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 2100AN laboratory turbidimeter measures turbidity in NTUs
(nephelometric turbidity units), NEPs (nephelos) and EBCs (European
Brewing Convention units). NEPs and EBCs are calculated using the
conversion factors of 6.7 nephelos per 1.0 NTU and 0.245 EBCs per
1.0 NTU. The 2100AN turbidimeter also measures absorbance,
transmittance and color (APHA Pt-Co Method).
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).
