2 Working principle
Tristimulus principle: The lightsource is reflected at the surface of the object and the colour sensor
receives the reflected light. After the digitalisation of the sensor data, the colour coordinates are
calculated and can then be used to determine colour deviations between the standard and the
sample. To do so, use the colour difference formula below.
Colour difference formula:
∆𝐸∗=√(∆𝐿∗)² − (∆𝑎∗)² − (∆𝑏∗)²
△E* = the total colour difference
△L = L*standard - L*samples △L+ = more white △L- = more dark
△a = a*standard - a*samples △a+ = more red △a-= more green
△b = b*standard - b*samples △b+ = more yellow △b- = more blue
Classification of colour difference ranges
△E
Classification
0 … 0.5
Minor difference
0.5 … 1.0
Small to medium difference, acceptable in some applications
1.0 … 2.0
Medium difference, acceptable in some applications
2.0 … 4.0
Large difference, acceptable for specific applications
4.0
Very large difference, unacceptable
Explanation: Colour differences are classified differently depending on the industry. Please
familiarise with the industry-specific requirements.

5.2 Calibration
When your instrument is first turned on, you should perform a calibration. Thereafter, a calibration
is required every hour or if a 5 °C temperature change has occurred. Calibration of the instrument
ensures optimum colour matching performance.
1. Move the white reference slider to the closed/calibration position over the optics.
2. Power on the instrument, then go the “Calibration” menu (left button –down button until
cursor is on “Calibration” – confirm with MEAS/ENTER). The display will show the
following:
3. Use the arrow keys to select “StandWhite” and press MEAS to initiate the calibration.
4. Open the optics and align the measuring aperture in the air without aligning it directly
with a light source. Go to the “Calibration” menu and select “StandZero”. Then press
the MEAS key to carry out the calibration.
5. If the calibration was successful, StandWhite“ or „StandZero“ will be ticked. If not, there
will be an “X” instead.
6. Make sure to always reposition the slider back to “Measure” location (optics opened)
before making a measurement.
Note: The calibration reference is dramatically affected by smudge marks and dust and must be
kept clean. It is recommended that the instrument is cleaned regularly.

5.3 Comparative measurement
Power on the instrument, initiate a calibration and then do measurement on selected standard
sample (Select standard from main menu –Standard or use your own standard). Press button
MEAS or MEAS/ENTER to measure and get the measurement result as shown in photo 1. If the
measurement has already been made or if the measuring time was too short, an error message
will appear. The result will be shown as in photo 1. When the value has stabilised, press right
button to view more results as in photo 2. Then measure your desired sample by pressing MEAS
or MEAS/ENTER.
S = standard measurement value
B = sample reading
△E = overall colour difference
The meter will then compare the test results and either show “Pass” (photo 2.1, high conformity)
or “Fail” (photo 2.2, low conformity).
The three mentioned values will be saved to the memory automatically.

5.4 Checking XYZ, RGB, CMYK and Pantone values
After a measurement, when the display looks as in photo 1, press the up or down key to check
the XYZ, RGB, CMYK or Pantone value (as shown in photo 2).

To save energy, you can set a time after which the display backlight or the device itself switches
off automatically. When you are in the main menu, use the up and down keys to select “Settings”
and confirm with the MEAS/ENTER key. Then select “MeterSetup” with the arrow keys and
confirm with MEAS/ENTER again get to the respective submenus.
These submenus SreenOff and PowerOff can be opened with the MEAS/ENTER key. Changes
can be made by using the up and down keys and confirmed with MEAS/ENTER.
The following can be selected:
SreenOff: 1 … 99 seconds
PowerOff: Off (No), 10, 20, 30 minutes
6.4 Set number of measurements for average calculation
In the “Settings” menu, select “MeasSetup” with the up and down keys and confirm with
MEAS/ENTER. Go to the menu item “AverTime” by using the up and down keys and press

average calculation with the up and down keys and confirm with MEAS/ENTER.
6.5 Set tolerance
In the “Settings” menu, select “MeasSetup” with the up and down keys and confirm with
MEAS/ENTER. Go to the menu item “DeSeting” by using the up and down keys and press
MEAS/ENTER. Now set the desired tolerance with the up and down keys and confirm with
MEAS/ENTER. A tolerance of 1.0 is preset.
6.6 Set colour formula
In the “Settings” menu, select “MeasSetup” with the up and down keys and confirm with
MEAS/ENTER. Go to the menu item “Delta-E” with the down key and press MEAS/ENTER. Now

6.7 USB connection
Connect the meter to your computer by using the Micro USB cable. The colour meter is
recognised as a HID device and all drivers will be installed automatically. When the installation is
completed, the PCE-XXM 20 will be recognised as follows:
Download the PC software from the following link:
https://www.pce-instruments.com/english/download-win_4.htm
Install and start the software. Further instructions can be found in the help file of the software.
Note:
The meter can only connect to the software if the USB icon is shown in the upper left part of the
display.
6.8 Bluetooth connection
Connect the instrument to smartphone via Bluetooth to transfer the measuring data to the Android
or iOs app.
7 Memory
The colour meter has memory capacity for up to 20 groups of data (S = standard measurement
value, B = sample reading, DE = overall colour difference) which are saved automatically after a
comparative measurement. In order to read out the memory, go to the menu item “DataLog” in
the main menu and confirm with the MEAS/ENTER key. To view a group of data, select it by
means of the up and down keys and confirm your selection with MEAS/ENTER. With the arrow
right key, youcan delete the selected individual group of data. To delete all groups of data, select
“Delete All” from the overview and confirm with MEAS/ENTER.
Note:
When clearing the complete memory, you will not be asked to confirm that you wish to delete all
data.
8 Charging the battery
Before using the colorimeter for the first time, it is important that you fully charge the battery.
Otherwise, the internal lithium-ion battery may experience a shortened life.

The meter can be charged when switched off or when switched on. However, operation during
charging is not possible. Connect the supplied USB cable or a USB cable of the same type to the
colour meter and to your computer's USB port. If the meter is on, you will see this icon when
the meter is charging. A full charge of a completely empty battery will take approx. 6 hours.
Battery icon information

half charged - sufficient for a substantial number of measurements
low - measurements still possible but battery should be charged soon
charging.
9 Troubleshooting
Variables that may affect the measuring results and should be avoided include:
- Sensor blocked
- Environmental temperature too low –slow display reaction, limited accuracy
- Improper use of the instrument or unsuitable sample:
•The instrument does not lie flat on the sample.
•The sample has an uneven texture.
•The sample is dirty.
•The sample contains fluorescent, metallic, or pearlescent colorants.
•The sample looks different when viewed at different angles.

11 Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
