What effect does the holding time of a microhardness tester have on the test results?

Dwell time is a very important parameter in microhardness tester testing. A dwell time that is too short may lead to higher test results, while a dwell time that is too long may cause lower test results. Therefore, when setting the dwell time of the microhardness tester, we need to make a selection based on the material and hardness range of the sample to ensure the accuracy of the test results. Chung-Tse's microhardness tester has an adjustable dwell time function, which can be set according to needs, making it very convenient and practical.
