The Signal Generator is set to output 4.00 V, “positive only” square AC Waveform, at 0.40 Hz.
The “ON/OFF” button is set to “Auto” so the Signal Generator will start automatically when you
click MON (Monitor) or REC (Record) and stop automatically when you click STOP or
PAUSE.

PART II: Sensor Calibration and Equipment Setup
•
You do not need to calibrate the Voltage Sensor or the Power Amplifier.
➀
Place a 100 ohm (
Ω
) resistor (brown, black, brown) in the pair
of component springs nearest to the top banana jack at the lower
right corner of the AC/DC Electronics Lab Board.

➁
Connect a 330 microfarad (
µ
F) capacitor between the compo-
nent spring on the left end of the 100
Ω
resistor and the compo-
nent spring closest to the bottom banana jack.
➂
Put alligator clips on the Voltage Sensor banana plugs. Connect the
alligator clips to the wires at both ends of the 330
