• Dust cover
• USB dust cover, fitted as standard
• Benchtop power supply with power cord for EU
• Cell adapter A.
• Light shield, fitted as standard in the DR 3900
• Operator RFID tag (not available on all models)
3.2 Operating environment
• Basic operating instructions DR 3900, operating instructions
LINK2SC
Further information, detailed user manuals and documentation
are available on the website of the manufacturer.
Note: If any of these items are missing or damaged, please contact the
manufacturer or a sales representative immediately.
Observe the following points to allow the instrument to function
normally and give a long operating life.
• Position the instrument securely on a flat surface taking care
to remove any objects from under the device.
• The ambient temperature must be 10–40 °C (50–104 °F).
NOTICE
Protect the instrument from extreme temperatures from heaters,
direct sunlight and other heat sources.
• The relative humidity should be less than 80 %; moisture
should not condense on the instrument.
• Leave at least a 15 cm clearance at the top and on all sides
for air circulation to avoid overheating of electrical parts.
• Do not use or store the device in extremely dusty, humid or
wet places.
• Keep the surface of the instrument, the cell compartment and
all accessories clean and dry at all times. Immediately
remove splashes or spilt materials on or in the instrument
(refer to Section 7).

WARNING
Electrical and fire hazards.
Only use the supplied benchtop power supply LZV844.
1. Connect the power cable to the benchtop power supply.
2. Plug the benchtop power supply cable into the back of the
instrument (Figure 2, page 17).
3. Insert the power cable plug into a mains socket
(100–240 V~/50–60 Hz).
4. Turn on the power button next to the display to turn on the
power supply (Figure 1, page 16).
17
Installation
3.5 Interfaces
The DR 3900 features three USB ports and one Ethernet port as
standard, located on the front and rear sides of the instrument
(Figure 1 and Figure 2, page 17).
The USB type A ports are used for communications with a printer,
USB memory stick or keyboard. A USB memory stick can be
used to update the instrument software.
The USB type B port is used for communications with a PC. The
optional Hach Data Trans software (refer to Section 9, page 137)
must be installed on the PC for data transfer.
A USB hub may be used to connect several accessories at a
time.
Note: USB cables must not be longer than 3m.
These USB ports permit data to be exported to a printer or PC
and also allow the instrument software to be upgraded (refer to
section 6.8.2, page 111). The Ethernet port supports real-time
data transfer in local networks, LIMS systems or SC controllers.
Only use a shielded cable (e.g. STP, FTP, S/FTP) with a
maximum length of 20 m for the Ethernet port.
3.6 Cell compartments, cell adapters and light shield
3.6.1 Cell compartments and adapters
The DR 3900 has two cell compartments (Figure 3). Only one cell
type at a time can be used for a reading.
Cell compartment (1) for:
• 13 mm round cells
Note: Cell compartment (1) contains barcode detection for
cells.
Cell compartment (2) for:
The following cell types can be used in cell compartment (2).
• Without cell adapter A, 50-mm cells, 1-inch rectangular cells
and 1-inch flow cells can be used directly in cell compartment
(2).
• With cell adapter A: 10 mm rectangular cells, 1-inch round
cells and AccuVac® vials.
Note: These cells must be inserted using cell adapter A.

1. Open the cell compartment.
2. Place the cell adapter into cell compartment (2) so that the
arrow on the cell adapter points to the rear (Figure 5).
Note: The arrow on top of the cell adapter indicates the direction of
the light beam path.
3.6.3 Use of the light shield for measurements
The light shield (Figure 6) prevents disruptive exposure to light
when 13 mm round cells are used in the cell compartment (1).
Insert the light shield into cell compartment (2) before performing
measurements in cell compartment (1).
The instrument is shipped with the light shield installed. Remove
the light shield before using cell compartment (2).

with a fingernail, fingertip, an eraser or a specialised stylus. Do
not touch the screen with sharp objects, such as the tip of a
ballpoint pen.
• Do not place anything on top of the screen, to prevent
damage or scratches on the screen.
• Press buttons, words or icons to select them.
• Use scroll bars to move up and down long lists very quickly.
Press and hold the scroll bar, then move up or down to move
through the list.
• Highlight an item from a list by pressing it once. When the
item has been successfully selected, it will be displayed as
reversed text (light text on a dark background).
5.1.2 Use of the alphanumeric keypad
This display is used to enter letters, numbers and symbols as
needed when programming the instrument. Unavailable options
are disabled (grayed out). The icons on the right and left of the
screen are described in Table 1.
The central keypad changes to reflect the chosen entry mode.
Press a key repeatedly until the desired character appears on the
screen. A space can be entered by using the underscore on the
YZ_ key.
Press Cancel to cancel an entry, or press OK to confirm an entry.
Note: It is also possible to use a USB keyboard (with US keyboard
layout) or a hand-held USB barcode scanner (refer to Section 9,
page 137).

Transmittance reading (%): Measures the percent of the original light that passes through the
sample and reaches the detector.
Concentration readings: A concentration factor can be entered to enable the measured
absorbance values to be converted into concentration values.
In the Multi Wavelength mode, absorbance (Abs) or percentage transmittance (%T) is
measured at up to four wavelengths and absorbance differences and absorbance relationships
are calculated. Simple conversions into concentrations can also be carried out.
A wavelength scan shows how the light from a sample is absorbed over a defined wavelength
spectrum. This function can be used to determine the wavelength at which the maximum
absorbance value can be measured. The absorbance behavior is displayed graphically during
the scan.
The time scan records the absorbance or % transmittance at a wavelength over a defined
time.
The "System check" menu offers a number of options, including optical checks, output checks,
lamp history, instrument update, service time, settings for analytical quality assurance and
instrument backup.
In this mode, user-specific or method-specific settings can be entered: operator ID, sample ID,
date & time, sound, PC & printer, password, energy-saving mode and stored data.
