First Let's start with the pinout of the VEMS unit
[Pinout] image
Bench level Tester
Done,
- TPS
- 16 LED tester installed
- 4 aux LEDs installed
- FP relay
- others not hooked up
- WBO2 pump(+)
100ohmnernst -100ohmpump(-) - primary trigger in (60-2 wheel setup +/- 2Vpp (0vdc offset -1Vmin,+1Vmax)
- secondary trigger hooked up but not in test setup.
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.
