The HI 93706 meter measures the phosphorus content in
water and wastewater in the 0.0 to 15.0 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 and powder form and are
supplied in bottles and in packets. The amount of reagent
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 measurement can be
performed.
A zero reading was not taken. Insert a
sample before adding reagent and
press ZERO.
Under range. A blinking "0.0" 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 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.
