Certification

Canadian Radio Interference-Causing Equipment Regulation, IECS-003, Class A:

Supporting test records reside with the manufacturer.

This Class A digital apparatus meets all requirements of the Canadian Interference-Causing

Equipment Regulations.

Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne

sur les équipements provoquant des interférences.

FCC Part 15, Class "A" Limits

Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC

Rules. Operation is subject to the following conditions:

1. The equipment may not cause harmful interference.

2. The equipment must accept any interference received, including interference that may cause

undesired operation.

Changes or modifications to this equipment not expressly approved by the party responsible for

compliance could void the user's authority to operate the equipment. This equipment has been tested

and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.

These limits are designed to provide reasonable protection against harmful interference when the

equipment is operated in a commercial environment. This equipment generates, uses and can

radiate radio frequency energy and, if not installed and used in accordance with the instruction

manual, may cause harmful interference to radio communications. Operation of this equipment in a

residential area is likely to cause harmful interference, in which case the user will be required to

correct the interference at their expense. The following techniques can be used to reduce

interference problems:

1. Disconnect the equipment from its power source to verify that it is or is not the source of the

interference.

2. If the equipment is connected to the same outlet as the device experiencing interference, connect

the equipment to a different outlet.

3. Move the equipment away from the device receiving the interference.

4. Reposition the receiving antenna for the device receiving the interference.

5. Try combinations of the above.

Product overview

Maintenance

W A R N I N G

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the

document.

14 English

Clean the instrument

Clean the exterior of the instrument with a moist cloth and a mild soap solution and then wipe the

instrument dry as necessary.

Clean the cell compartment

N O T I C E

Make sure there is no sample cell or cell adapter in the cell compartment before this task is started.

Turn the instrument and use a rubber suction bulb to blow carefully air into the cell compartment.

Clean the sample cells

C A U T I O N

Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective

equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets

(MSDS/SDS) for safety protocols.

C A U T I O N

Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and

national regulations.

Most laboratory detergents are used at recommended concentrations. Neutral detergents, such as

Liquinox, are safer to use when regular cleaning is necessary. To decrease the cleaning times,

increase the temperature or use an ultrasonic bath. To complete the cleaning, rinse a few times with

deionized water and then let the sample cell air dry.

Sample cells may also be cleaned with acid, followed by a thorough rinse with deionized water.

Note: Always use acid to clean sample cells that were used for low-level metal tests.

Special cleaning methods are necessary for individual procedures. When a brush is used to clean

sample cells, take extra care to avoid scratches on the interior surfaces of the sample cells.

Replace the batteries

W A R N I N G

Explosion hazard. Expired batteries can cause hydrogen gas buildup inside the instrument. Replace

the batteries before they expire and do not store the instrument for long periods with the batteries

installed.

Refer to Install the batteries on page 7 for battery replacement.

Troubleshooting

Problem Possible cause Solution

Absorbance > 3.5! The measured absorbance is more than 3.5. Dilute the sample and repeat the
