ColorQUser Tips
!Always rinse tubes and caps after testing.
Reagent left behind can affect the next test or
stain the tube.
Error Messages
Use a small Phillips head screwdriver to
remove all 5 screws in the base. Gently pull
the battery holder from the inside and
replace TWO AA style batteries. Replace
screws securely but do not over-tighten
screws which can tear the rubber base.
bAt = Battery is low.
Maintenance
Battery Replacement
Hi = Result is above the effective measuring
range for the system (e.g. >9.0 pH for Code
7059 reagent.)
!Replace stained or scratched tubes (0201).
!Clean ColorQ optics with a damp cotton
swab. Avoid abrasive cleaners that can
damage plastic.
Do not use brushthe test tube to clean
the ColorQ meter chamber.
!Be sure the outside of the tubes are dry
before putting them into the ColorQ. This
is best accomplished by dispensing the
water sample from the sample bottle.
!Replace liquid reagents annually. To learn
more about reagent storage guidelines and
shelf-life go to Support Section then Reagent
Refills/Shelf Life at www.lamotte.com.
Low pH Low pH levels can significantly
lower the hardness results.
Er 3 = Insufficient light is reaching the
detector. Sample may be too dark, or tube
may be in sideways. Turn off meter and
retest.
Er 7 = The blank was not properly set. Turn
off meter and retest blank making sure the
black arrow on the tube is facing forward,
toward the user (not left or right).
SUN = Extremely bright sunlight is
penetrating the chamber. Turn your back to
the sun to shade the meter from bright
sunlight.
Lo = Result is below the effective measuring
range for the system (e.g. < 4.0 pH for
Code 7059 reagent.)
!If not testing all tests in the sequence,
follow blanking procedure and then press
button until desired test factor is shown.
Follow test procedure.
!In one complete inversion, the tube will be
turned cap down and then right side up.
The air bubble will move slowly to the
bottom of the tube and back again to the
cap end.
!If small bubbles form after adding
reagents, tap bottom of tube sharply once
or twice to dislodge bubbles. Bubbles will
interfere with the test results.
!Samples with concentrations greater than the
range of the reagent system must be diluted.
Add 2.5 mL of sample water to a test tube.
Fill to the 5 mL line with distilled or deionized
water. Cap and mix. Blank with the diluted
sample. Follow the test procedure with the
diluted sample. Multiply the displayed result
by 2. (This will not work for the pH test).
