Service software log file The Service software generates a log file for all tests performed This log file. is located in the folder on delivery, c programme Cerec System Service Protocols and is named. Testdatei XXXXXXXXXXXX TXT, The Xs here denote the serial no of the milling unit.
Each time the service software is started a confirmation query appears. asking whether this file if it already exists should be deleted If No do not. delete is selected the tests subsequently performed will be appended to the. ones previously saved Each test is labeled with a starting and ending date. The test file can be viewed with the editor at any time If the user quits a test. without saving it he will be asked if he really wants to quit without saving If.
