) content in

water and wastewater in the 0 to 100 mg/L (ppm) range.

The meter uses an exclusive positive-locking system to ensure

that the cuvet is in the same position every time it is placed

into the measurement cell.

The reagent is in powder form and is supplied 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.

General Description

Specifications Display Code Guide

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"

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.
