To educate the students on the basic principles of testing discrete
components such as resistance. Capacitance, Inductance, diodes,
transistors and filter circuits using voltage vs current (V-II)
characteristics. Using this trainer basic power electronics
components such as MOSFETs. diacs, triacs, SCRs and opto
couplers can also be tested using trigger pulse & signature method.

Signature Method of Testing is also known as VI Trace
Characteristics, is a proven fault diagnostics technique In Power-Off
state while testing a board. By applying known wave from signal
with desired Voltage, source Impedance and Frequency of the
stimulus signals, depending upon the test node and its
characteristics, a Voltage (V) vs current (I) graph is plotted and
studied. It is a portable instrument.
