Now I need some sort of Joe Lightning intro for all my videos along with an action figure.   :-DD   
Fits you quite well IMO Joe, when at home busting meters, sparks and smoke all over the place and when you're on the drag bike .....lightning fast !

Nice job with that new "spare parts" diff probe, Joe.

Hi there, im looking forward to see how the mertek meter performs. In addition to comments on the video, could you show the ceramic fuses internals?

I plan to pull both fuses apart after seeing where they open up at.

It works better than I expected it would.  Looks like the price for the MICSIG DP10013 jumped $30 USD on Amazon since the last time I looked.

Hi there

Is this the same  MICSIG DP10013  model  ?

https://www.ebay.com/itm/Micsig-Oscilloscope-1300V100MHz-High-Voltage-Differential-Probe-Kit-High-Quality-/123239228604?roken=cUgayN&soutkn=EvpMYC

But off course you get the risk of getting stuck..

Yes, but consider its $200 for shipping plus the price of the probe.   They will not sell very many like this.

Looks like it's $140 to $160 on eBay

Really.  At $50 and free shipping, I would roll the dice.  Even at double that, I might pick one up.   I've never had a need for a high voltage differential probe at home.   They have a UT181A for a hundred bucks, $300 in shipping.   :-DD

One thing I was going to look at was the input impedance but I never finished the software for this analyzer to do it.

Nope, free shipping for that too. Ebay says: "Based in China, dannuer has been an eBay member since Apr 17, 2018"  :bullshit:

That meter is as buggy as the 121GW.  How come the two "reviews" that were posted don't show these problems??   They give it the old thumbs up, five star rating.. 

I'm currently watching the one that was posted in the comments.   At 13:20 it reminded me when I was attempting to get the Gossen apart.   The boot is tight.

He seems to like it as well.

If I understood his last comment, he has a store and plans to sell the meter.  Similar to the other review where the retired guy gets his free bling for giving thumbs up.   In my case, I could care less.  I'm getting nothing out of it.

Don't know what to make of the guy frankly. He doesn't know that much but hey, that never stopped me much..  I've always been high on tinkering and lazy on math, but since I got my first job in electronic's in '76 at AEG Telefunken, I've been hooked.

I think anyone can "do a store" on Amazon. They do all the work and you just decided what products to recommend. I doubt there's much money in it, but I was thinking of your shortage of TTL when I saw that huge grab bag in his store.

He’s going to put it in his “store”, wonder what the markup will be on a $9 meter? :)

That's just the thing, it's not really a store. He ships nothing, it's just a URL forwarder (IMO) that gives him a dime if Amazon's honest.. I think there's kick-backs like, if there's enough action, providers might send him a kit.. whatever

All the thrills of being able to say, "I've got a store" and no real work..

For a dime, maybe no bias then.   So far there are nine things I am not real impressed with.  But for $10, it's like the free HF meters.  You just can't bitch too much about them. 

The more problems I keep coming across, the less I am inclinded to try and improve it.   That said beyond the destructive tear down of the fuses, just let me know if there is anything else anyone would like to see.    Chemical and drop test are already covered.   Like every meter I run, don't wait until after to ask any questions you have.

Hi there.

Does this device is prone to RF interference ? Can you pass the RF antenna to check that  its readings are changed ?

Speaking of RF, putting it on the input jacks would be good too. The U127xA had an issue with that.
