 The Hameg HZ65-3 is a crude device for plotting an I-V graph of a two-lead component either in the front panel sockets or connected via the 4mm banana sockets on the side. If you have a three lead device such as a transistor, then you have to supply the third voltage externally; a storage scope would be very useful when recording the family of curves. The Hameg HZ65-3 is a crude device for plotting an I-V graph of a two-lead component either in the front panel sockets or connected via the 4mm banana sockets on the side.

 It works by putting a 50Hz voltage varying sinusoidally between -7V and +7V across the DUT, and measuring the current. Since the maximum voltage cannot be changed, there is the possibility of damaging the DUT. It works by putting a 50Hz voltage varying sinusoidally between -7V and +7V across the DUT, and measuring the current.
