2.4 Measurement
Measurement is divided into standard measurement and sample measurement.
The standard measurement is to measure the chromaticity data of standard sample, while sample measurement
is to measure the color different or contrast chroma data between standard sample and target sample.
After turning on the the instrument and finishing the white and black calibration, it is ok to do the standard
measurement and sample measurement (the users can set the corresponding color space and color index in the
main menu interface as required (please refer to Chapter 3 for details), and the system default setting is CIE lab
color space, ΔE * ab color formula, and the color index is empty). If it is not currently in the measurement interface,
continuously click the return key several times in the interface or tap the "testing key" to return to the
measurement interface.
2.4.1 Standard Measurement
In the “Standard Measurement” interface, Align the measuring aperture of the instrument to the tested sample
and press the “Testing key” tightly. Then there is a “Beep” voice, and the LED indication light will go from flashing
to off. After that, a “Beep” voice will come again, and it means measurement finished as shown in Figure 9
and in Figure 10.
Detail instructions of standard measurement interface are as following:

1) Interface Title: Indicating it is under interface of standard measurement.
2) Condition area: display system setting such as illumination,UV (on/off), Bluetooth (on/off), measurement mode
and the current time, date and power etc. Only when turn on Bluetooth or UV function, they will be highlighted.
3) Camera Locating: Click to use the camera to position the measurement, then press “Testing” key to complete
measurement.

2.3.3 Sample Measurement
After testing the standard, click “Sample measurement” to enter Sample Measurement interface. It is the same
steps with standard measurement. After measurement, it will display as shown in Figure 11 and in Figure 12.
Sample measurement is similar with standard measurement but it will display the color difference between the
current standard and measured sample.
Detail instructions of sample measurement are as following:
1) Interface Title: Indicating it is under interface of sample measurement.
2) Standard Name: Display the current measurement standard name, and all sample chromatic data is based on
the current standard.
3) Sample Name: Display the current measurement sample name, and click it to quickly modify, or the default is
No name.
4) Display mode: Click “SCI/SCE” to refresh the current measurement data in real time.
Note: The SCI and SCE of the display mode is the same as those of the standard measurement.
5) Sample Chromatic Data: Display the current chromatic data.
6) Delta E (Color Difference): The color difference between standard and sample.
7) Measurement Result: Display the test result under the color formula and tolerance. If the result is larger than
the tolerance value, it will show red “Failure”, or show green “Pass”. This function only exists when you turn on the
function of “Display Measurement Result” in the system setting.
8) Color Offset: Color deviation of the current sample compared with standard. It only displays color offset when
you turn on the function in the system setting.
