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.

2.3 Product overview

Fire hazard. This product is not designed for use with flammable liquids.
The TL2350 laboratory turbidimeter measures the scattered light from water samples to determine
the turbidity value of the samples. In the ratio-on mode, the instrument uses multiple detectors at
different angles to correct for interferences and to increase the measurement range. In the ratio-off
mode, the instrument uses one detector at a 90-degree angle from the light source. The user can
calibrate the instrument and verify the calibration at regular intervals.
The user interface uses a touch screen display. A Seiko DPU-S445 printer, USB flash drive or
keyboard can connect to the USB ports. Refer to
