2.2 Overview of product
The LCM III is a color measuring instrument for determin the color
values of transparent, optically clear liquids. The instrument comes
with a complete set of application programs and multi-language
support.

Section 3 Installation
WARNING
Electrical and Fire Hazards. Use only the provided power
supply. Only qualified personnel should conduct the tasks
described in this section of the manual.
3.1 Unpack the instrument
The LCM III comes packaged with the following items:
•LCM III
•Dust cover
•External power supply, including 4 adapter for EU, UK, USA
and AUS/China
•cuvette/cell adapter Z
•LCM III user manual
Note: If any of these items are missing or damaged, contact the
manufacturer or a sales representative immediatly.
3.2 Environment considerations
The following conditions are necessary to make sure correct
instrument operation and accurate results:
•Place the instrument firmly on an even surface. Do not push
any objects under the instrument.
•Maintain an ambient temperature of 10 to 40 ºC (50 to 104 ºF)
for proper instrument operation.
•The relative humidity should be less than 80 %; moisture
should not condense on the instrument.
•Leave at least a 15 cm (6 in.) clearance at the top and on all
sides for air circulation to avoid overheating of electrical parts.
•Do not operate or store the instrument in extremely dusty,
damp or wet locations.
•Keep the surface of the instrument, the cell compartment and
all accessories clean and dry at all times. Splashes or spills on
and in the instrument should be cleaned up immediately (see
section 7.1 on page 47).
•After a continuous operating time of more than 24 hour without
switching off the instrument we recommend to perform a new
calibration with a distilled water cuvette/sample cell.
•After a continuous operating time of more than 7 days without
switching off the instrument we recommend to switch off and on
the instrument to perform a new system check with filter
adjustment and lambda-calibration.
Important Note: Protect the instrument from temperature
extremes, including heaters, direct sunlight and other heat sources.

Installation
3.3 Power connections
Install the correct adapter plug on the supplied external power
supply (Figure 1). Slide the adapter on until it "clicks" into position.
Correctly mounted, both housing of power supply and plug are in
line. Plug the external power supply cord into the connector on the
back panel of the instrument, then plug the supply into a power
outlet (100–240 V~ / 50–60 Hz). Press the power switch on the
back of the instrument to initialize power (Figure 2 on page 9).

Installation
3.4 Connection
The LCM III has two USB interfaces as a standard feature, located
on the back of the instrument (Figure 2).
The USB Type A interface is used for communications with a
printer, USB memory stick or keyboard. A USB memory stick is
used to update instrument software.
The USB Type B interface is used for communications with a PC.
The optional Data Trans 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 3 meters (10 feet).
These USB interfaces enable data and graphics to be output to a
Printer and a PC and upgrade instrument software (see
section 6.1.2 on page 38).

Installation
3.5 Cell compartments and cell adapter
3.5.1 Cell compartments and adapter
The LCM III has two cell compartments (Figure 3). Only one
cuvette/sample cell type at a time can be used for a measurement.
Cell compartment #1
•11-mm round cuvettes/sample cells
For measurements with 11 mm round cuvettes/sample cells in
cell compartment #1 insert the adapter Z into cell
compartment #2.
Cell compartment #2
Cell compartment #2 uses adapters to accommodate different
cuvette/sample cell types.
•50 mm rectangular cuvettes/sample cells (can be inserted
directly into the cell compartment without using an adapter).
•10 mm square cuvettes/sample cells (can be inserted with the
adapter Z)
Important Note: Be sure that the adapter Z is inserted proper into
the cell compartment. Press the adapter down until it snap into the
compartment.

Installation
3.5.2 Installation of the cell adapter
1. Open the cell compartment.
2. Insert the adapter for measurements with the round
cuvette/sample cell (11 mm) and/or 10 mm square
cuvette/sample cell so the arrow on top of the adapter points to
the left (Figure 4) and the orientation tab fits the groove in the
compartment opening.
Note: The arrow on top of the adapter indicates the direction of the light
beam path.

Section 4 Start Up
4.1 Power the instrument on and off
1. Plug in to the power supply (laboratory analysis) or insert the
battery (field analysis).
2. The push-button switch on the back of the instrument switches
the instrument on (press for about 1 second) and off (press for
about 3 to 5 seconds). An acoustic signal confirms that the
instrument has been switched off.
Note: Do not turn the instrument off and on in rapid succession. Always
wait about 20 seconds before turning the instrument on again, otherwise
the electronic and mechanical systems will be damaged.
4.2 Language selection
The LCM III software includes several language options. The first
time the instrument is turned on, the language selection screen will
appear.
1. Select the desired language.
2. Press OK to confirm. The self-check will start automatically.
Changing the language setting
The instrument functions in the selected language until the option is
changed.
1. While turning the instrument on, touch the screen at any point
until the list for selecting a language appears (about
30 seconds).
2. Select the required language.
3. Press OK to confirm. The self-check will start automatically.
4.3 Self-Check
Each time the instrument is powered, a series of diagnostic tests
are performed automatically to make sure operation of major
system components.
This procedure, which takes approximately two minutes, checks the
system, lamp, filter adjustment, wavelength calibration and voltage.
Each test which functions correctly is confirmed with a check mark.
Note: For further error messages during self-check, see Section 8 on page
55.

14
Start Up
The Color Measurement Menu is displayed when diagnostics are
completed. Insert a cuvette/sample cell with distilled water to
calibrate.The calibration starts automatically when the LCM III
recognizes a 11 mm round vial in the cell compartment #1. For the
use of square cuvettes/sample cells in the cell compartment #2,
press Start to start the calibration.
Insert the sample cuvette/cell. For the use of 11 mm round vials the
measurement starts automatically. For the use of square
cuvettes/sample cells in the cell compartment #2, press Measure to
start the measurement.
See section 5.1.3 Main Menu on page 16 for a detailed description.
4.4 Characteristics in continuous operation
After a continuous operating time of more than 24 hour without
switching off the instrument we recommend to perform a new
calibration with a distilled water cuvette/sample cell.
After a continuous operating time of more than 7 days without
switching off the instrument we recommend to switch off and on the
instrument to perform a new system check with filter adjustment
and lambda-calibration.
