (test specific).
Sample value is below
measurement range.
Lo
In ZERO mode: sample absorbance
(due to a cloudy or colored sample
or a dirty cell) is too high to zero,
the meter will read “LO”.
Dilute sample, filter sample, or
clean cell. One of these options
should remedy the problem.
ER
Excessive stray light detected.
Normally this does not occur, even
when testing in sunlight.
Place the LIGHT BLOCKING CAP
over the CELL for zeroing and for
reading result.
Low battery indication. Replace the batteries.
