Testing Tips
• Read all instructions before testing.
• 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.
• 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.
Low pH Low pH levels can signifi cantly
lower the hardness results.
