How does this tester work if it is not a load tester?

its not a load tester. it uses different system i think. i have a battery. it shows it needs recharge. but cca is ok... i dont understand is it working or can i trust its test...

It measures the battery's ability to deliver high currents. The lower the battery internal resistance the greater current it can deliver. The tester places a very high load on the battery for a extremely short time and measures the current flow (or voltage drop). It then calculates the cold cranking amp value. As long as the battery has some charge it can "predict" the ability to deliver current when fully charged. I have stopped using my load tester since buying this tester.

It test the polarity etc. of a regular receptacle. It does not trip the breaker in the panel that feeds the receptacle. Hope this answers your question.

It's easier than you think. The compartment below is for spare battery storage. To test simply lay the battery face down on tester. Hope this helps.

I have not put mine to work yet my project is taking longer then i thought, will post outcome with resaults once it's tested sorry could not help you on info. at this time.

No you will need a seperate tester for that. Does great for everything else though.

Yes we can. The tester splits into two parts. The parts are connected , one to each end with the main part with display at the end where you want to see the result.

i wouldn't test it. it's a good stand alone unit for medium weight stuff, even books, but it's not designed for that kind of load.

I have no way to test, so am interested in your experience. I must say I had my doubts. sounds suspect to me!

Don't know but probably not reliably. It would depend on the amplitude of the signals the tester uses to execute the tests and the nature of the circuit that the cap is in. There are lots of comments/blogs out there about this tester if you google around.

This item does not require batteries to work. The tester uses the charge in the battery being tested (if the tester doesn't light up, the battery is dead).

Only if the tester supplies the load. The power supply gets connected to the tester or the system, there is no provision for in-line. But it was under $10.

I bought this for my husband and he said he has no experience with the Test-Um's Resi-Tester. Sorry we could not help.

It can not test any battery well. There are other testers better then this. There is an inexpensive tester out there. I do not have the model number. It is black with a red slide to make contact with the terminals of the battery. It works great.

It tests all the batteries that it is designed to hold. AAA, AA, C, D, and 9V. 9V has a special spot on the tester. The others are all similar voltage so they use the spring loaded testing arm.

This is just a simple electrical tester. It sends a pulse down each wire to see if there is a response on the other side, i.e. it doesn't traverse switch ports.

As L Hou said, the power supply provides power to the tester, specifically through the large ATX board connector. You don't have to plug in the other connectors if you don't want to test them but the instructions specifically state that if the tester doesn't light up your main board power is bad.

No. I tis designed to test off the shelf batteries. I personally have used it to test rechargables. It works on some but not on others. Have no idea why.
