First Let's start with the pinout of the VEMS unit

[Pinout] image

Bench level Tester


Done,


Current problem

WBO2 setup

Board is 3.2 returned unit

WBO2 output readings hooked up to 100ohm test

gnd -- pump(+) 4.83V

gnd -- Nernst 4.38V

gnd -- pump(-) 3.95V

pump(-) --> pump(+) 0.886V

I am reading about the setup in the manual, but I'll gladly take any suggestions.

config setup has been tested from mt-027 supplied \mt-027\config (wintools upload) and from marcell's zipfile that uses a normal nernst ckt.

excepts included here.
