    Where has this thing been all of my life?
  

*by S***E on Reviewed in the United States 🇺🇸 on 3 February 2023*

I had assumed in order to test components I would need an entire bench full of test equipment.  One for Capacitors, another for Transistors, etc.  To be able to test a 50-cent component, would I need to purchase $5K of equipment?  Then I saw this Tester used in a YouTube video.  When assembling electrical circuits on a breadboard, it is like cheating.  :-DREALLY happy with it.  I wish I had found it years ago!There are a bunch of these Testers on Amazon. They started as kits, then some mfgs decided to build an enclosure to house the components for a more professional look.They seem to have 2 basic designs, this one and the other "thinner" DROK unit.  I purchased the DROK unit first, since it looked more compact.  However, I quickly learned it has some serious issues. Obviously the ZIF (the aqua rectangle with the lever) was an afterthought. It fits in the socket, but the usual bumps on the underside of the ZIF (used to keep it above the PC board so solder can flow under it) keep it from seating properly. When moving the lever to clamp onto the leads of the component to be tested, the entire ZIF tips to the left. Unless you hold the ZIF in-place, the lever will unseat the pins on the right-side as it tilts to the left. Feels really wiggly, and very unprofessional. It could be glued in-place, but that seems like a ghetto work-around. The other option is to NOT use the ZIF and just put the leads directly into the socket. This would work, but it required forcing all leads into the socket holes simultaneously. For 2-lead components, this is fine, but for transistors or others with 3+ leads, this is much more time consuming. The ZIF allows the leads to be inserted "loose", and the lever does the clamping. Much more convenient! And that is why they added the ZIF to this Tester, (even though it is an afterthought).  That was the deal-breaker for me.  The DROK unit was returned.The Aideepen unit is solid.  The ZIF is fully incorporated and much easier to use.  I also like the way the data is displayed better.  On the left is the display from the DROK Tester. On the right is the Tester from Aideepen:DISPLAY(Please refer to the image.)Both Testers are testing the same component, which is a simple transistor.The part I do NOT like about the DROK display is the pins are labeled as "123=EBC", which means I have to translate the pins to the EBC (Emitter, Base, Collector) pins of the transistor.A better way to display this information is to place the EBC next to the pins (1, 2 & 3) in the diagram. This is shown in the screen shot on the right. Much less mental gyration required to correlate the pins to the EBC of the transistor.BATTERYThe DROK unit uses a 9-volt battery for power, not included. It displays the voltage of the battery on the screen. In fact it takes up the bottom 20% of the display, which is a bit of a waste. I would rather see more room for info about the component being tested than the onboard battery.Speaking of batteries, it eats batteries. I ran maybe 10 tests of different components. The battery started at 9.3v, and was drained to 9.0v. If a typical session requires the testing of 20 components, I would need to keep a spare battery around, or purchase pricey rechargeable 9v batteries. Conversely, the Aideepen Tester has a rechargeable battery on-board.There are 3 version of this Tester.  I can't see a whole lot of difference.  I assumed the most expensive one would have the latest firmware and be the most bug-free.  (It might well be that the less expensive ones will work just as well, but it wasn't worth the saving to find out it doesn't after the 30-day return window closes.  They are reasonably close to $30.  Frankly, I would expect a Tester this sophisticated to be closer to $100. They are a bargain.One thing I wish it did was to test SMD components.  If some extra pads were added, or an simple PCB were etched with some legs to insert into the ZIF, then it could.It is a bit of an Easter Egg Hunt to fine-tune it based on what I think the ratings should be.  Does the component work properly, or is my circuit not working because the factory sent me a bad component?Being able to KNOW the component is "good" helps give me the confidence to troubleshoot my circuits.HIGHLY RECOMMENDED!

    Very Nice
  

*by J***. on Reviewed in the United States 🇺🇸 on 5 November 2021*

The T7 TC-T7-H LCR tester is a keeper.  Shortly after I received the tester, I had a booster amplifier to repair. I quickly found two open and one shorted transister. Then went back and found an open emitter resistor.  It was so nice to be able to connect any lead to any connection on the transistors.  Then to have the gain shown so I could match a pair of output transistors.  Unfortunately, the transistors have to be removed from the circuit for testing.  But that was expected.  Great tester for the price.
