Operating the M703E Calibrator M703E Calibrator Operator’s Manual
6.1. 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 Chapter 11). 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.
