EXTOUT ONCE
Executing the EXTOUT ONCE command produces a single 1 µS pulse on the
multimeter's Ext Out connector. After executing EXTOUT ONCE, the mode reverts
to OFF (the EXTOUT signal is disabled). As shown in the following program.
EXTOUT ONCE is useful in subprograms to indicate the completion of the
subprogram, or a segment of the subprogram, to external equipment.
