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 numèrique 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.

4

English

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.

W A R N I N G

Explosion hazard. Incorrect battery installation can cause the release

of explosive gases. Be sure that the batteries are of the same

approved chemical type and are inserted in the correct orientation. Do

not mix new and used batteries.

W A R N I N G

Fire hazard. Battery substitution is not permitted. Use only alkaline

batteries.

N O T I C E

Make sure to tighten the screws to 11 N·m (8 ft·lb) for a correct seal fit and to

Install the sample cell and cell adapter

The instrument has one cell compartment which can use one adapter for

different sample cell types. Make sure to install the sample cell in the

correct orientation and in a consistent orientation so that the results are

more repeatable and precise. Refer to Figure 4. Close the instrument

cap before the instrument zero is set or a measurement is made to

prevent light interferences. Refer to Figure 5.

Maintenance

W A R N I N G

Multiple hazards. Only qualified personnel must conduct the tasks

described in this section of the document.

Clean the instrument

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

solution and then wipe the instrument dry.

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 when regular cleaning is

necessary. To reduce the cleaning times, increase the temperature or

use an ultrasonic bath. To finish the cleaning, rinse a few times with

deionized water and let the sample cell air dry.

Cells may also be cleaned with acid, followed by a thorough rinse with

deionized water.

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

Special cleaning methods are necessary for individual procedures.

When a brush is used to clean cells, take extra care to avoid scratches

on the inner surfaces of the 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.

English 15

W A R N I N G

Fire hazard. Battery substitution is not permitted. Use only alkaline

batteries.

N O T I C E

Make sure to tighten the screws to 11 N·m (8 ft·lb) for a correct seal fit and to

maintain the enclosure environmental rating.

Refer to Install the batteries on page 6 for battery replacement.

Zertifizierung

Kanadische Vorschriften zu Störungen verursachenden

Einrichtungen, IECS-003, Klasse A:

Entsprechende Prüfprotokolle hält der Hersteller bereit.

Dieses digitale Gerät der Klasse A erfüllt alle Vorgaben der kanadischen

Normen für Interferenz verursachende Geräte.

Cet appareil numèrique de classe A répond à toutes les exigences de la

réglementation canadienne sur les équipements provoquant des

interférences.

FCC Teil 15, Beschränkungen der Klasse "A"

Entsprechende Prüfprotokolle hält der Hersteller bereit. Das Gerät

entspricht Teil 15 der FCC-Vorschriften. Der Betrieb unterliegt den

folgenden Bedingungen:

Deutsch

19

1. Das Gerät darf keine Störungen verursachen.

2. Das Gerät muss jegliche Störung, die es erhält, einschließlich jener

Störungen, die zu unerwünschtem Betrieb führen, annehmen.

Änderungen oder Modifizierungen an diesem Gerät, die nicht

ausdrücklich durch die für die Einhaltung der Standards verantwortliche

Stelle bestätigt wurden, können zur Aufhebung der

Nutzungsberechtigung für dieses Gerät führen. Dieses Gerät wurde

geprüft, und es wurde festgestellt, dass es die Grenzwerte für digitale

Geräte der Klasse A entsprechend Teil 15 der FCC-Vorschriften einhält.

Diese Grenzwerte sollen einen angemessenen Schutz gegen

gesundheitsschädliche Störungen gewährleisten, wenn dieses Gerät in

einer gewerblichen Umgebung betrieben wird. Dieses Gerät erzeugt und

nutzt hochfrequente Energie und kann diese auch abstrahlen, und es

kann, wenn es nicht in Übereinstimmung mit der Bedienungsanleitung

installiert und eingesetzt wird, schädliche Störungen der

Funkkommunikation verursachen. Der Betrieb dieses Geräts in

Wohngebieten kann schädliche Störungen verursachen. In diesem Fall

muss der Benutzer die Störungen auf eigene Kosten beseitigen.

Probleme mit Interferenzen lassen sich durch folgende Methoden

mindern:

1. Trennen Sie das Gerät von der Stromversorgung, um

sicherzugehen, dass dieser die Störungen nicht selbst verursacht.

2. Wenn das Gerät an die gleiche Steckdose angeschlossen ist wie das

gestörte Gerät, schließen Sie das störende Gerät an eine andere

Steckdose an.

3. Vergrößern Sie den Abstand zwischen diesem Gerät und dem

gestörten Gerät.

4. Ändern Sie die Position der Empfangsantenne des gestörten Geräts.

5. Versuchen Sie auch, die beschriebenen Maßnahmen miteinander zu

kombinieren.
