3.3 Self-test (check)
When the instrument is switched on, and each time an evaluation mode is selected, the
LUMIStox 300 automatically performs a self-test.
In addition the correct functioning of the LUMIStox 300 can be checked with the options
shown below. The result of the check can be documented as a test report on a printer if
the final function to be checked is the printer connection, with <prn> (see below). Status
and error messages describe the current operational capability in accordance with ISO
9000 ff.
The self-check is no substitute for regular specialist maintenance of the instrument. You
should contact Dr. Lange Service in Germany (++49/(0)211-5288-0) for all matters
concerning maintenance and a maintenance contract.
