1. Purpose.
The purpose of this procedure is to standardize the operation method of the clarity test card and ensure the accuracy and reliability of the test results.
2. Steps.
1.Preparation.
Before starting the test, make sure that the clarity test card is clean, free of scratches, stains, and has not suffered any physical damage. If necessary, use a soft, damp cloth to gently wipe the surface of the test card.
2.Set up a test environment.
Make sure that the test environment is moderately lit and free of strong reflections so that the test results can be observed. At the same time, ensure that the temperature and humidity of the test environment are appropriate to avoid environmental factors affecting the test results.
3.Procedure.
Place the clarity test card on a flat table and adjust the monitor to the correct angle so that the center of the monitor screen is aligned with the center of the test card. Make sure that the display brightness, contrast, and other parameters are set correctly.
4.Observe and document the results.
Look at the test card on the monitor and pay attention to the color and detail of each area. Based on the observations, the scores for each area are recorded on a record sheet. Please note that scoring should be based on actual observations and avoid guesswork or guesswork.
5.Repeat the test.
To ensure the accuracy of the test results, it is recommended to perform multiple tests on the same test card and record the results of each test. The average of multiple tests is taken as the final result to reduce the error.
6.Analysis of results.
Based on the recorded scoring results, the clarity performance of the display is analyzed and determined. If you notice clarity issues with your monitor, check your monitor settings and hardware status, and make any necessary adjustments or repairs.
3. Precautions.
1.When performing the test, make sure that the test card is placed flat to avoid inaccurate test results due to uneven placement.
2.When observing the monitor, please keep an appropriate distance to avoid getting too close or too far away to affect the observation results. It is recommended to set an appropriate viewing distance according to the size and resolution of the monitor.
3.When performing multiple tests, please keep the test environment stable to avoid changes in environmental factors (such as light, temperature, humidity) that affect the test results.
4.When recording results, make sure that the records are accurate and avoid recording errors that affect the final analysis results.
5.When analyzing the results, please make judgments based on the actual situation, and avoid relying too much on the test results and ignoring the influencing factors of the actual situation (such as display models, brand differences, etc.).
6.This operating procedure is only a guiding document, and the specific operation should be adjusted and improved according to the actual situation. If you have any questions or encounter special circumstances, please consult or ask for help from professional and technical personnel in time.
