GENERAL DESCRIPTION

GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION
The HI 93734 meter measures the Free
and Total Chlorine (Cl ) content in water
2
and wastewater.
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 re-
agent is precisely dosed to ensure
maximum repeatability.
Display codes aid the user in routine
operations.
The meters have an auto-shut off feature
that will turn the instrument 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 mea-
surement 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.
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.
The "V" indicates that the
V
battery voltage is getting low
and the battery needs to be
replaced.
This indicates that the battery
is dead and must be re-
placed.
Note: once this indication is
displayed, the meter will
lockup. Change the battery
to restart.
