@ VAR Controls Provide continuously variable, uncalibrated deflection
factors between the calibrated settings of the
VOL TS/DIV switches. These controls vary the deflection
factors from
calibrated (fully clockwise detent position)
to at
least 2.5 times the calibrated deflection factor (fully
counterclockwise position). When out of the calibrated
detent, a greater than
