You can also use the SWEEP command to replace the NRDGS n,TIMER command
and the TlMER command. The SWEEP command's first parameter specifies the
interval between readings and its second parameter specifies the number of
readings. (The SWEEP and NRDGS commands are interchangeable: the
multimeter uses whichever was specified last in the programming.) For example,
the following program also takes 8 readings with a 1 second interval between
readings (this is shown in

measurements using the synchronous or random methods (SETACV SYNC or
RNDM), or for frequency or period measurements.
