Section 3 Installation
WARNING
Electrical and Fire Hazards. Use only the provided power
supply. Only qualified personn el 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
• 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 resu lts:
• Place the instrument firmly on an even surface. Do not push
and AUS/China
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 an d 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 (
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 (

3.4 Connection
Installation
The LCM III has two USB interfaces as a standard feature, located
on the back of the instrument (
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.

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.
4.3 Self-Check
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.
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 volt age.
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.
13
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 of f and on the
instrument to perform a new system check with filter adjustment
and lambda-calibration.

5.4 Sampling and sample preparation
Take a representative sample from the product you want to
measure in accordance with DIN EN ISO 15528 (or ASTM
D3925-02).
If the material shows any visual haziness, remove the haze by
either filtration, centrifugation, heating, ultrasonic treatment or
suitable means.
Heat partly solid samples before measuring in order to dissolve the
solid material in the liquid. The preparation must not cause any
chemical changes in the sample.
Make sure that during the measurement are no bubbles in the
sample.
There are three cuvette/sample cell types available for color
measurement with the LCM III, differing by material (glass, PS and
PMMA) and path length (10 mm,11 mm and 50 mm). Fill the
cuvette/sample cell to approximately 2 cm. The light beam passes
through the cuvette/sample cell around 0.5 cm to 1.5 cm above the
base of the cuvette/sample cell.
The program calculates and displays Iodine, Hazen, Gardner,
Saybolt, Klett and ASTM D 1500 color values automatically, taking
into account the cuvette/sample cell type.
Standard Operations
A dry thermostat is available for the 11 mm disposable round glass
cuvettes/sample cells. The dry thermostat heats the
cuvettes/sample cells to any temperatur e be tween ambiant and
150 °C.
Important Note: The samples must be clear and free of turbidities.
If products in paste or solid form cannot be measured directly, the
product must be melted before being transferred to the
cuvettes/sample cells. Make sure the cuvettes/sample cells do not
contain any air bubbles.
• Always hold the cuvette/sample cell close to the top, to make
sure that there are no fingerprints in the measurement zo ne of
the cuvette/sample cell. Use suitable transfer pipettes to
introduce samples into the cuvettes/sample cells.
• Slowly add samples to the cuvettes/sample cells cells to make
sure air bubbles do not form on the cuvette/sample cell wall
and in the sample. Air bubbles will cause false readings.
• If air bubbles are entrapped, remove them by heat, vacuum,
ultrasonic treatment or other suitable means.
• Clean the outside of the cuvettes/sample cells thoroughly
before inserting them in the cell compartment.
Important Note: Before using disposable cuvettes/sample cells
made by PS (Polystyrene) or PMMA (Polymethyl methacrylate) be
sure that the cuvettes/sample cells will not be destroyed by
samples, otherwise the cell compartment can be damaged.
