SETUP-CLOCK-TIME and entering the time in 24hr format. In a similar manner the date can
be entered by pressing SETUP-CLOCK-DATE and entering the date in a dd-mmm-yy format. If

adjusted by selecting the CLOCK_ADJ variable in the SETUP-MORE-VARS menu.

5.3.7 Diagnostic Mode

The M9110AH Diagnostic Mode allows additional tests and calibrations of the instrument.
These features are separate from the TEST functions because each DIAG function has the
ability to alter or disable the output of the instrument. While in DIAG mode no data is placed in
the DAS averages. Details on the use of Diagnostic mode are in Section 9.1.3.

MORE-COMM-BAUD, select the appropriate BAUD rate, then press ENTR.

message sent by the M9110AH. To set the ID press SETUP-MORE-COMM-ID and enter a 4
digit number from 0000-9999, then press ENTR. There are more RS-232 setups in the VARS
