(5) Adjust TI vertical VARIABLE control fully ccw to X10.
(6) Set oscilloscope calibrator output for 0.5 V and rotate EDIT FIELD knob for a 5
division vertical display on TI. If oscilloscope calibrator err display readout does not
indicate within r3%, perform b (2) below.
(7) Press 100 mV pushbutton in and adjust vertical VARIABLE control fully cw to
X1. Rotate oscilloscope calibrator EDIT FIELD knob for 5 divisions of vertical display.
Oscilloscope calibrator err display readout will indicate within r3%.
(8) Press 1 V pushbutton in and set oscilloscope calibrator output for 5 V, and
rotate oscilloscope calibrator EDIT FIELD knob for exactly 5 divisions of vertical deflection
on TI. Oscilloscope calibrator err display readout will be within r3%.
