PRELIMINARY EXAMINATION

GENERAL DESCRIPTION

The HI 93700 meter measures the ammonia nitrogen

(NH

-N) content in water, wastewater and seawater in the 0.00

to 3.00 mg/L (ppm) range.

The meter uses an exclusive positive-locking system to en-

sure 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 maxi-

mum 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 ap-

pears each time the meter is performing

a measurement.

This indicates that the meter is in a ze-

roed 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. Dilute the

sample.

Light over range. The cuvet is not in-

serted 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 near-

est 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 bat-

tery to restart.
