(7) Set oscilloscope calibrator output to standby.
(8) Set TI CH 2 VOLTS/DIV switch to 2m.
(9) Set oscilloscope calibrator CH 2 for a VOLTAGE output of 10 mV at 1 kHz.
(10) Adjust TI A TRIGGER LEVEL and POSITION controls as necessary to view
(11) Rotate oscilloscope calibrator knob located below EDIT FIELD key for 5
divisions of vertical display. If oscilloscope calibrator Err display does not indicate within
limits specified in first row of table 4, perform b (41) through (82) below.
(12) Repeat technique of (8) through (11) above for settings listed in table 4. If
oscilloscope calibrator Err display does not indicate within limits specified in table 4,
perform b (41) through (82) below.
