It is recommended not to touch the cuvet walls with hands.
Furthermore, in order to maintain the same conditions during the
zeroing and the measuring phases, it is necessary to close the cuvet
to prevent any contamination.

This indicates that the meter is in a ready state
and zeroing can be performed.
Sampling in Progress. This prompt appears each
time the meter is performing a measurement.
This indicates that the meter is in a zeroed state
and measurement can be performed.
A zero reading was not taken. Insert a sample
before adding reagent and press ZERO.
Under range. A blinking "0.00" indicates that the
sample absorbs less light than the zero reference.
Check the procedure and make sure you use the
same cuvet for reference (zero) and measurement.
Over range. A flashing value higher than the
maximum concentration readable (see specifica-
tions) indicates that the sample absorbs too much
light, meaning that the concentration is too high.
Dilute the sample.
Light over range. The cuvet is not inserted correctly
and an excess ambient light is reaching the
detector. If the cover is properly installed, then
contact your dealer or the nearest Hanna Customer
Service Center.
Light under range. The zero sample is too dark for
proper zeroing. If this is not the case, contact your
dealer or the nearest Hanna Customer Service
Center.
