i would look at 5.5, instead 4.5 ....
GW Instek GDM-8251A
Fluke 8840A ; 8842A
HP 3478a - primitive, abit slow, but crazy accurate and cheap
All of these have 4 wire kelvin too, which the VC8145 does not. I don't see any handheld meters have unless it's called a milliohm meter. I'm happy I found my Datron 1062 for $50, just needed a electrolytic and tantalum recap. Some of the tantalums smoked.
I think there should be a cheap bench meter for the same reasons I picked up mine:
- A sweet display
- Buttons for convenience and speed.
- 4 wire kelvin measurement
- Various modes and Compute functions (that I don't know how to use yet because I'm a noob, soo... not a good reason lol)
- Super fast autoranging. (0.74 seconds infinite to short, 1.4 to infinite).
Now, if only it would beep.
What is the cheapest multimeter with 4 wire kelvin? With a quick look I see the Siglent Technologies SDM3045X $389 USD
I guess if you are on a budget, you'd make yourself a current source instead and just use a handheld.
