Question 1

What's the difference between this and a basic digital multi meter?

Accepted Answer

This is NOT a multi-meter, because this actually outputs voltage from 0 all the way until 300V but it will stop when there's resistance (meaning the LED/light bulb starts to light up, at least that's what I think is happening). But a multi-meter only detects voltage and not pass voltage to be able to light up an LED for example.

So with this device, you don't even need to power up your TV or LED that you are testing, you can just have an LED light strip for example not connected to anything, and with this device you place the RED lead on the + of led strip and BLACK lead on the - of the led strip and the led strip will light up after a few seconds, if it doesn't then the led strip is broken.

Hope that helps, I used it to fix a broken Sony TV that would not power up (because some of the LED bulbs inside went bad).

Question 2

I got shocked. Did I do something wrong because it says no electric shock on it?

Accepted Answer

if you touch the LED bar/bulb at same time as you testing depends on bar you might get shocked since there is current going over it . But I never got shocked if I just touch the probes themselves .

Question 3

Im wondering... Would this tester work for testing car fuses as well??

Accepted Answer

No, I would not think so.  This is basically a voltage and low electric current generator and monitor.  What you need is a continuity tester.

Question 4

"Output Voltage :0-300V "........ ac or dc?

Accepted Answer

I got this one first and it DID NOT right it, it was supposed to check the back lights onTV  and see what worked and what didn't but what it did it put way to much voltage and it would burn the back lights out, so yo end up replacing ones that were good so after that mistake I got a little more expense and it worked just fine, the good one I got was X00249NZ1H, and it worked like it was supposed to, the way it works is when you check the back lights it would send the correct voltage and light them up so you know how many you have bad, you may get lucky and only have one blub not working on the strip and that will stop them all from working, hope this helps.
