The compact test probe
is made from five transistors, three LEDs, a zener diode,
and three resistors. It enables rapid 'measurement' of voltage
levels at digital gates, fuses,
diodes, batteries, and others. Of
course, it does not provide absolute values,
but rather a good
indication of correct operation
or otherwise.
