(3) Adjust oscilloscope calibrator EDIT FIELD knob for 5 divisions of vertical
deflection on oscilloscope. If oscilloscope calibrator err display indication is not within
limits specified in first row of table 9, perform b (1) through (16) below. (No adjustment can
be made on TIs with main board (SN B056205 and below)).
(4) Repeat technique of (2) and (3) above for remaining rows in table 9.
(5) Move oscilloscope calibrator SOURCH/MEASURE CHAN 1 connection to TI
CH 2 input.
(6) Press MODE CH 2 and TRIGGER CH 2 pushbuttons.
(7) Set TI CH 2 VOLTS/DIV switch and oscilloscope calibrator VOLTAGE output,
at 1 kHz, as listed in first row of table 10.

NOTE
If necessary, adjust delaying time base controls for a stable
display.
(8) Adjust oscilloscope calibrator EDIT FIELD knob for 5 divisions of vertical
deflection on oscilloscope. If oscilloscope calibrator err display indication is not within
limits specified in first row of table 10, perform b (17) through (32) below. (No adjustment
can be made on TIs with main board (SN B056205 and below)).

b. Adjustments
(1) Connect oscilloscope calibrator SOURCH/MEASURE CHAN 1 to TI CH 1
using 24 pF normalizer.
(2) Set TI CH 1 VOLTS/DIV switch to 20 m and press CH 2 GND pushbutton to
in position.
(3) Set delaying time base MAIN SEC/DIV switch to 1 m.
