F. Increment the delay on the Digital Voltmeter to
the values listed below. At each increment note and
record the corresponding voltage under
"Positive Slope
Measurement"
m the Performance Test Record. (Each
increment represents a
10070
segment
of
the positive
slope.)

G. Measurements for the negative slope of the
Triangle wave are made by incrementing the delay on
the voltmeter to the values listed below. Note and record
the corresponding voltages under "Negative Slope
Measurement"
in the Performance Test Record.

D, Connect the 3314A to the Voltmeter as shown in
Figure 4-4.
E. Note the Digital Voltmeter reading. Record this
value on the Performance Test Record under "Positive
Slope
Measurement".
This is the
10010
point on the
positive slope
of
the Triangle (see Figure 4-5).
