Connect the meter between C and E, and then connect a resistor, like 22K Ohm between base and the suspected collector. Note the meter reading. If it is about 0.6 V, you got it on the first try. If not, reverse the C and E leads and repeat. Whichever way gives a markedly lower voltage reading has the transistor connected right, and the minus probe is on the emitter for NPN or collector for PNP.
