2.2 Certification

CAUTION

This equipment is not intended for use in residential environments and may not

provide adequate protection to radio reception in such environments.

Canadian Radio Interference-Causing Equipment Regulation,

ICES-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:

4 English

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.

2.3 Product overview

The sensION™+ meters are used with probes to measure various

parameters in water.

The sensION™+ MM340 meter has two measurement channels to

measure pH, ORP (mV) or ISE (concentration) with a selective probe.

Measurement data can be stored and transferred to a printer or PC.

2.4 Product components

Refer to Figure 1 to make sure that all components have been received.

If any items are missing or damaged, contact the manufacturer or a

sales representative immediately.
