SECTION I1 - OPERATION
A. OPERATING INSTRUCTIONS (As two-axis recorder)
For sa.iisfactory operation of the Autograf the phenomena to be recorded must:
a. Be reduced to direct current, the available voltage being a linear function
of the original information.
b. Have amplitudes within the scale ranges of the recorder (XT input; 7. 5 mv
to 150 v; Y input: 5 mv to 100 v; range can be extended to 500 v, each axis).
c. Vary at a rate within the response capabilities of the instrument.
Frovided the above signal conditions are met, the Autograf may'be placed into
operation as follows:
1. Connect the power cord to a 115 volt, 60 cps line and turn the unit on by
moving the Power switch to the IlUPtt position. The pilot light will indicate
that power is applied.
2. Place ink in the pen reservoir. This is done using a hypodermic syringe.
Do not completely fill the reservoir and use Esterline-Angus recording
ink only. Apply a syringe to the filler hole to force ink through to the
pen tip.
3. Load paper as follows:
a. Place pen lift switch in I1UPt' (vertical) position so that pen is off
the paper.
b. Turn the servo switch OFF. (down position).
c. Push the carriage by hand to approximately 4" from the left-hand end
of the recording table.
d. Slide paper under the carriage onto the paper bed.
e. Align paper with table edge scales.
f. Turn vacuum switch rrON1l. Readjust alignment of paper with scales
and smooth out paper surface.
g. When paper is to be removed, turn off vacuum switch to save wear on
P-P.
4. Connect the X and Y components of the data to be recorded to the X and Y
input terminals and set the scale range switches to the expected maximum
value s.
