(25) Calculate vertical gain using formula below. Calculated result will be within
limits specified in first row of table 1 below.
V avg. 2 - V avg. 1 = vertical gain
(26) Repeat technique used in (13) through (25) above for remaining TI settings and
calibrator outputs listed in table 3. Calculated results will be within limits specified in
table 3 below.
