(5) MAG pushbutton to X1 (IN).
(6) TIME/DIV switch to .2 ms.
(7) DLY TIME switch to .2 ms (PUSH FOR DYL'D).
(8) VARIABLE control fully cw to detent.
(9) Delayed triggering pushbuttons as listed in (a) through (c) below:
(a) SLOPE to + (positive) (IN).
(b) COUPLING to AC (IN).
(c) SOURCE to INT (IN).
(10) DLY'D TRIG LEVEL control adjusted to RUNS AFTER DLY TIME.
(11) DELAY TIME MULT control to 1.0.
f. Pull oscilloscope POWER switch to on and allow at least 15 minutes for warm-up.
CAUTION
A sharply focused, high intensity spot will damage crt screen.
Use lowest beam intensity possible for suitable viewing.
g. Adjust oscilloscope INTENSITY and FOCUS controls for optimum trace on
oscilloscope.
CAUTION
Remove oscilloscope power when required.
8. Calibrator
a. Performance Check
(1) Connect TI calibrator to CH 1 INPUT. (For Tektronix, Type 7603, connect TI
calibrator 4V and GND to CH 1 INPUT).
(2) Position vertical amplifier VOLTS/DIV controls for 5 divisions of vertical
deflections on TI.
(3) Disconnect TI calibrator from CH 1 INPUT, and connect to oscilloscope
calibrator SOURCE/MEASURE CHAN 1.
(4) Set oscilloscope calibrator VOLTAGE output to 1 VOLT (for Tektronix Type
7603, 4V).
(5) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton for
5 divisions of vertical deflection on TI. If oscilloscope calibrator err display readout does
not indicate within r1 percent, perform b below.
b. Adjustments
(1) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton for
err display of 0.0 %.
