4.1. TEST FUNCTIONS
A variety of TEST FUNCTIONS are available for viewing at the front panel whenever
the calibrator is at the MAIN MENU. These measurements provide information about
the present operating status of the calibrator and are useful during troubleshooting (see
Section 8). Table 6-1 lists the available TEST functions.
To view these TEST func
tions, press <TST or TST> from the main menu and the Test
Functions will scroll at the top center of the display.
