Class A:
Supporting test records by Intellistor OATS, certified compliance by Hach.
This Class A digital apparatus meets all requirements of the Canadian
Interference-Causing Equipment Regulations.
Cet appareil numérique de la classe A respecte toutes les exigences du
Règlement sur le matériel brouilleur du Canada."
FCC Part 15Class “A” Limits: Supporting test records by Intellistor
OATS, 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
(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 is
likely to 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 power from the DR2010 instrument to verify that is the
source of the interference.
2. If the DR/2010 Instrument is plugged into the same outlet as the
device with which it is interfering, try another outlet.
3. Move the DR/2010 away from the device receiving the interference.
4. Reposition the receiving antenna of the device receiving the
interference.
5. Try combinations of the above.

SECTION 1 GENERAL DESCRIPTION
1.1 Instrument Description
The Hach Model DR/2010 Spectrophotometer shown in Figure 1 is a
microprocessor-controlled, single-beam instrument for colorimetric
testing in the laboratory or the field. The instrument is precalibrated for
over 120 different colorimetric measurements and allows convenient
calibrations for user-entered and future Hach methods.
Instrument features include:
•Test results displayed in percent transmittance, absorbance
or concentration.
•Data Storage and Recall for datalogging in the field or laboratory.
•Operator-selected languages.
•Full prompting during testing.
•Error messages for procedural or instrument troubleshooting.
•A built-in timer to monitor specific reaction times called for in the test
procedures. The appropriate time intervals are stored in the program
for that test. The timer also can be used manually by the operator
independent of the stored programs.
•RS232 interface capability allows an external printer or computer to
interface with the spectrophotometer. This makes software upgrades
easy to do with a computer and software disk from Hach.
•Simplified entry of user-entered programs or new Hach methods.
The spectrophotometer operates on battery power or ac line power using
the battery eliminator/charger unit supplied with the accessories. The
battery holder supplied holds six D-size alkaline dry cells (batteries not
supplied) that power the instrument for approximately 100 tests. An
optional rechargeable lead-acid battery is available, and can be recharged
with the battery eliminator/charger supplied with the instrument. The
eliminator/charger will not charge rechargeable D-size batteries.

16
CAUTION
Do not use or store
the lead-acid
battery above 60 °C
or the battery may
leak. Use D-cell
batteries instead.
CUIDADO
No utilizar o almacenar la bateria de ácido de plomo a una temperatura supérior a
60 °C ya que esto puede producir un excape en la bateria. Utilizar en su lugar una
bateria de pila seca.
CUIDADO
Não utilize nem armazene a bateria de ácido-chumbo em temperaturas superiores a
60 °C, pois podem ocorrer vazamentos. Use, ao invés disso, baterias secas tipo D.
PRUDENCE
Ne pas utiliser ou stocker la batterie plomb-acide au-dessus de 60 °C, sinon la batterie
rique de fuir. Utiliser les piles taille D.
WARNHINWEIS
Der Bleiakkumulator darf nicht über 60 °C benutzt oder gelagert werden, da er sonst
auslaufen kann. Benutzen Sie alternativ die D-Zellen.

SECTION 2 INSTRUMENT/ACCESSORY SETUP
2.1 Unpacking Remove the instrument and all accessories from the shipping container
and inspect each item for any damage that may have occurred due to
rough handling or extreme weather conditions during shipment. Verify
that the items listed in section 1.2 Accessories are included. If any items
are missing or damaged, please contact Hach Customer Service,
Loveland, Colorado for instructions. The toll-free number is 1-800-227-
4224. For customers outside the United States, contact the Hach office or
distributor serving you.
2.2 Supplying Operating Power
2.2.1 Battery Eliminator/Charger
If line power is used, connect the battery eliminator/charger (power
supply) cable plug to the POWER connector on the back of the
instrument, and plug eliminator/charger power cord into the power
receptacle (see Figure 11).
Note: For safety
and performance
never operate the
DR/2010 without
the battery and
lamp covers
closed.
When the battery eliminator/charger is connected and operating, the
instrument operates on line power only and the battery will not power the
instrument. If the optional rechargeable battery is installed, the instrument
will operate and the battery will be charged simultaneously.
This power supply will operate on line voltages from 95 Vac to 240 Vac.
Power supply voltage selection is automatic, no user interaction is
required.
2.3 Assembling the Pour-Thru Cell
The 1-inch and 1-cm Pour-Thru sample cells are optional accessories
that improve convenience and accuracy, especially when measuring very
low concentrations. Because the same optical characteristics exist for
both zeroing and measuring, or when comparing measurements of
different samples, any error resulting from optical differences between
individual sample cells is eliminated. Rapid Liquid methods speed
analysis and require use of the Pour-Thru Cell (see the procedure
manual for these programs).
The optional Pour-Thru Cell Assembly must be assembled and installed
before use. Figure 2 illustrates the assembled unit.
