Buff ered
Re quests
Us ing the buff ered Out put chan nel ON com mand (page 6-66 ), even faster
meas ure ment speeds can be achieved. By us ing the ON com mand in stead of
the O com mand x number of times, ex tra proc ess ing is re moved, re sult ing in
im proved speed.
NOTE
Us ing FAST mode here will not in crease the speed as this
mode only works when ask ing for one meas ure ment at a
time ( i.e., the ‘O’ com mand only.)
