It is indispensable to the measurement of the time of
waveform.
Bright line is moved toward right when the knob IS ro­

this case, the sweep time is I /10 of the value indicated
by TIME t DJV . Bring the position of the waveform
to be magnified for observation from the center of
the scale by operating =::POSITION of the horizontal
axis. Next.switchxiOMAG switch to PULL (pulled
out state). Then the waveform placed at the center ts

in this case is I
