(10) Perform steps a through c below:
(a) Use technique of (b) and (c) below for TI VOLTS/DIV switch settings and
oscilloscope calibrator VOLTAGE outputs listed in table 3.
(b) Rotate CH 1 POSITION knob to center trace on TI crt.
(c) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton
to obtain 6 divisions of vertical display. Oscilloscope calibrator err display will indicate
within limits specified in table 3; if not, perform b below.
