New strides in technology have transformed the surface Roughness tester from a chunky three-piece equipment that had to be pushed around on a cart into a sleek, portable gadget. Today’s surface gauges are much more affordable next to the tens of thousands of dollars pioneering models cost, and they can do it all as well. However, there are some things you can take note of to optimize the use of your portable surface gauge – let us spell them out for you below.
Ensure the roughness gage is Functioning Properly Before Use
You should always check that a roughness gage is functioning properly before use with the help of a separate test patch or test specimen. Some gauges have a built-in test specimen that you can use to check your gauge by moving the probe over to it and making a trace. Alternatively, you can use a test patch; however, these are not easy to obtain as they are kept under lock and key due to the traceability of the specimens.
Check the Settings for the Parameter
Most roughness gages come with a feature allowing you to select the number of cutoffs, length of cutoffs, traverse speed and more. Make sure that these settings correspond with the test conditions required for your inspection process.
Check the Surface Test Environment
The results of surface roughness measurements can be affected by environmental conditions such as the presence of dirt and oil. In order to get the most accurate measurement and protect your gauge, always make sure that the environment is free from oils, dirt and burrs. Next, always make sure that the area is undisturbed from loud sounds and vibrations that can significantly alter measurements. This can come from a passing truck or even a radio that has the volume on too high.
Check that Results Make Sense and Save For Future Review
Always keep a reference patch nearby so that you are able to tell immediately if the measurements are not coming in the right denominations. That’s when you know there is something wrong with the roughness gage or probe that needs to be addressed before proceeding.
After the measuring process is completed, make sure to save your results for easy reference and analysis. Most gauges on the market today come with internal storage, making it incredibly convenient to store data with just one click.
