## Questions & Answers

**Q: Can it test for bad capacitors (ESR) in-circuit?**
A: In order to test the capacitor more accurately, we recommend that it's better to remove the capacitor and test it.If you need further help,please contact support team longrunerus@hotmail.com

**Q: Has anyone used this to test germanium transistors?**
A: Our equipment can only test what type of the device is, such as a transistor or a diode, or a germanium transistor or a silicon transistor.

**Q: Does it use identify zener diodes?**
A: Yes, the method is in the instructions

**Q: Please define hfe, ie, ube, iceo, ic & bjt ?**
A: All of these are transistor specification labels.  Such as hfe stands for current gain, iceo is the current between collector and emitter with the base open and the last that I know off hand is bjt.  That is Bipolar Junction Transistor.  Ic may be the maximum collector current.  I don't know what ie and ube. You may want to look at a textbook on transistor specifications.  Try 2N2222, a very popular device.

## Customer Reviews

### ⭐⭐⭐⭐⭐ YES!  THE GREATEST OF ALL TESTER. . . A++
*by A***E on May 27, 2020*

Excellent Digital Tester. . . Super Accuracy Performance. . . We had it for 2 years ago and we use it a lot to check and verify each Electronic part or device that we order and it tells us if the part is OK or if it goes outside the manufacturer's specification parameters..."Great precision in relation to ESR". . . And the most we like about it is that it doesn't need batteries the meter, we only connect it to any USB and it charges quite quickly and the charge lasts for a long time... With a single charge we have tested more than 150 pieces and continues with something charging, so the battery is excellent too...I recommend that all those fans & hobbyists of Electronics buy that tester model... It has all the necessary information to give you a complete reading of the piece that you are testing and verifying... 2 years with us and continues working as fresh new from the factory...Was worth every penny we invested in this TC1 tester. . . Very happy with it!!!Also fast shipping too with no issues and packed safely.We recommended 100% . . . A++

### ⭐⭐⭐⭐ Incredibly useful (with a few quirks).
*by L***R on November 5, 2023*

While Hfe accuracy can jump around (while keeping the same transistor in this device untouched for hours), this device is a must have for any electronic hobbyist or anyone working with electronics. It is especially useful for determining NOS part orientation, poorly marked components, or troubleshooting vintage equipment for restoration. The accuracy seems to go down as the charged-power drops -- you will notice the accuracy drop before it loses charge, as the reference voltage seems tied to the available charge. The jumper clips are the cheapest possible and will break easily because they are poorly designed and manufactured. I use it all the time with no regrets.

### ⭐⭐⭐⭐⭐ Excellent Product. It Can Replace the Big Bulky Testers You Have
*by D***. on August 24, 2020*

Excellent product !Very accurate and simple. Capacitors, resistors, diodes, NPN transistors, PNP transistors, etc. No problem.Just hook it up and this baby will figure it out for you :)I wish the transistor test could be more detailed like those $100 Peak testers.For very little money, it replaced my big, bulky, turn-the-dial testers - the ones you have to turn the dials and pray it’s in the right setting things.Leads or no leads (direct) - accurate.Great product!
