MAN UAL trig ger only func tions cor rectly on non- repetitive sam pling,
i.e., the PRO FILE PE RIOD needs to be 6ms or greater.
The dis play shows an ‘x’ mark ing the trig ger point. This trig ger point
mark ro tates as the pro file data is up dated, chang ing be tween 'x' and '+'
on each data up date. On rapid up dates, the trig ger point mark may ap -
pear like a star (*), as it is ro tat ing so quickly. In man ual, ex ter nal or
GPIB trig gered dis plays, the mark ro tates at a slower rate and each true
data up date can be seen.

TR3 com mand will re turn the sys tem to its pre vi ous state if the TR0
