Experiment 5: Rectifi ed AC, dual phase
Connection layout:
Connection summary:
GND clip : 4
Probe tip : 5
Purpose:
The purpose of this experiment is to show what dual phase recti
fi
ed AC looks like on a scope screen
and to show the difference with single phase recti
fi
ed AC.
How?:
Turn on the HPS140 Handheld Pocket Scope
1.
(see HPS140 manual for How-To instructions).
Place the probe switch “x1/x10” to ‘x1’.
2.
Select 5ms/div and 4V/div.
As the switch is still set to single phase recti
fi
cation , the display will show the same trace as
with experiment 4.
Now, check what happens when you
fl
ip the switch from single phase to dual phase recti
fi
cation.
Flip the switch back and forward, to clearly see the difference between both settings.
