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
The DR 1900 is a portable VIS spectrophotometer that measures in the wavelength range of 340 to
800 nm. The instrument is used to measure various parameters in drinking water, wastewater and
industrial applications. For field use, the instrument operates on four AA batteries. The instrument
comes with a complete set of application programs: stored programs (pre-installed methods), LCK or
TNTplus methods, user programs, favorite programs, single wavelength, multi-wavelength and time
course modes. Refer to Figure 1.

Install the batteries
WARNING
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.
WARNING
Fire hazard. Battery type substitution is not permitted.
N O T I C E
Make sure to tighten the screws carefully for a correct seal fit. Do not over-tighten.
Use four AA alkaline or four rechargeable NiMH batteries to energize the instrument. Make sure that
the batteries are installed in the correct orientation. Refer to Figure 3 for the battery installation.
