Click on Components button for components to pop up.
Click on the component, drag them to the test bench and place them as shown in the experiment setup.
After placing the components on the test bench, connect the wires accordingly.
To check your connections click on "Check Connections" button.
If your connections are correct then you may continue to take down the readings, if not then click on "Reset Button" and try it again.
Move the "Beam Voltage" knob and set it to 250 or above to record your readings.
Toggle the switch button and move the "Reflector Voltage" knob to set the reflector voltage to maximum negative value.
As soon as you start varying the reflector voltage you will observe a voltage value on millivoltmeter.
Keep varying the "Reflector voltage" till you get maximum voltage at millivoltmeter.
Note down the value for Output Voltage from millivoltmeter
Click on "Add to table" button to record the readings for Output Voltage, Beam Voltage and Reflector Voltage.
Click on "E-Plane" button to check its basic properties.
