The trigger delay is the period between the trigger signal and the
start of the measurement (burst). The trigger delay set by
CONFigure
is 0 seconds for the DC voltage function. The
TRIGger:DELay
command is used to set delays up to 16.7 seconds.

The multimeter output buffer can hold eight readings. When the
buffer fills, measurements are suspended until readings are read from
the buffer (by the computer) to make space available.
