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 functions, press <TST or TST> from the main menu and
the Test Functions will scroll at the top center of the display.
