Power

The colorimeter is powered by dedicated power adapter or special lithium batteries, the use of other facilities for power supply may damage the device. Ensure that the Switch is on Out (O) before connecting to the power adapter or mounting the battery.

Battery

  1. First, check and confirm if the Switch is on Out (O), then follow the arrow direction as shown in Figure 5, take out the battery cover by pressing down.
  2. Mount the battery into the compartment as shown in Figure 6, pay attention to the front and back of the battery.
  3. Follow the directions in Figure 7, press up to mount the battery into the compartment.

Power Adapter

  1. First, check and confirm if the Switch is on Out (O).
  2. Plug the input cable of the power as shown in the figure into the DC connector.

Interface

 Layout

 There are three parts of the colorimeter interface as shown in Figure 9, Page on top, Form on middle and Information on the bottom.

Page Details

Operation

 Turn on

Before turning on the instrument, check if the external power has been connected or the battery has been mounted, ensuring a power supply to the instrument, then start the instrument, the screen will show starting Logo. After the completion of boot interface, the instrument into the self-test program, ensure the normal working of the instrument.

Color Difference Measurement

There are two steps for the color difference measurement which are “Type Sample Measurement” and “Sample Measurement”.

  1. The Type Sample measurement gets the standard color parameters of a Type Sample.
  2. The Sample measurement gets the parameters of the sample needed to be measured while calculating the color difference data between the Sample and the Type Sample.

Type Sample Measurement

As shown in Figure 15, the Type Sample measurement can be performed to get the color parameters of a Type Sample. The color parameters measured will be shown on the measurement page.

In the upper right corner of the page, the test current conditions, including light sources, lighting and light mode, are displayed.

Sample Measurement

After completing the Type Sample measurement, if it is required to measure the color difference between the Type Sample and the Sample, press “Paging”   to switch the screen to “Sample Measurement” page as shown in Figure 16, the color difference parameter measured will be shown on the measurement page.

Meanwhile, the color bias will be shown on the right of the page to provide an intuitive color difference analysis.

Check out Information

 Type Sample Record

Press “Paging”  to jump to “Check out Information” page as shown in Figure 17 to check the saved data and to select from the drop-down menu by “Confirm”   as well as “Up”  and “Down”  keys if required.

In the current page, press “save”  button. In the below Figure  dialog box, choose “sample into” or “standard delete” operation.

Sample Record

After selecting the Type Sample to be checked, select “Sample Record” option to switch the screen to the Sample record page of the Type Sample as shown in Figure 18, then select Sample record by “Confirm”  as well as “Up”  and “Down”   keys to check out the color difference records of each Sample.

System Setting

Press “Paging”  to switch the screen to “System Setting” page as shown in Figure 19 to set the data saving ways as well as light mode, Light source (D50, D65, F11), tolerance, backlight time, the system date and time during the measurement.

Auto Save

There are two ways for saving the records .”Auto Save” and “Manual Save”.

When setting to Auto Save, the system will auto save each time measurement data of the Type Sample or the Sample. If the saving records of the Type Sample or the Sample are full, the measurement data will not be saved and will pop up a window as shown in Figure 20 to prompt if the storage should be cleared.

Manual Save

When setting to Manual Save, the system will not auto save data, it is required, after finishing measuring, to press “Save”  for manually saving the data and will pop up a prompt box as shown in the Figure.

SCI/SCE

The SCI is a measurement, including specular objects reflect light.
The SCE is a measurement, not including specular objects reflect light.

Source Selection
There are three kinds of the colorimeter standard light source to choose to measure, namely D50 (a relatively warm light and is used for prints and photographs daylight), D65 (average sunlight), F11 (a cold white light with low energy consumption and better color rendering color is specified in many European fashion industry standard light).
