adjust
the

control until the end of the intensified
bar
that
is mO\'ed by this
control is positioned exactly
at
the selected transition in the
waveform.
NOTE:
Ignore
the

second
end
of
the
interuified
bar.
4.
While looking only

The Delta Time function
allo",-s adjusting a circuit to a pre-
determined time. The Delta
Bar
is adjusted until the desired
time is displayed in the digital readout. The circuit
is then. in
turn, adjusted until the
waveform falls into the intensified
area.
To adjust a circuit to a predetermined time:
l.
Press
the .6TIME button.
