Review: I should have ordered this item sooner. Test don't guess! - I have really wanted one of these for a long time but it was hard to justify it as a need. Now that I have one I see how much of a value it is! Sure it's quick and accurate and enables you to test not guess if components need replaced but that also enables you to fix previously unfixable things. This item does feel very delicate and while it's likely plenty durable it did not come with a case so I do want to find a proper case to keep it safe yet readily available. I am impressed with how many components it can identify, it is very versatile with anything 2/3 wire. This is the kind of item that doesn't cost you money it saves it if you actually need it.
Review: A fast and reliable tool - This thing is pretty handy. Its a little pricey but if you use a lot of transistors like me its will be invaluable. The DCA55 is quick to determine if its a silicon or germanium, PNP or NPN transistor and gives you pinout, HFE, VBE, leakage and test current. For diodes its more straightforward giving you forward voltage, anode and cathode. For JFETs it essentially just gives you the pin out. I have not tested MOSFETs yet. One point of advice is to not hold the transistor or diode in your hands or fingers when testing because the heat will cause the transistor or diode to read higher than actual test values.

## Questions & Answers

**Q: Can this measure resistors and capacitor? If not does atlas make one that does test both ?**
A: This Atlas model doesnot measure resistors and capacitor, but you can do it with the Mega 328 ESR transistor, resistor, diode, capacitor and mosfet tester for less than $15.00 .

**Q: Does this only identify the component or does it test it as well?**
A: It not only identifies the type of transistor but gives you key current/voltage and gain characteristics also.

**Q: Will this device check or test and specify thyristors?**
A: Yes.

**Q: Is this version 3.0?**
A: Mine is a version 2.93 but I bought it in Jan 2013!!  Not sure what the current selling rev is..
