(38) Press ∆t pushbutton to obtain a ∆t display and push SEC/DIV knob in for B
SWP only.
(39) Initially adjust ∆ control for a ∆t readout indication as listed in first row of table
16 and then
superimpose the two time
markers. ∆t
readout indication will be within
limits
listed in first row of table 16; if not, perform b below.
(40) Repeat technique of (39) above for remaining ∆t readout indications listed in
table 16. ∆t
readout indication will be within ∆t
limits listed in
table 16 if not
perform b
below.
