Proper use of precision measuring tools is one of the most important preconditions to ensure product quality. To maintain the accuracy and reliability of a precision measuring tool, one has to do a good job in taking good care of it besides using it properly according to reasonable operation instructions. Actually, the electrical measuring tools can do these. There are many things that one has to keep track off when it comes to any manufacturing process. Measurement is one such aspect that one has to take care of as it plays a very vital role in ensuring that you have complete control over the entire process.
Precision electrical measuring tools should not be used as substitutes for other tools. So it is not advisable to use vernier caliper as line markers, micrometers as small hammers or steel linear as screw drivers and cutting scrap wipers. It is not proper either to take precision measuring tools as toys, take flinging a micrometer with hands for example. These behaviors will lead to the falling of accuracy of precision measuring tools.
What’s more, temperature does have a substantial impact on the measuring results. Precise measurement of work pieces should be carried out only under the condition that the temperature is around 20oC. Generally, measurements can be carried out under room temperature, but the work pieces and the measuring tools should share the same temperature. Otherwise, the result of measurements will not be accurate due to the characteristic of distortion of metals subject to temperature changes.
Precision electrical measuring tools are subject to the changes of temperature, too. They should not be put under direct sunshine, because measurements will not be achieved when the temperature rises. Never put precision measuring tools near heat sources such as electric cooker and heat transmitter to protect the tools from being distorted by heat thus disabling accuracy.
Finally, periodic maintenances should be applied to precision measuring tools. Long-used precision tools should be sent to authorized calibration facilities periodically for test and calibration to avoid product quality problems caused by unreasonable reading errors of the tools.
