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 la classe A respecte toutes les exigences du

Rëglement sur le matériel brouilleur du Canada.

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

English 5

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

The 2100AN IS laboratory turbidimeter measures turbidity in FNUs

(Formazin nephelometric units), NTUs (nephelometric turbidity units) and

EBCs (European Brewing Convention units). NTUs and EBCs are

calculated using the conversion factors of 1.0 NTU per 1.0 FNU and

0.245 EBCs per 1.0 FNU. The 2100AN IS turbidimeter also measures

attenuation (FAU), absorbance and transmittance.

In addition, two user-defined measurement units can be specified. The

application specific mode of operation uses the nephelometric optical

system and the NTU measurement mode.

The turbidimeter has a built-in printer and an RS232 output for

connection to a printer, data logger or computer and a recorder output.

The turbidimeter contains a real-time clock with battery. The clock

provides a time-date stamp on all data transmitted to the built-in printer

or to external devices by way of the RS232 interface (i.e., measurements

and calibration records).

DANGER

Multiple hazards. Only qualified personnel must conduct the tasks

described in this section of the document.

Put paper in the printer

NOTICE

Use only the provided thermal paper. Use of other thermal paper may cause poor

print quality and decrease the life of the print-head.

Notes:

• Do not rub the thermal paper with a hard object.

• Do not use chemical paste on thermal paper.

• A red line on the edge of the thermal paper shows when the paper

supply is low.

1. Cut the end of the paper with scissors to make an arrow shape.

2. Open the printer cover.

3. Put the point of the thermal paper in the paper entrance slot.

4. Push the paper through until the point of the paper comes out the

exit slot.

5. Pull the paper out of the exit slot until the full width of the paper is

past the exit slot.

6. Put the paper roll in the printer.

7. Put the thermal paper through the slot in the printer cover, then close

the printer cover.
