If the leakage current of the germanium transistor is quite high (due to warming from your fingers for example) the DCA55 can reject the correct pinout However it will then search for all other device types and configurations It can in those circumstances find a transistor of opposite type (NPN/PNP) and with the C-E swapped (although gain can be very low) Tests in a simple circuit
