^ Test Element for the Register Measuring System LUCHS

Technical data

What is tested?	All measuring functions of the LUCHS; the compliance of the measured absolute values with the measuring uncertainty in the LUCHS Operating Manual, i.e. the metric length values in μm.
How?	You just click the test software and measure the test element by positioning the LUCHS measuring head ten times on the test element. The test is documented by a printed test protocol.
When?	The use of the test element for the checking of the LUCHS is principally left to the user of the LUCHS. The check could be carried out once every year or as part of the routine examination of the measuring equipment. The check is recommended after the change of the lamp in the measuring head or once every year.
