What should I do if the results measured by the colorimeter are abnormal

Performance configuration of colorimeter:

1. “You need to know which colorimeter is suitable for your industry, and the requirements for color difference accuracy are different for each industry, that is, △ Eab. If △ Eab is between 0-1, you must choose an instrument with higher accuracy;”; These are generally rubber and plastic, paint and paint industries; If you do not need a relatively high accuracy, you can also choose a general color difference instrument.

2. You need to understand the shape of your product. Currently, the test aperture of the general color difference instrument is 4mm or 8mm; If your product has a curved surface or is very small in size, it is necessary to consider the issue of the test aperture; Of course, it can also be customized, such as:

Large aperture (LAV): 2.54 cm (1 inch)
Medium aperture (MAV): 1.5 cm (0.6 inches)
Small aperture (SAV): 0.75 cm x 1.0 cm (0.3 inches x 0.4 inches)
Ultra Small Aperture (VSAV): 0.3 cm x 0.8 cm (0.12 inches x 0.31 inches)

3. Is there a national metrological certification. This type of instrument is a metrological instrument. It is important to understand whether the product can meet national metrological requirements, otherwise there will be disputes, and your data will not be available for reference.

In general, for a color difference instrument that is worth purchasing, there are many factors worth considering in addition to the main factors mentioned above.

What should I do if the results measured by thecolorimeter are abnormal?

1. This situation is generally caused by the lack of black and white correction or inaccurate black and white correction, which requires a black and white board correction first. Dirt entering the measuring port can also cause inaccurate measurement. It is best to check before measuring;
2. Check whether the battery consumption is too low (below 20%), replace it with a new dry battery or use a DC power supply;

3. Check whether the instrument and test object are stable during measurement, and whether the contact between the measurement port and the measurement surface is tight and good;
4. Check whether the measured object is too thin and leaks light;
5. Check whether the measured part is mixed with colors; If the measurement results are still zero after the black and white board correction, it can be determined that the instrument is broken.

What should I pay attention to when using a colorimeter?

1. This instrument is a precision measuring instrument. During measurement, it is necessary to avoid drastic changes in the external environment of the instrument, such as flickering of ambient light during measurement.
2. This instrument is not waterproof and cannot be used in high humidity environments or water mist.
3. Keep the instrument clean and avoid liquid, powder, or solid foreign matters such as water, dust, entering the measuring aperture and the inside of the instrument. Avoid collision and collision with the instrument.

4. If the instrument is not used for a long time, the battery should be removed.
5. Do not use a power adapter other than our company’s dedicated power adapter, otherwise it may cause the instrument to burn down.
6. After using the instrument, put the color difference meter and white board cover into the instrument box and keep them properly.
7. The instrument should be stored in a dry, cool and environment. To avoid damage to the instrument.
