Good evening; on this same model of multimeter, the Integrated Circuit: KS57C2616 (or WENS50) should you it be programmed by software for the multimeter works

I'm not sure what you are asking.  What is not working?  Can you measure a simple 9V battery?

Merçi have already answered. On my multimeter (vc650), the leading integrated circuitry was dead, he warmed the multimeter showed: OL and its consumption was 300 mA !! (Origin: WENS50), I was able to download the schema (even on this forum), and they put KS57C2616 .... I now put the new Integrated Circuit (I verified the magnifying lamp the state of the welds). But the problem is that it does not turn on. Therefore you must reprogram it with software, or there's some other explanation you there

Hello; replace 2 Integrated Circuits NJU4066 because the fuse has not played its role (rolled aluminum), and these components are destroyed!
