(a) TRIGGER SOURCE to select CH 4.
(b) VERTICAL MODE CH 3 off and CH 4 on.
(c) CH 4 VOLTS/DIV to display .1 V on CRT.
(36) Set oscilloscope calibrator for a CHAN 4, VOLTAGE mode output of 500 mV at
1 kHz frequency and SCOPE Z of 1 MΩ.
(37) Rotate oscilloscope calibrator knob below EDIT FIELD pushbutton to adjust
amplitude for 5 divisions of deflection on TI. If oscilloscope calibrator err display does not
indicate within limits specified in first row of table 8, perform b below.
(38) Repeat technique of (35) (c), (36) and (37) above for settings listed in table 8. If
oscilloscope calibrator err display does not indicate within limits specified in table 8,
perform b below.

(39) Reduce all outputs to minimum.
(40) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 10 mV at 1
kHz frequency.
(41) Press corresponding pushbuttons for indications as listed in (a) through (d) below:
(a) VERTICAL MODE CH 1 on and VERTICAL MODE CH 2, CH 3, and CH
4 off.
(b) CH 1 input coupling to 1 MΩ DC.
(c) TRIGGER SOURCE to select VERT CH 1.
(d) ∆V to indicate ∆V (cursors on).
(42) Set CH 1 VOLTS/DIV switch to 2 mV and adjust CH 1 VERTICAL
POSITION control to center waveform on display.
(43) Adjust ∆ REF OR DLY POS control to align reference cursor with bottom of
waveform for each of the following steps.
(44) Adjust ∆ control to align ∆ cursor with top of waveform. If ∆V readout
indications are not within limits specified in first row of table 9, perform b below.
(45) Repeat technique of (40) and (42) through (44) above for settings listed in table
