they are clones / rebranded models of the et430 series, et430b, et431, et432
the et43x on the board is a give away
Rebranded afaik. VC4080 is ET430 and VC4082 is ET433
looks like Victor rebranded only these 2 from (Hangzhou Zhongchuang Electron Co.,Ltd.) East Tester® ET43 series.
VC4080 (ET430) is more cheap and bit less accurate and no DCR, no DC bias, fixed test signal level.
ET431 (max 10kHz),432 (max 100kHz) have also fine adjustable 0-500mV(1mV) DC bias and 3 step adjustable test signal levels
VC4082, (ET433) all same but test signal level 0-0.7Vrms can free adjust and test frequency can free adjust between 100Hz - 100kHz (1Hz).
If do not need free adjusted test level and three steps,
0.1, 0.3 and 0.6Vrms is ok and if do not need free frequency and freq steps
100, 120Hz, 1, 10, 40 and 100kHz is ok then this ET432 is, imho, good selection and nearly half price from ET433(VC4082). Also free adjustable DC bias is very good feature.
I have looked and searched these here now more than month because I need one LCR and I am far from my homeland where I naturally have all instruments.

ETA: now in hand, ET432. Also Kelvin clips are standard included with this model. Feels better than I expect. 1199 RMB. (154 eur). Example one model what I also look was Der EE DE-5000 but this was very soon dropped out due to its lack of adjustable DC bias and lack of adjustable test signal level etc.
