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
