GENERAL DESCRIPTION
The
HI 93732N
meter measures the content of dissolved
oxygen (O
2
) in
surface, feed, natural and waste waters in
the 0.0 to 10.0 mg/L (ppm) range.
The meter uses an exclusive positive-locking system to ensure
that the cuvet is in the same place every time it is placed
into the measurement cell.
The reagents are in liquid form and are supplied in bottles.
The amount of reagent is precisely dosed to ensure maximum
repeatability.
Display codes aid the user in routine operations. The meter
has an auto-shut off feature that will turn itself off after 10
minutes of non-use.

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
specifications) indicates that the sample
absorbs too much light, meaning that
the concentration is too high.
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.
The "V" indicates that the battery voltage
is getting low and the battery needs to
be replaced.
This indicates that the battery is dead
and must be replaced.
Note:
once this indication is displayed,
the meter will lockup. Change the
battery to restart.
