Thank you for choosing a Hanna product. This manual will

operation of the meter. Please read it carefully before using

the meter. If you need additional technical information, do

Each Ion Specific Meter is supplied complete with

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.
