Advantest (ADCMT) 7351E DMM teardown
« on: October 10, 2017, 09:30:50 pm »
Hello, after teardown of older, simpler Advantest R6441A here, I have another Japanese piece.

ADCMT 7351E.

There aren't many information about ADCMT equipment in English out there. But it seems these are very popular in Asia region, there are lot of them on Taobao and Yahoo jap. auctions.
I bought this on ebay.

I wasn't able to find out when this one was manufactured, but PCB silkscreen says 2006. It has USB connection and drivers for Windows are available. I will test it later.
It doesn't have many functions and features. But this DMM looks great ! I love VFD displays.

Mechanics is perfect. Assembly and disassembly is straightforward, no need of using force, compared to Agilent (like 34401A or 33120A).
And these neat screws marked with red and green marker.
I attach pictures.

Internals. There are a lot of unused footprints, definitely for higher models.

What's the reference? I don't see  the famous LM399.
