## Questions & Answers

**Q: I am trying to measure a inductor and it keeps coming back with a resistance.  How do I fix this?**
A: I found out that the tester can’t measure inductance below 10uH. It helps to buy a pack of inductors of various values to always check the tester. This is how I found out that mine cant’ measure inductors below 10uH.

**Q: Can it be powered with a cable?**
A: I did a simple mod in order to power it from a basic 9vdc power supply l. I simply installed a standard 12mm polarised jack into the case  (theres a slot in the top center of the pcb to allow room) and use a currwnt limited wall wart or bench top piwer supply for the required 9 volts  (solder the 2 wires from the jack  to the battery terminal connections on the pcb matching polarity). Mine has worked a charm and no worries plus you have the option of using either power source. If you would like to know more on this mod reply and I will supply you with a more detailed step by step with photos.

**Q: will this tester work with germanium transistors? also, does it report transistor leakage?**
A: I haven't found a germanium transistor to test yet, but I have tested Ge small-signal diodes with mine, so I'm fairly certain this tester can properly identify and test Ge teansistors as well.   If so, it will show the device type (PNP/NPN), ID the leads (BCE), and show the hfe (gain), but it will not show a leakage current value.
   The primary diference between Ge and Si devices is the difference in the voltage drop across a forward-biased junction. Ge junctions show a 0.3 - 0.4v drop, and Si junctions show 0.6 - 0.7v.

**Q: will it tell me the pin identification?**
A: With in reason.  You will need the spec sheet, say you have a bad unit, it may identify it as two diodes and you know it is not two diodes, it is a 222.  So YES it will / it has done it correctly for me on good devices, on devices that fail, it may show unknown device or something like a mess of diodes  or something else.  Nothing the spec sheet would show.  hope this helps.  I also use a Heathkit transistor tester so I can supply a load.  If you are working with hard to replace /find items, I suggest you also get something that will supply a real load so you can see if it breaks down after 2 minutes or something like that.  hope this helps,  I am pleased with cost vs use I have gotten.  SO far so good.  Get used to getting the pins in 1 2 3 any way, but 1,2,3.   George
