2.2 Overview of product
The K13560 and K13270 instruments are VIS
spectral-photometers with wavelength ranges from 320 to
1100 nm. The instruments can perform a precise colorimetric
analysis in accordance with ISO/ASTM standards with a single
measurement and display the result in the form of classic color
systems such as iodine, Hazen or Gardner color values. The
instruments support multiple languages.
The K13560 is supplied with 26 color value calculations, while
the K13270 is supplied with five colo
r value calculations (Iodine
color, Hazen color, Gardner color, Saybolt
color and ASTM D
1500 color numbers).
WARNING
The manufacturer is not responsible for any damages due to
misapplication or misuse of this product including, without limitation,
direct, incidental and consequential damages, and totally excludes
such damages as permitted under applicable laws.
The user is solely responsible to identify critical application risks and
install appropriate mechanisms to protect processes during a possible
equipment malfunction.
CAUTION
Burn hazard. Allow the lamp(s) to cool for at least 30 minutes before
maintaining/replacing them.
DANGER
Potential danger with contact with chemical/biological substances.
Working with chemical samples, standards and reagents can be
dangerous.
Make yourself familiar with the necessary safety procedures and the
correct handling of the chemicals before use and read and follow all
relevant safety data sheets.
11
General Information
The K13560 contains the following programs and operating
modes in addition to the color measurement: single wavelength
mode, multi-wavelength mode, wavelength scan and time scan
mode. The digital measurements are displayed in the
dimensional units of concentration, absorbance or %
transmittance, making the K13560 universally suitable for lab
analysis.

Note: If any of these items are missing or damaged, please contact the
manufacturer or a sales representative immediately.
3.2 Operating environment
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).
• 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.

Installation
3.5 Interfaces
The instrument has three USB ports and one Ethernet port as
standard. They are located on the front and rear of the instrument
(Figure 1 Figure 2, page 15).
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 Lange Online Data software must be installed on
the PC for this use.
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 6.1.2, page 87). 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 Cuvette compartments and cuvette adapters
3.6.1 Cuvette compartments and adapter
Open the cuvette compartments by sliding the cuvette
compartment cover to the left.
The cover lowers to the side next to the cuvette compartments.
Note: If there are long intervals between uses, close the cuvette
compartment cover to protect the optics of the instrument from dust and
impurities.
The instrument has two cuvette compartments (Figure 3). Only
one cell type at a time can be used for a reading.
Cell compartment (1) for:
• 11 mm round cuvettes
Note: Insert cuvette adapter Z into the cuvette compartment (2).
Table 1 Interfaces
Interfaces Description
USB (Type A) This USB port can be used to connect a printer, a USB memory stick or a keyboard.
USB (Type B)
This USB port is intended only for the connection between the instrument and a PC (when the
relevant software is installed).
Ethernet
The Ethernet port is intended for data transfer to a PC without installed software or in a local
network . Only use a shielded cable (e.g. STP, FTP, S/FTP) with a maximum length of 20 m for
the Ethernet port.
17
Installation
Cell compartment (2) for:
The following cell types can be used in cell compartment (2).
• Without cuvette adapter Z in the cuvette compartment (2),
you can insert 50 mm cuvettes.
• With cuvette adapter Z: 10 mm square cuvettes.
Note: These cuvettes must be inserted with cuvette adapter Z.
Note: In the event of severe contamination, you can replace the cuvette
compartment (2) (see chapter 7.3, page 100).
3.6.2 Installation of cuvette adapter Z
1. Open the cuvette compartment.
2. Insert cuvette adapter Z into the cuvette compartment (2) so

COLOR MEASUREMENT MODE is used to determine color values such as Hazen,
Gardner and Saybolt. The K13560 also offers three-dimensional, absolute
colorimetric values, as well as the color scales of CIE L*a*b*, Hunter Lab or the
European Pharmacopoeia.
Color difference measurement
(only K13560)
The mode for
COLOR DIFFERENCE MEASUREMENT is used to determine a
quantitative color difference between a reference (R) and a sample (P) in the
three-dimensional color space (CIE L*a*b* or Hunter Lab). In this mode, an additional
reference memory for up to 100 references is available.
Photometry
(only
K13560)
Single Wavelength
Single wavelength readings are:
Absorbance readings: The light absorbed by the sample is measured in absorbance
units.
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.
Multi Wavelength
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.
Time course
The time scan records the absorbance or % transmittance at a wavelength over a
defined time.
Wavelength Scan
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.
System Checks
The "System Check" menu contains a number of options, such as instrument
information, optical checks, instrument backup, service times, instrument update,
settings for analytical quality assurance and lamp history.
Recall measurement data
Saved data can be retrieved, filtered, sent to a printer, memory stick or PC and
deleted.
Instrument Setup
This menu is used to configure user-specific and/or process-specific settings:
operator ID, date and time, security settings, saved data, sound, PC and printer and
energy management.

Note: If a USB Barcode handset scanner (refer to section 5.2.2.1,
page 25) is connected, Sample IDs can also be scanned.
4. Press OK to confirm the entry.
5. Assign the current time and date, a sequential number or a
colour to the sample ID.

6. To number the sample IDs sequentially (e. g. Inflow (01) etc.),
press Add Number.
• Use the arrow keys to specify the first number of the
sequence.
• Use the key between the arrow keys to enter the first
number of the sequence using the alphanumeric keypad.
7. Press OK to return to the "Instrument Setup" menu.
The Sample ID is activated. Each Sample ID is automatically
numbered in ascending order after a reading. The number is
shown in parentheses behind the Sample ID.
8. Press Back to return the instrument to the "Instrument Setup"
menu.
Press Off to switch off the active sample ID.
Press Select to activate the selected sample ID.
Use Options to enter, change or delete additional sample
IDs. The following screen is displayed:
