    components that are not connected to other parts Is the DCA75 ok with germanium transistors can it measure leakage current and does it take into account the leakage current for it s gain measurement Yes The DCA75 will detect the germanium or silicon type of semiconductor It will measure leakage current and it takes that leakage into account when measuring gain unlike most multimeter h FE measurements I ve noticed the leakage current of my germanium transistor gradually drop with each subsequent measurement Is the battery failing or something else wrong Leakage current is extremely temperature dependent and particularly noticeable for germaniums as the current is fairly high to start with The leakage current can double for just a 5 C increase in temperature So after some handling the transistor temperature slowly falls and can lead to a decreasing leakage current That s completely normal and correct Additionally DCA75 test currents are completely independent of battery condition The Collector and Emitter of my germanium transistor is showing the wrong way round is the DCA75 wrong If the leakage current of the germanium transistor is quite high due to warming from your fingers for example the DCA75 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 with the C E swapped although gain can be very low Tests in a simple circuit confirm that you can get a germanium transistor to work with some gain in that way So the DCA75 is not wrong it s just found a configuration that yields a low leakage current Try keeping your transistor cool during testing to avoid this situation Can the Atlas DCA75 measure Zener diodes Yes The DCA75 can test Zener diodes up to around 11V Zeners with a reverse voltage of less than around 8V will be tested at 5mA higher voltage ones may be tested at a lower test current The test current is confirmed on the display Can I use the DCA75 to match transistors Yes The main parameters that you may be interested in are h FE and V BE Both of these parameters are measured by the DCA75 This enables you to group your transistors that have similar gain figures for example Additionally the use of the curve tracing facility allows even greater flexibility for your desired matching requirements Are Unijunction transistors UJTs supported No The DCA75 doesn t currently support UJTs although this is planned for a future release to be available via online upgrade too My MOSFET has a separate substrate or bulk connection what do I do with that lead Some rare MOSFETs have 4 leads gate source drain and substrate To enable the DCA75 to test these connect the substrate lead to the source lead If your MOSFET does not have a body diode then you will also need to connect a diode across the drain source leads What will the DCA75 show if my component is
