Victor 4080 LCR meter
« on: March 14, 2019, 06:25:21 am »
Victor 4080 LCR meter, bought for about 100$. Had it for a while (about a year) and just though I'd write a short summary of it.

I use it mainly to check unknown/unmarked caps and inductors, but also for troubleshooting broken electronics.

Has rechargeable battery inside (use mini-USB connector). Came with 2 banana to crocodile clips, and they work for the most part, but struggle at certain values/frequencies. Has option to plug 4 wire connection, which I made using a 2 sided copper PCB (just filed away the copper between connectors and soldered cables to it). Yes it is a shitty cable but results show they work just fine (has since made a new and improved cable).

Opened it up and took a few pictures (sorry for the bad quality).

Measured it against a recently calibrated Hioki IM3523 at work, and the results were not bad (see Libre Office file).

Small portion of test for lazy people:

1.5mF, 100Hz

LCR METER       Cs      Rs Ω      D
Hioki IM3523(4w)   1.455   0.05585   0.051
Vc4080 (2w)      1.457   0.0565   0.052

I'm happy with the buy and it still works fine after having it for about 1 year.

If anyone want any other/more information about it just ask.
