Testing Darlington transistor without built in diode.

One example part number of a Darlington transistor that do not have a
build in diode is the C516 (or BC516). If you refer to semiconductor data
book, it is stated as PNP Darlington transistor.

Since you already know that it was a PNP type Darlington transistor, then
you have to start testing it by using the red probe. The procedure of
finding the Base, Collector and Emitter is exactly the same as when you
test on the normal transistor. Set your analogue multimeter to X1 Ohm
and place the red probe to pin 1 of BC516 and the black probe to pin 2
and 3. If the pointer shows no movement, shift the red probe to pin 2
(middle pin) and the black probe to pin 1 and 3. If there is movement in
