(5) Adjust CH 2 POSITION control to position sweep within 1 division of center
horizontal graticule line.
(6) Adjust CH 1 POSITION and VOLTS/DIV VAR controls for 10 divisions of
horizontal deflection.
NOTE
When step 111 is performed, step 112 is also automatically
performed. No indication of step 112 will be shown unless a
LIMIT error is encountered.
(7) Press and release upper TRIGGER COUPLING pushbutton. Display readout
will indicate: (step) 113, 500 mV, BWL.
NOTE
In the following steps, if the LIMIT message appears, it
probably indicates that the upper TRIGGER COUPLING
pushbutton was pressed before the required signal was applied.
Press and release the lower TRIGGER COUPLING
pushbutton, verify the correct signal is applied, and then press
and release the upper TRIGGER COUPLING pushbutton.
(8) Press and release upper TRIGGER COUPLING pushbutton for TI step
numbers and oscilloscope calibrator VOLTAGE output settings as listed in table 22.

step 113 is performed, step 114 is also
automatically done. No indication of step 114 will be
shown unless a LIMIT error is encountered.
(9) Move connection from CH 1 to CH 2. Display readout will indicate: CONNECT
SIGNAL TO CH 2, (step) 121, 500 mV, 500 mV and BWL.
NOTE
When step 121 is performed, step 122 is also automatically
performed. No indication of step 122 will be shown unless a
LIMIT error is encountered.
(10) Set oscilloscope calibrator VOLTAGE output to 0.5 V at 1 kHz.
(11) Press and release upper TRIGGER COUPLING switch. Display readout will
indicate: (step) 123, 500 mV, 500 mV and BWL.
