AE20218 Milliohm Meter Kit, 0.1 Milliohm Resolution, Four Wire Measurements bought one

I have been in need of a mega ohm meter for a while but just could not make up my mind to which one I want to buy and this one has a couple of things going for it can also be used on a computer to display a resistance graph plus it is a kit that you put together supposedly the only parts installed are the surface mount components

I will probably make a rechargeable battery pack for so it can be used as a portable device and anywhere

I kind a wish that it had a higher resistance value higher than 240 ohms at 10 milliamperes on high range but it is what it it
On the lower range it is 24 ohms at 100 milliamperes I am wondering if this voltage is to high when troubleshooting a circuit board will it activate components at a test voltage of 5 volts

I have been using my blue ESR meter for troubleshooting short circuits and it somewhat works fairly well but it not the perfect solution for what I really need to use it for one reason is that if it sees a short it does not go as low as I would like it to go because once is registered a short it stops and that reading

I am going to buy the one that is used in the automotive troubleshooting it made from the same manufacturer of one of my battery operated battery tabbing machines that I have they seem to make good quality devices

Resistance measurement range is up to 200Ω and the voltage measurement range is up to 100 V. The device must not be used with a DC voltage higher than 100V. Do not apply AC voltage under any circumstances.

I might be making some high voltage battery packs in the future so this is the reason for considering this testing device as well

this reminds me, i was experimenting with the Fnirsi meter yesterday and on a whim i metered a bad cap i just removed.
it actually gave me the same ESR as my component tester did!
i need to scope this thing and see what it's using to do tests!

If you do scope out the bad capacitor can you please post the results from your scope I would be very interested in this

i'll give the capture-mode a try

I finally got this kit in the mail but I have not had time to put it together yet maybe this weekend but we will see between I have some thing that might be more pressing to get done instead but we will see what happens
