the sample too long. A
measurement error occurred.
Remove the Chemkeys immediately when prompted.
The sample detector pin area
is dirty if the warning shows
while the meter is not in the
sample.
Clean the sample detector pin area. Refer to Clean or
replace parts on page 18. If the problem still occurs,
contact technical support.
Over Range The concentration is more
than the upper limit of the
current method.
Dilute the sample and do the measurement again.
Under Range The concentration is less than
the lower limit of the current
method.
