RESISTANCE/DIODE TEST
1) Measure a resistor of about half of the full scale value of each resistance range. Compare the kit meter
readings to those from a meter of known accuracy.
2) Measure the voltage drop of a good silicon diode. You should read about 700mV. Power diodes and the
base to emitter junction of power transistors may read less.
If any of these tests fail:
a) Check the values and the soldering of resistors R1 - R6, and R12.
h
FE
1) Set the range switch to h
FE
and insert a small transistor into the appropriate NPN or PNP holes in the
transistor socket.
2) Read the h
FE
of the transistor. The h
FE
of transistors varies over a wide range, but you will probably get a
reading between 100 and 300.
If this check fails:
a) Check that the transistor socket is aligned according to Figure D.
b) Check the value and soldering of resistors R10, R11, and R29.
FINAL ASSEMBLY
