Turn on and set up the digital radius gauge. (Dependant on your product instructions). Note: some digital gauges require an external computer system to process the data.
Step 2 – Select application
Consider your application. A digital radius gauge is capable of measuring inside diameters of cylindrical holes, measuring grooves and measuring diameters of spheres from 100mm to 1000mm.
Step 3 – Position gauge
Ensure the centre strip is pressed against the test piece and the scale slider is moved up or down until the strip contacts meet the test piece. The gauge is able to extend significantly to meet the surface.
Step 4 – Read measurement
After the contact points are left in contact with the radius for a few seconds then an exact radius measurement may be read from the digital display.
You may wish to look at the versatility of the gauge beyond measuring sheet metal. Further applications are listed below:
A digital gauge can be used to measure the waviness on a finished surface.
A digital gauge can be used to measure the radius of a television tube.
A digital gauge can be used to measure the radius of a mould.
It can also be used to measure the radius of wood or art products.
A digital radius gauge can be used to measure the radius of machine bent pipe.
Or it can be used to measure the changing radius during roll forming.
