EMC: Supporting test records with Dash Straus and Goodhue, Inc.
(now Intertek Testing Services), certified compliance by
Hach Company.
Standards include:
IEC 801-2 Electro-Static Discharge
IEC 801-3 Radiated RF Electro-Magnetic Fields
IEC 801-4 Electrical Fast Transients/Burst
Emissions
2100P Turbidimeter Tested with external Battery/Eliminator

CERTIFICATION, continued
FCC Part 15, Class “A” Limits: Supporting test records by Amador
Corp. (now TUV Product Services), certified compliance by
Hach Company.
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
1. this device may not cause harmful interference, and
2. this device must accept any interference received, including
interference that may cause undesired operation.
Changes or modifications to this unit 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 may
cause harmful interference in which case the user will be required to
correct the interference at his own expense.
The following techniques of reducing interference problems are
applied easily:
1. Disconnect the battery eliminator from it’s power source and
from the 2100P Portable Turbidimeter to verify if it is the source
of the interference
2. If the battery eliminator for the 2100P Portable Turbidimeter is
plugged into the same outlet as the device with which it is
interfering, try another outlet.
3. Move the 2100P Portable Turbidimeter away from the device
receiving the interference.
4. Reposition the receiving antenna for the device receiving
the interference.
5. Try combinations of the above.

To ensure the protection provided by this equipment is not impaired, do
not use or install this equipment in any manner other than that which is
specified in this manual.
Use of Hazard Information
If multiple hazards exist, this manual will use the signal word (Danger,
Caution, Note) corresponding to the greatest hazard.
DANGER
Indicates a potentially or imminently hazardous situation which,
if not avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that may result in minor
or moderate injury.
NOTE
Information that requires special emphasis.
Precautionary Labels
