## 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..
